Switching on

After switching on: Wait a second and then set the inputs.

ENABLE

Set ENABLE input. The first time ENABLE is set after the switch-on procedure, the drive conducts a

commutation angle search (duration: up to 2 seconds). Wait for Ready output.

Start homing

Start homing via REF input.

Homing run ended

Following successful completion of the homing run the Referenced output is set.

Reset REF

The REF input may only be reset after successful completion of the homing run.
