2.
Open the main contactor of the drive with S11.
3.
Switch the motor power supply from the drive to direct-on-line with S40.
4. Wait for 10 seconds to allow the motor magnetization to dissipate.
5. Start the motor with S41.

Switching the motor power supply from direct-on-line to drive
1.
Stop the motor with S42.
2.
Switch the motor power supply from direct-on-line to the drive with S40.
3.
Close the main contactor of the drive with switch S11 (-> turn to position ST
for two seconds and leave to position 1).
4. Start the drive and the motor with the drive control panel start key (drive in
the local control mode) or the external start signal (drive in the remote control
mode).
Protecting the contacts of relay outputs
Inductive loads (relays, contactors, motors) cause voltage transients when switched
off.
Install the protective component as close to the inductive load as possible. Do not
install protective components at the relay outputs.
