Setting 1: %
The setpoint and PID monitors are displayed as a percentage with a resolution of 0.01%.
Setting 2: r/min
The setpoint and PID monitors are displayed in r/min with a resolution of 1 r/min.
Setting 3: User Defined
The setpoint b5-19 and PID monitors U1-01/04 are displayed with the unit and resolution
defined by parameters b5-38 and b5-39.
■ b5-34: PID Output Lower Limit
Sets the minimum possible PID controller output as a percentage of the maximum output
frequency (E1-04). The lower limit is disabled when set to 0.00%
■ b5-35: PID Input Limit
Sets the maximum allowed PID input as a percentage of the maximum output frequency
(E4-01). Parameter b5-35 acts as a bipolar limit.
■ 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 the PID setpoint 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.
