● Yes: The "LOCAL" or "REMOTE" operating state is saved when the power supply is
switched off and restored when the power supply is switched back on.
● No: The "LOCAL" or "REMOTE" operating state is not saved. "REMOTE" is activated
when the power supply is switched on.

external sources (PROFIBUS, customer terminal strip, NAMUR terminal strip).

the drive is switched off and the setpoint is set to 0.
