Power-Off Mode (Pn.44)
The parameter Power-Off-Mode (Pn.44) switches on the function and determines the basic behaviour:
Pn.44: Power off mode
Bit Meaning Value Explanation
0 Power off / activation
0: off Power-off function deactivated
1: on Power-off function activated
1 Start voltage
0: automatically Auto determination of the start voltage
2: xed level (Pn.45) Preset of start voltage with Pn.45
2
Initial jump (only v/f -cha-
racteristic)
0: from the slip
Determination of the initial jump from
the calculated slip
4: from the load
Determination of the initial jump from
the load factor
