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.

n 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.
b5-40 Frequency Reference Monitor Content During PID
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 b5-46: PID Setpoint Monitor Unit Selection
Sets the HOA keypad display units in U5-01 and U5-04 when b5-20 is set to 3.
No.

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), this parameter has no effect and the PID output will not be limited
(same as b5-11 = 1).
No.
b5-47
Setting 0: Reverse Disabled
Negative PID output will be limited to 0 and the drive output will be stopped.
