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