Carrying out the functional test
1. Start drive
1. Start inverter: X3/DI1 = HIGH.
a) If the inverter is equipped with an integrated safety system: X1/SIA = HIGH and X1/SIB = HIGH.
2. Activate preset frequency setpoint 1 (20 Hz) as speed setpoint: X3/DI4 = HIGH.
The drive rotates with 20 Hz.
3. Optional: activate the function for the reversal of rotation direction.
a) X3/DI3 = HIGH.
The drive rotates with 20 Hz in the opposite direction.
b) Deactivate the function for the reversal of rotation direction again: X3/DI3 = LOW.

2. Stop drive
1. Deactivate preset frequency setpoint 1 again: X3/DI4 = LOW.
2. Stop inverter again: X3/DI1 = LOW.
The functional test is completed.
