b5-38, b5-39: PID Setpoint User Display, PID Setpoint Display Digits
When parameter b5-20 is set to 3, parameters b5-38 and b5-39 set a user-defined display for the PID setpoint (b5-19) and PID
feedback monitors (U5-01, U5-04).
Parameter b5-38 determines the display value when the maximum frequency is output and parameter b5-39 determines the
number of digits. The setting value is equal to the number of decimal places.

b5-40: Frequency Reference Monitor Content During PID
Sets the content of the frequency reference monitor display (U1-01) when PID control is active.
No. Name Setting Range Default
b5-40 Frequency Reference Monitor Content During PID 0, 1 0
Setting 0: Frequency Reference after PID
Monitor U1-01 displays the frequency reference increased or reduced for the PID output.
Setting 1: Frequency Reference
Monitor U1-01 displays the frequency reference value.
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. Name Setting Range Default
b5-47 PID Output Reverse Selection 2 0, 1 1
Setting 0: 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.
