It is the responsibility of the user or installer to ensure correct grounding and
protection in accordance with national and local standards.
1.1. Personal Safety
The [Start / Stop] input on the user interface panel of the EC drive does not disconnect the
drive from the AC line. Do not use it as a safety switch.
Do not remove the terminal lines from the motor and AC line supply while the EC drive is
connected to the active AC line. Ensure that the AC line supply has been disconnected and
wait 5 minutes before removing motor and AC lines.
The motor can be started by means of digital commands, bus commands, references or local
start command whenever the drive is connected to the AC line. Therefore, an unintended start
may occur anytime power is applied (fire mode, Start/Stop switch is on, etc.). Never service
the drive or equipment when power is applied to the drive.

2.3. Functions
Relay Error function: Controller is equipped with isolated Relay error function via relay
250VAC/3A, NO(17), COM(18) and NC(19).
Relay error function is always activated when error occurs.
Reset of processor is usually necessary after fixing the cause of error (depending on error
type –see error table –chapter 6. Troubleshooting)
AN1: Analog input 1 (terminals 9,10)–Input voltage from 0-10VDC. Electronics controls speed
linear from RPM min to RPM max. Maximal or minimal speed (inverted) is defined as input
voltage 9,5V ± 3%.
To start the motor via AN1 analog input, connect Start/Stop terminal pins (3 and 4) and FIRE
mode terminal pins (1 and 2) together. Make sure you are in mode 0 (speed) or mode 1
(torque).
For additional information see chapter 5. (INVENTO-S controller parameters)
Electrical parameters: Vinmax=12V, Zin=10kΩ, Resolution 10-bit, tolerance AN1±5%
Important: Wrong polarity at input AN1 could cause serious damage on the controller.
AN2: Analog input 2 (terminals 12, 13). Input Voltage from 0 –10VDC. This input is used as
output signal from sensor (usually temperature or pressure). Terminals 14 and 13 can be used
as power supply for the sensor and terminal 12 is used as measuring/process signal from
sensor.
For additional information see chapter 5. (INVENTO-S controller parameters)
Set RPM via potentiometer: Controller is be controlled by external potentiometer (4k7 to
47kΩ) connected to terminals (9 = GND), (10 = input) and (11 = +10V). If the direction of
rotary potentiometer is incorrect, change the wires on terminal (9) and (11).
Electrical parameters: Three-wire, Rpot=4k7 - 47kΩ, Zin = 10kΩ
Power supply 10VDC/10mA: Controller is equipped with 10VDC/10mA for power supply to an
external potentiometer. Power supplying other loads is not allowed. The 10 VDC supply is
galvanically isolated from the supply voltage, but has the same potential as the analogue and
digital inputs and outputs.
Electrical parameters: 10VDC +/- 5% (regulated); 10mA; Terminal number: 10.
Power supply 24VDC/40mA: Controller is equipped with 24VDC/40mA power supply for
external sensor connected to AN2, or for small external fan for cooling controller. The 24 VDC
supply is galvanically isolated from the supply voltage, but has the same potential as the
analogue and digital inputs and outputs.
Electrical parameters: 24VDC +/- 10% (not regulated); 50mA; Terminal number: 1, 4, 14.
Speed output: Controller is equipped with an Open Collector speed output signal for speed
monitoring, and offers some additional choices for process control.
For additional information see chapter 5. (INVENTO-S controller parameters)
Fire mode function: Controller is equipped with Fire mode function. In this case electronics
runs as emergency controlled unit, (for example: extract the smoke from a burning building),
with disabled protections and functions. Fire mode is activated by opening terminals 1 and 2
and enabling it via settable parameter.

