Danger! - Dangerous electrical voltage!
Disconnect the power supply of the device.
Ensure that devices cannot be accidentally restarted.
Verify isolation from the supply.
Cover or enclose any adjacent live components.
Follow the engineering instructions (AWA/IL) for the device concerned.
Only suitably qualified personnel in accordance with EN 50110-1/-2 (VDE 0105 Part 100) may work on this
device/system.
Before installation and before touching the device ensure that you are free of electrostatic charge.
The functional earth (FE, PES) must be connected to the protective earth (PE) or the potential equalization.
The
system installer is responsible for implementing this connection.
Connecting cables and signal lines should be installed so that inductive or capacitive interference does not
impair the automation functions.
Suitable safety hardware and software measures should be implemented for the I/O interface so that an
open circuit on the signal side does not result in undefined states.
Deviations of the mains voltage from the rated value must not exceed the tolerance limits given in the
specification, otherwise this may cause malfunction and dangerous operation.
Emergency stop devices complying with IEC/EN 60204-1 must be effective in all operating modes. Unlatch-
ing the emergency-stop devices must not cause a restart.
Devices that are designed for mounting in housings or control cabinets must only be operated and con-
trolled after they have been properly installed and with the housing closed.
Wherever faults may cause injury or material damage, external measures must be implemented to ensure
a safe operating state in the event of a fault or malfunction (for example, by means of separate limit
switches, mechanical interlocks etc.).
Variable Speed Starters may have hot surfaces during and immediately after operation.
Removal of the required covers, improper installation or incorrect operation of motor or Variable Speed
Starter may destroy the device and may lead to serious injury or damage.
The applicable national accident prevention and safety regulations apply to all work carried on live Variable
Speed Starters.
The electrical installation must be carried out in accordance with the relevant regulations (e. g. with regard
to cable cross sections, fuses, PE).
Transport, installation, commissioning and maintenance work must be carried out only by qualified per-
sonnel (IEC 60364, HD 384 and national occupational safety regulations).
Installations containing Variable Speed Starters must be provided with additional monitoring and protec-
tive devices in accordance with the applicable safety regulations. Modifications to the Variable Speed
Starters using the operating software are permitted.
All covers and doors must be kept closed during operation.
To reduce the hazards for people or equipment, the user must include in the machine design measures
that restrict the consequences of a malfunction or failure of the Variable Speed Starter (increased motor
speed or sudden standstill of motor). These measures include: –Other independent devices for monitoring
safety related variables (speed, travel, end positions etc.).
–Electrical or non-electrical system-wide measures (electrical or mechanical interlocks).
–Never touch live parts or cable connections of the Variable Speed Starter after it has been disconnected
from the power supply. Due to the charge in the capacitors, these parts may still be alive after disconnec-
tion. Consider appropriate warning signs.

General
This Quick-Start-Guide gives a short introduction into the handling of the Variable Speed Starters DE1 (VSS). It
is assumed that the measures described in the installation leaflet, which is supplied with the product, have
been taken into account.
Variable Speed Starter DE1 IL040005ZU
Configuration module DXE-EXT-SET IL040020ZU
Please see manual MN040011EN for more detailed information.
Variable Speed Starters can be used for a plurality of applications as it comes out of the box. In default the
following functions are available:
DE1-12……. (0,25 … 2,2 kW)
oMains supply 1~ 200 (-10 %) … 240 V (+10 %)
oMotor feeder 3~ 0 - 200 … 240 V
DE1-34…… (0,37 … 7,5 kW)
oMains supply 3~ 380 V (-10 %) … 480 V (+10 %)
oMotor feeder 3~ 400 ... 480 V
Protective functions
oMotor feeder short circuit proof and ground fault proof
oMotor protection set to rated current of the device
oProtected against
Overvoltage
Undervoltage
Overtemperarture
Speed reference 0…10 V, corresponds to an output frequency of 0…50 Hz (60 Hz in USA and in Variant
DE1…N01)
3 digital inputs (High-Signal 10 … 24 V, either coming from DE1 itself or from an external source, e.g.
PLC)
oForward (FWD)
oReverse (REV)
oFixed frequency 1 (FF1), set to 20 Hz
Fault message via a potential-free contact (up to 230 V~) between terminals 13 and 14. Switching con-
ditions:
oON
No fault AND
START command (FWD or REV) present
oOFF
In case of fault: directly
After removal of the START command (FWD or REV). In case the motor ramps to
stop (P-05 = 1 = Default) the contact opens at speed zero.
Ramp times set to 5 s.

