n b5-47: PID Output Reverse Selection 2
Determines whether a negative PID output reverses the direction of drive operation. When the PID function is used to trim
the frequency reference (b5-01 = 3 or 4), this parameter has no effect and the PID output will not be limited
(same as b5-11 = 1).
No.
b5-47
Setting 0: 0 Limit (Reverse Disabled)
Negative PID output will be limited to 0 and the drive output will be stopped.
Setting 1: Reverse Enabled
Negative PID output will cause the drive to run in the opposite direction.
