5.2 b: Application
The PID acceleration/deceleration time can be canceled using a digital input programmed for "PID SFS cancel" (H1-oo =
34).
No.
b5-17
n b5-18: PID Setpoint Selection
Enables or disables parameter b5-19 for PID setpoint.
No.
b5-18
Setting 0: Disabled
Parameter b5-19 is not used as the PID setpoint.
Setting 1: Enabled
Parameter b5-19 is used as PID setpoint.
n b5-19: PID Setpoint Value
Used as the PID setpoint if parameter b5-18 = 1.
No.
b5-19
n b5-20: PID Setpoint Scaling
Determines the units for the PID Setpoint Value (b5-19) and monitors U5-01 and U5-04. The units for setting and display can
be changed with b5-20.
No.
b5-20
Setting 0: 0.01 Hz
The setpoint and PID monitors are displayed in Hz with a resolution of 0.01 Hz.
Setting 1: 0.01% (100.00%: Maximum PID Feedback)
The setpoint and PID monitors are displayed as a percentage with a resolution of 0.01%.
Setting 2: r/min (Set the Motor Poles)
The setpoint and PID monitors are displayed in r/min with a resolution of 1 r/min.
Setting 3: User Defined (Determined by b5-38 and b5-39)
Parameters b5-38 and b5-39 determine the units and resolution used to display the values the setpoint in b5-19, and PID
monitors U1-01 and U1-04.
n 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%
No.
b5-34
n b5-35: PID Input Limit
Sets the maximum allowed PID input as a percentage of the maximum output frequency (E1-04). Parameter b5-35 acts as a
bipolar limit.
No.
b5-35
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).