AP040092EN _DE1 Quick-Start-Guide www.eaton.eu Page 6
Environmental conditions
With the exception of DE1-34016…… all sizes of the Variable Speed Starter DE1 can be
used in the temperature range between -10 °C and +60 °C without any derating.
Derating for DE1-34016…. see manual MN040011EN.
VSS can be mounted on a mounting plate or on a top hat rail (DIN rail).
Please note that the devices DE1-121D4… and DE1-122D3…may have a max deviation of ± 5 ° from the vertical.
For all other DE1 devices a deviation of up to 90 ° (= horizontal mounting) is permitted.
In all situations described above a direct side by side mounting of
the Variable Speed Starters is permitted. This enables the use of
commoning links DILM12-XDSB0/3…5 for parallel supply of multiple
VSS and the use of a common protective device up to a max. current
of 30 A.
Details for group protection and branch protection in UL environ-
ment are given inside the manual MN04011EN.
High availability
During the conception phase a high attention was given to a failure-free operation and
the prevention of unintended trips. There are countermeasures to prevent tripping
due to overvoltage caused by regenerative operation of the motor, tripping at high
operating temperatures and tripping due to overcurrents from motors which are al-
ready spinning when the Variable Speed Starter is enabled.
If necessary, these functions can also be disabled. The Variable Speed Starter itself is
still protected in this case but trips may occur.

AP040092EN _DE1 Quick-Start-Guide www.eaton.eu Page 7
In default the Variable Speed Starter trips once a fault is detected and has to be reset. It is also possible to acti-
vate the function “Auto-Restart”, which resets the VSS automatically up to 9 times (number of Resets can be
selected) and restarts the device. This function may only be activated when an automatic restart doesn’t lead
to a dangerous situation for people and goods.
Overvoltage control
DE1 Variable Speed Starters have an internal algorithm, which prevents trips due to
overvoltage in case of regenerative braking of the motor. Output voltage and frequen-
cy are adjusted in a way that there is no energy flowing back to the VSS device.
Application examples:
Ramp down time set too short: the overvoltage control extends the ramp time automatically to avoid
regeneration.
The motor is driven by the load, e.g. washing machines and other applications with imbalance. To pre-
vent overvoltage trips the Variable Speed Starter increases its output voltage and frequency automati-
cally. The result is a small increase in speed which is acceptable in many applications.
This function can be disabled with P-31.
PWM regulation (Auto-Temperature-Management)
The temperature at the heatsink of the device depends on several factors, e.g. the
environmental temperature and the cooling conditions. In addition the motor current
and the switching frequency are important. In case a temperature close to the max.
limit is detected, the Variable Speed Starter DE1 reduces the switching frequency au-
tomatically, which leads to a reduction of the DE1 losses. In many cases this prevents a
trip because of overtemperature.
ATTENTION: If a sine wave filter is used at the output, the switching frequency has to be constant to avoid
resonances. In this case Auto-Temperature-Management has to be disabled with P-32.
DC-Braking
When enabling the Variable Speed Starter, a motor, which is already spinning, can
cause a high inrush current which is detected as a short circuit with the consequence
of a trip. This depends on certain conditions like speed, time of enabling….. An applica-
tion example is a fan which is mounted in a wind tunnel and which is driven by the
natural air flow.
To prevent a trip DE1 offers the possibility to inject DC current into the motor before
starting. This function results in a short time delay between start signal and start of the motor. This function is
not activated in default. If DC braking is required, the function can be activated. See further down in this Quick-
Start-Guide

