Operation
WARNING
For safety reasons, at power on or after a reset due to an alarm, the inverter is factory-preset not to start even with run control
in active state. To start the motor, you should set the control first to OFF and then to ON (this safety precaution can be
intentionally cancelled through b-03 parameter).
Turning on
• • • • •
The inverter is not provided with an ON/OFF switch. This operation is performed by appliying the mains voltage. After voltage
application, the inverter performs a test.
If an error is encountered during this test, the display will show the message C Err
The display, consisting of four 7-segment digits, shows both letters and numbers. When turned on, it shows the output

The inverter is factory-preset to control three-phase asynchronous motors which operate with voltages and currents having
values corresponding to the inverter size.

Run
1 - Connect a 4.7 kOhm potentiometer for the speed reference(terminals 13,14,15 )
2 - Power supply the digital inputs ( terminal 5) with +24V. If the inputs have not to be isolated, it is possible to use
the power supply available on the terminal 6.
3 - Connect two contacts for forward and backward run control (terminals 2, 1, and 7/8 ) as shown on page 6.
4 - Close the run contact to start the motor . The motor is started at the frequency selected through the preset
ramp (default P-05= 5 seconds).
WARNING
• • • • •
Stop
To stop the motor, act as follows:
- Disable the run control. In this way, the motor is stopped with factory-preset ramp (P-06= 5 seconds from max. frequency
to 0 Hz).
- Or set to zero the speed reference potentiometer, so that the user has control over the motor stop.
Caution: in this case the motor, even though it is stopped, is still under voltage.
• • • • •
The motor does not start
If after enabling the run control, the motor does not start, first check that the connections shown on the previous pages have
been performed, then check that the factory-preset parameters meet the motor characteristics.
The parameter check is performed by using the keypad: press the M key until the P P P P P menu appears , then, throung the ⇑, ⇑, ⇑, ⇑, ⇑,
⇓ ⇓ ⇓ ⇓ ⇓ keys select the code of the parameter with the value to be checked and press the E key to read its value. The data of
the motor rating characteristics are important; they can be set via the parameters P-01, P-02, P-09, P-11, P-12.

Caption of the function leds mounted behind the front cover
Before turning the inverter on, make sure the cover is locked in position. After each turning
off, wait 3 minutes before opening the unit so as to allow the capacitors to discharge.
If the factory - preset values should be modified to adapt the inverter to the application, it can
be made through the control panel where the actual values can be displayed, then modified, and
then permanently stored.
In case it is needed, the default values can be reset via the C02 function
