n 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.
No. Name Setting Range Default