AP040092EN _DE1 Quick-Start-Guide www.eaton.eu Page 8
Status LEDs
The LEDs on the front of the Variable Speed Starter indicate operating status and faults
Run (green)
oOFF = Fault or DE1 not supplied
oFlash every 2 s = Ready, no start signal (FWD/REV)
oON = RUN
Status (red)
oOFF = DE1 OK
oFlash every 0,5 s: Undervoltage e.g. during power up
oON = Fault
Fault Code (Red)

o2 x Flash + 2 s OFF external fault
o3 x Flash + 2 s OFF over voltage
o4 x Flash + 2 s OFF over current (motor protection)
o5 x Flash + 2 s OFF over temperature at the heatsink
o6…13 x Flash internal fault
Fault Code (yellow)
oDC braking active
Reset
After a fault message a reset is necessary to restart the Variable Speed Starter after elimination of the root
cause.
Reset is possible
By disconnecting the supply voltage at the terminals L1/N at DE1-12… respectively L1/L2/L3 at DE1-
34… and reapplying it
With a rising edge of the start signal (FWD / REV)
automatically, where the DE1 is configured accordingly (see „Startmode and Auto Reset“)
via Modbus or SWD, if used

AP040092EN _DE1 Quick-Start-Guide www.eaton.eu Page 9
Configuration module DXE-EXT-SET
DXE-EXT-SET is an optional module, which can be plugged onto the front of the
Variable Speed Starter. It is used for simple modification of selected parameters
without using a PC or keypad. All sizes of DE1 use the same module.
It can be plugged and unplugged when live. The module is not necessary to oper-
ate DE1 after a parameter change. It can be removed after use. The settings are
“stored mechanically” by the position of the switches and potentiometers.

AP040092EN _DE1 Quick-Start-Guide www.eaton.eu Page 11
Motor protection
The internal motor protection protects the motor against overload. In default the
motor protection is set to the device’s rated current. It can be set to values between
10 and 100 % of the rated current by using the potentiometer “I motor” on the con-
figuration module. If a keypad or the PC software DrivesConnect is used, the motor
protection is set with P-08.
An overload is detected by the Variable Speed Starter and when the protection set-
ting is exceeded the DE1 trips with an over current message. In default the Variable
Speed Starter is configured in a way, that the thermal memory is activated and the content will be stored even
when the unit is switched off. This means that the value is still present when restarting the VSS and the
memory is not reset. If a reset of the thermal memory is required by the application it can be configured by P-
33.
Depending on the configuration of the input terminals the
function „external fault“ (EXTFLT) is assigned to terminal 3.
This Input can also be used to connect a thermistor. Wiring see
picture on the left hand side.
A fault is detected when the resistance is greater than 3600
Ohm. A reset of the fault is possible when the resistance is
below 1600 Ohm and the motor has cooled down.
Application hint: DE1 is built according IEC/EN 61800-5-1 where it is required to have a reinforced insulation
between mains circuits and low voltage circuits. For that reason, a reinforced insulation between the thermis-
tors and the motor windings is required not to weaken the overall insulation system of the PDS (Power Drive
System).

Configuration of the control terminals
In default Variable Speed Starters are configured for terminal mode (P-12 = 0). The following information refers
to this mode only. Settings of P-12 different from zero may lead to other terminal configurations (see manual
MN040011EN).
There are 10 different terminal configurations which can be selected either with the selection switch Mode on
the configuration module or with parameter P-15.
Mode 0
Default
2 directions (FWD / REV)
Speed reference via potentiometer (0 … 10 V)
Fixed frequency FF1, default = 20 Hz. With High-
Signal at terminal 3 the reference changes from
the analog value at terminal 4 to fixed frequency 1
(P-21)
Mode 1
External fault
2 directions (FWD / REV)
Speed reference via potentiometer (0…10 V)
Terminal 3 is used as External Fault input. To op-
erate VSS a High Signal is necessary (Fail safe). If
the signal at terminal 3 is missing DE1 trips and an
external fault is indicated. It is also possible to
connect a thermistor to terminal 3. Details see
“motor protection”.
Mode 2
Fixed frequencies (1)

