electric shock!
When it is necessary to touch high voltages lines, disconnect the main power
supply and wait at least 5 minutes before servicing the drive.
Note!
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.
Before installing and operating EC-controller please read this instruction carefully!

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

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.