DOMEL EC –Controller Invento S
V1.8, December 2015 Operating and installation Instructions 6
In Fire mode all errors are disabled, but power derating function is still active.
Electrical parameters: Operating voltage = 24V, Zin=10kΩ
Note!
Fire mode function is used only for protection in case of a burning
building, to extract the smoke from it. In normal conditions, fire mode
function is not used. In this case Domel is not responsible for damage
to the controller caused by improper use.
Star/Stop function: Controller is equipped with Start/Stop switch. If the controller has all
conditions for running, the motor starts when the terminal pins (3) and (4) are connected
together (switch ON). Reference is red from AN1 analog input. This function is enabled in
mode 0 (AN1 value = scaled speed reference), mode 1 (AN1 value = scaled torque reference)
and mode 4.
Electrical parameters: Operating voltage = 24V, Zin=10kΩ
LED indicators: LEDs are currently used to indicate code running on PIC processor and SPI
communication between processor in following manner:
RED LED blinking slow: Indicates code running on PIC processor
GREEN LED blinking fast: Indicates SPI communication between processors
This is normal state during controller operation and should be always present.
When controller is reset, green led stops blinking and only red led is active. This happens as
the PIC processor starts operating quickly after reset (red led blinking), but the SPI
communication between processor is not yet active (green led not blinking-either lit or not). As
soon as the communication between processors is established, green led starts blinking too,
usually after a few seconds after reset.
Modbus RTU 485 serial communication: Controller is equipped with Modbus RTU 485
communication. To connect controllers into chain use only shielded cables.
Fig.1:Shielded cable for ground connection between controllers is necessary

EC –Controller Invento S DOMEL
7 Operating and installation Instructions V1.8, december 2015
2.4. Protections
Thermal protection: Function that limits thermodynamic stresses on electronics by limiting
power. This function is a temperature limiter which reduces the output power, when
temperature on the controller reaches 95°C (is settable via Modbus as pderate_Tlow). The
power is decreased until it reaches a settable minimum value of torque.
Fig.2: Power derating with associated parameters
In the event that the temperature of controller is still rising the controller stops the motor.
When the temperature of controller falls below pderate_Tlow, controller automatically restarts.
Power derating function is enabled, but the overheating error is disabled in Fire mode.
Under and over voltage: Controller is equipped with under and over voltage protection.
Electronics shuts down when the main voltage is not in the required range.
Motor phase loss: Controller is equipped with power supply phase loss detection. In this case
controller stops the motor. Error is usually triggered at relatively high RPM, when the algorithm
can reliably detect 100Hz component in DC link.
Overcurrent protection: Controller is equipped with software and hardware phase
overcurrent protection. Software overcurrent error triggers when current exceeds fixed limit
(cannot be changed via modbus) and hardware overcurrent error triggers when current
exceeds limit, set by resistors on current measuring chipset .
Ground current fault: This protection triggers an error, when the sum of the motor currents is
more than 3A. Check the motor if it is damaged (cables, winding, etc.).
Parameters CRC: CRC check routine reports an error if reading/writing of parameters into
EEPROM is corrupted.
Drivers fault: This protection triggers an error, if high and low side of the motor phase
transistors are open at the same time.

DOMEL EC –Controller Invento S
V1.8, December 2015 Operating and installation Instructions 8
ADC offset fault: Error in ADC reading on current measurements or DC link voltages. Reset
of electronics is necessary.
SPI comm fault: Triggered when communication between processors is lost.
System error: Error in software(state machine error). Reset of the electronics is necessary.
Invento S Drive will not run if errors (non-autorestart) are present (see chapter 5).
Usually processor or Drive reset is required . Processor reset can be made via Modbus
( address 1 in coils tab ) or by disconnecting and reconnecting the main power supply
( hard reset ). As you disconnect the controller from power supply wait until LED
indicators stop flashing before reconnecting.
Note!
Heating the controller over the maximal temperature is not allowed.
Above 105°C (adjustable) controller stops the motor, and restarts it again
when the temperature of controller falls below 95°C (adjustable). However, if
the controller is overheating and motor was shutdown, disconnect power
supply (safety switch) and wait at least 20 minutes before you service them.
In case of controller overheating, it`s housing and components might still be
very hot and could cause serious damage to your skin.
If controller starts overheating over lower adjustable temperature limit during
running, it will limit the output power. In this case add small 24V/40mA fan on
controller or ensure air flow through the ribs. Fan can be supplied by power
from controller (page 15 –wiring diagram). Overheating problem appears in
the case of installation of the controller in the space without air flow. Avoid
installing controller on direct sunlight.

3. INSTALLATION AND CONNECTION OF INVENTO-S DRIVE
Use shield / armoured motor cable to comply with EMC emission specifications, and connect
this cable to both the decoupling plate and the motor metal.
Use only hard wire or fibre copper wire with ferrule (Fig 1).
Keep motor cables as short as possible to reduce the noise level and leakage currents. To
reduce the operating problems, use a shielded cable. Max length of cables is shown in the
table below.

