Carry out a funconal 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. Acvate frequency preset 1 (20 Hz) as speed setpoint: X3/DI4 = HIGH.
The drive rotates with 20 Hz.
3. Oponal: Acvate reversal.
a) X3/DI3 = HIGH.
The drive rotates with 20 Hz in the opposite direcon.
b) Now deacvate reversal: X3/DI3 = LOW.
