Protective functions
Here is an overview:
Parameter
Pn.44 Power off mode
Bit 0, 1, 3, 4, 5
Bit 2, 8
Bit 6, 7, 9
Pn.45 Power off start voltage
Pn.46 Power off auto st. level
Pn.47 Power off brake torque
Pn.48 Power off restart level
Pn.49 Power off start inp. sel.
Pn.50 Power off ref. DC voltage
Pn.51 Power off KP DC voltage
Pn.52 Power off restart delay
Pn.53 Power off KP
Pn.54 Power off KI
Pn.55 Power off KD
Pn.56 Power off jump factor
Pn.57 Power off KI DC voltage
Power-Off Mode (Pn.44)
The parameter Power-Off-Mode (Pn.44) switches on the function and determines the basic behaviour:
