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