DOMEL EC –Controller Invento S
V1.8, December 2015 Operating and installation Instructions 10
3.1. General installation
Correct and precise mounting of the controller is required to provide reliable and carefree operation.
The assembly should only be carried out by qualified personnel, because proper mounting, cooling
and sealing of controller is required. Mounting is permitted only at prescribed places. All positions
are allowed if conditions for solid attachment and adequate cooling are fulfilled (to prevent
overheating of electronic).
3.1.1. Mounting and sealing
We recommend horizontal (on table) or vertical (on wall, with cable glands pointing down)
attachment of the electronics. In horizontal installation we also recommend mounting on 2°-5°
angle with glands pointing down, for easier drainage of surface liquids. Suitable sealing for top
cover and all glands should be provided at mounting (whether there are cables or not). Space
between other objects and controller must be at least 20 mm (from the closest corner of the
electronics). When attaching to metal surfaces, the M5x15 screw (according to DIN912) with
spring washers is recommended. When attaching to non-metal materials the M5x70 screw for
walls is recommend.
3.1.2. Cooling
For smooth operation it is necessary to provide the required thermal conditions. We
recommend force cooling, with speed 1.5 m/s of fresh cooling air, through the cooling ribs,
although is possible to have cooling only with natural convection1. By cooling with natural
convection, the user should ensure at least 1 m of space over the highest cooling rib and also
controller may not be located in an enclosed place or placed under direct sunlight.
Note: Cooling exclusively with natural convection decreases lifetime of electronics.

3.2. Connection instructions
a) Remove the Top cover of the terminal strips and unscrew the cable glands No3 (Fig.2). Insert
the motor cable through and mount the shield and connect the motor wires (U, V, W) to the
corresponding terminal. Motor PE wire (yellow-green wire) can be connected to the terminal
or screwed directly to the housing (Fig.2).
b) Fig.3 shows how to properly connect wire to the motor and mains terminals
c) Remove the sealing insert for sealing cable gland No1 and insert the communication cable.
Mount the cable and carefully (fig. 4) connect desired user interface terminals. Screw the
cable gland for optimum IP protection.
d) If Fault Relay function is needed then unscrew the cable glands No2. Connect the wires for
Relay Fault to the corresponding terminals. Tighten the cable gland for optimum IP
protection. Do not use the same cable gland for Relay Fault as for communication cable. It
could cause operating problems and unstable control signals due to noise.
e) Connect mains supply wires to the corresponding terminals in the following sequence:
(1) PE ; (2) L1 ; (3) L2; (4) L3 ;
f) If there is some blank cable gland, fill it with sealing inserts.
g) Check all connections again.
h) Carefully replace the Top cover back and connect the Power supply voltage.

Fig.5: How to Connect / Disconnect wire
Warning!
Use cable with minimal 7mm thickness. All unused glands must be closed.
Use appropriate sealing insert or appropriate stopper if cable is not used.
Top cover must be screwed with 1Nm of torque and all screws must be used.
These actions must be done to avoid exceesive humidity and possible fluid
leaks inside the controller.
Fig.6:How to operate correctly with terminal strips
Warning!
Press only 0,5kg max, 4mm deep at angle 45° with 3mm slot
screwdriver. Damaged terminal strips can cause serious damage on
the Controller and fatal injury from electric shock.
Note!
It is the responsibility of the user or installer to ensure correct
grounding and protection in accordance with national and local
standards.

13 Operating and installation Instructions V1.8, december 2015
3.3. Grounding
Comply with the following at installation:
Safety grounding: The drive has a high leakage current and must be grounded
properly for safety. Follow all local safety regulations.
High frequency grounding: Keep grounding cables as short as possible.
Connect all grounds to ensure the lowest possible conductor impedance. The lowest possible
conductor impedance is achieved by keeping the conductor as short as possible and by
grounding with the greatest possible surface area.
3.4. Installation to minimize EMI / RFI
To minimize conducted and radiated high frequency emissions :
Use only shielded/armoured motor cables and shielded/armoured control
cables.
Connect the shield to ground at both ends.
Use attached cable clamps for installation to provide shielding at high
frequencies.
Fig.7a: Correct grounding Fig.7b: Incorrect grounding
Correct grounding to minimize EMI/RFI emissions: Fig.7a
Control cables and cables for serial communication must be attached with cable clamps at both ends
to ensure maximum possible electrical contact.
Incorrect grounding: Fig.7b
Do not use screen ends that are twisted together –that will increase screen impendence at higher
frequencies.
3.5. Connecting the electrical system
Check whether the data on the type plate matches with the connection data.
Before connecting the device, ensure that supply voltage matches operating voltage of the
device.
Only use cables that are configured for the current according to the specification on the type
plate.