Full parameter access
In case access to additional parameters is needed, this can be achieved by using:
the optional keypad DX-KEY-LED (V1.2 and above)
the parameter software DrivesConnect. Free Download:
http://www.drive-support-studio.com/OTS/Eaton/downloads/deploy/drivesConnect.htm
the communication system SmartWire DT in connection with the option module DX-NET-SWD3
Modbus RTU
The Variable Speed Starter can be accessed via the RJ45 socket on front of the device. For handling details
please refer to the respective manuals and the DE1 manual MN040011EN.
Handling with DX-KEY-LED
Press OK for 2 s to access parameter level
The parameter used previously will be displayed.
Select parameter with and 
Press OK . Change values with and 
Press OK to acknowledge
Press OK for 2 s to leave parameter level.
Access to the extended parameter set (Level 2)
The parameters of the Variable Speed Starter DE1 are divided into two levels.
The standard parameter set, containing the 14 most common parameters (P-01 … P-14)
The extended parameter set (Level 2)
The extended parameter set can be accessed by entering a code in P-14. In default the code is 101. This code
can be modified by the user by changing parameter P-38.
P-14 equal to P-38 access to the extended parameter set
P-14 different to P-38 quit extended parameter set

AP040092EN _DE1 Quick-Start-Guide www.eaton.eu Page 17
Configuration of the analog input
In case an analog input is needed (P-15 = 0 / 1 / 3 / 8 / 9), this functionality is assigned to terminal 4.
A configuration of the analog input can be done as follows:
Voltage- or current input signal (P-16 = AI1 Signal Range)
o0 … 10 V
o0 … 20 mA
o4 … 20 mA, trips if signal is below 3 mA (wire break)
o4 … 20 mA, ramps to fixed frequency 1 if signal is below 3 mA (wire break)
Scaling (P-17 = AI1 Gain)
Inversion (P-18 = AI1 Invert)
oP-18 = 0 0 V = min frequency 10 V = max frequency
oP-18 = 1 0 V = max frequency 10 V = min frequency
Configuration of digital input 3 (terminal 3)
In case terminal 3 is configured to be used for an external fault signal (EXTFLT, P-15 = 1 / 3 / 5 / 7 / 9), it can be
used as „normal“ digital input or for the connection of a thermistor (see also: chapter “motor protection”). A
special configuration is not necessary.
The logic can be inverted with P-19 (DI3 Logic)
0 High = OK, Low = Fault (necessary for thermistor)
1 Low = OK, High = Fault

AP040092EN _DE1 Quick-Start-Guide www.eaton.eu Page 18
DC braking
Parameter P-25 defines the operation of the DC braking. In default DC braking is disabled. DC-Braking before
Start can be activated, to bring spinning motors to stand still before the Variable Speed Starter starts. This is to
prevent trips because of too high inrush currents (Fans).
The duration of the braking is set with P-26 (t-DCBrake@Stop). This time applies for a braking before start as
well as for one after a stop command.
The DC voltage during the braking period is set with P-27 (DCBrake Voltage) as a percentage of the motor’s
rated voltage (P-07). Higher values = higher braking torque
P-28 (f-DCBrake@Stop) defines the threshold at which DC braking after stop will be activated. The value is
given as output frequency in Hz. Before reaching the threshold the motor decelerates with the ramp set with P-
04. The Stop Mode (P-05) has to be set to “Ramping”.
In cases where Stop Mode is set to “Coasting” DC braking starts immediately after a stop command.
P-28 (f-DCBrake@Stop ) is ineffective.
During DC braking the LED “Fault code” appears yellow
Start-Mode and Auto Reset
The behavior of the Variable Speed Starter DE1 at start is selected with parameter P-30 (Default: Auto-0)
EdgE-r Following power on or reset DE1 will not start if a start signal (FWD/REV) is still present. To
start, a rising edge at FWD/REV is necessary.
Auto-0 Following a power on or reset DE1 will automatically start if a start signal (FWD/REV) is still
present.
Auto-1 … Auto-9 Following a trip, DE1 will make up to 9 attempts to restart automatically at 20 sec-
onds intervals. The number of restart attempts is counted and if DE1 doesn’t restart, it trips after the
final attempt. In this case reset has to be done manually. The counter of attempts can only be reset by
removing the power from the DE1 device.

AP040092EN _DE1 Quick-Start-Guide www.eaton.eu Page 19
Modbus
Variable Speed Starters DE1 can be connected to a Modbus network. In this case the following parameter set-
tings are necessary:
P-12 = 3 (ProcessDataAccess)
P-34 (PDP-Address) to be set to the DE1’s address in the Modbus network
P-35 (RS485-0 Baudrate) Setting of the baudrate
P-36 (Modbus RTU0 COM Timeout) Behavior at communication loss
Terminal 1 is used as hardware enable and requires a High signal to operate DE1 via Modbus. For additional
changes of the terminal configuration compared to the settings in default see manual MN040011EN.
SmartWire
When using the option module DX-NET-SWD3 Variable Speed Starters DE1 can communicate with the Smart-
Wire system. In this case the following parameter settings are necessary:
P-12 = 9 (ProcessDataAccess)
Terminal 1 is used as hardware enable and requires a High signal to operate DE1 via SmartWire. For additional
changes of the terminal configuration compared to the settings in default and for additional operating modes
see manual MN040011EN.

Determines the action taken by the Variable Speed Starter in the
event of the start signal (FWD/REV) being removed.
0 = Coasting. When the start signal is removed, DE1 output is imme-
diately disabled, and the motor will coast (freewheel) to stop.
1 = Ramping. When the start signal is removed, DE1 will ramp to
stop, with the rate controlled by “t-dec” (P-04).

When energy optimization is activated, the motor voltage is dynam-
ically varied, dependent on load. This results in reduced voltage
being applied to the motor on light load, significantly reduce energy
consumption. This mode of operation is less suitable for dynamic
applications where the load conditions can suddenly increase signif-
icantly.

Defines the Motor rated voltage, i.e. the voltage applied to the
motor when operating at “Motor Nom Frequency”.
When the output frequency is greater than the ”Motor Nom Fre-
quency” (P-09), the output voltage is controlled at the level set with
“Motor Nom Voltage” (P-07).

By setting the ”Motor Nom Current” in the VSS, the motor overload
protection is configured to match the motor rating.
When the measured motor current exceeds “Motor Nom Current”,
the decimal points on the optional display will flash to indicate an
overload condition.
If this condition persists, the VSS will eventually trip, displaying I.t-
trP, preventing thermal overload of the motor.

The rated frequency of the motor.
This is the frequency at which ”Motor Nom Voltage” is applied to
the motor.
Below this frequency, the applied motor voltage will be reduced.
Above this frequency the voltage remains limited to ”Motor Nom

The motor rated speed is set using this parameter.
If “Motor Nom Speed” = 0, the speed of the motor will be displayed
in Hz.
If “Motor Nom Speed” > 0, the speed related parameters (f-max, f-
min etc.) will be displayed in rpm.
The slip compensation is also activated, where the shaft speed of
the motor is maintained under varying load conditions by compen-
sating for the load-dependent slip of the motor.
If “Motor Nom Speed” = motor synchronous speed (e.g. 3000rpm
for a 2-pole 50Hz motor), the speed can be displayed in rpm without
activating the slip compensation.