4. MODBUS RTU
4.1. MODBUS overview
The MODBUS RTU protocol is based on the built-in RS-485 (EIA-485) interface. RS-485 is a two-wire
bus-interface that allows multi-drop network topology i.e. nodes can be connected as a bus (daisy
chain), or via drop cables from a common trunk line.
Domel’s Invento S drives uses the two-wire system where the communication between master and
slave is half-duplex, i.e. it cannot transmit and receive at the same time. Each signal uses one twisted-
pair line —two wires twisted around themselves. The signal on one wire is ideally the exact opposite
of the signal on the second wire. Since RS-485 is a multipoint communication system, all devices are
connected to the single twisted-pair cable.
The Modbus RTU uses master/slave architecture, where each slave device has its unique address
and responds only to packets addressed to this device. The packets are generated by the master
(Controller), which periodically polls all connected slave devices. Data travels over the single line in
both directions.
One or more EC drives can be connected to a control (or master) using the RS-485 standardized
interface. Maximal number of IFT EC Drives connected to the network is 32. If more than one
frequency converter is connected to a master, use parallel connections. Modbus user interface uses
terminals (5) (6) in parallel connection with (7) (8) (see page 17).

SPEED reference is calculated as: (current reference value can be seen in input register tab at address 28)
●
TORQUE reference is calculated as: (current reference value can be seen in input register tab at address 17
●
AN2 : Sets reference for AN2 feedback sensor signal. Reference value can be seen in input register tab at
address 13
1 0 1 * 3 0
Sets the direction of rotation of the motor shaft.
0: (CCW) CounterClockWise direction
1: (CW) Clockwise direction
Direction cannot be changed during motor run.
2 0 5000 RPM 2 & 3 motor dep.
Sets the minimal setable RPM reference. Parameter uses value on level 3 as minimum value for level 2. Controller uses
level 2 value for operation. (level 3 minRPM = 200 => level 2 minRPM = 200+)
3 0 5000 RPM 2 & 3 motor dep.
Sets the maximal setable RPM reference. Parameter uses value on level 3 as maximum value for level 2. Controller uses
level 2 value for operation.
RPM reference can be set between minimal RPM and maximal RPM limits defined in level 2. Level 3 values are just for
limiting level 2 values.
4 1 50 RPM 2 30
Sets maximum diference between actual and reference (ramp) value.
5 1 1000 * 2 350
This parameter affects motor acceleration, by affecting ramp value in relation to difference between the actual speed
and reference. Motor accelerates faster if gap between actual and reference speed is bigger.
6 1 50 RPM 2 20
Sets maximum diference between actual and reference (ramp) value, when AN2 input is active.
7 1 1000 * 2 100
This parameter is used for ramp calculation when AN2 sensor signal is used. It directly regulates AN2 input without any
PID controllers. User sets this value depending on application. Higher values are for fast processess (pressure) and lower
for slow processess (thermodynamics)
8 0 32767 * 1 *
This parameter is used for setting access levels, restoring to factory settings, reading/writing to EEPROM.
0: Enter level 1, most parameters are locked
1: Enter level 2, user can change parameters requiring level 2 and level 1 access
31114:
Enter level 3, user can change most of the parameters
10000: store values to EEPROM at current level
10001: restore values from EEPROM (last saved values)
10002: restore default values from one level above current
10011: restore level 3 parameters from factory settings
10020: set previous value as password (will not be accepted if password matches 10000.11000 or access level is<1)
6+6666: restore all parameters from factory settings
9 2 147 * 2 80
Sets modbus address.
10 032767 * 1 0
Selects current controller operation mode. Available modes are:
0:
AN1 Speed mode: Speed reference is set as:
