2.2 b: Application
b5-16: PID Sleep Delay Time
■
Sets the delay time for activation or deactivation of the PID Sleep function.
No.
b5-16
b5-17: PID Accel/Decel Time
■
The PID acceleration/deceleration time is applied on the PID setpoint value.
As the normal acceleration times C1-
and can cause hunting or overshoot and undershoot when the setpoint changes quickly. Using the PID acceleration/
deceleration time instead helps to avoid such problems.
The PID acceleration/deceleration time can be canceled using a contact input programmed for "PID SFS cancel" (H1-
= 34).
No.
b5-17
b5-18: PID Setpoint Selection
■
Enables or disables parameter b5-19 for the PID setpoint.
No.
b5-18
Setting 0: Disabled
Parameter b5-19 is not used as the PID setpoint.
Setting1: Enabled
Parameter b5-19 is used as the PID setpoint.
b5-19: PID Setpoint Value
■
Used as the PID setpoint if parameter b5-18 = 1.
No.
b5-19
b5-20: PID Setpoint Scaling
■
Determines the units that the PID setpoint (b5-19) is set in and displayed. Also determines the units for monitors U5-01
and U5-04.
No.
b5-20
Setting 0: 0.01 Hz units
The setpoint and PID monitors are displayed in Hz with a resolution of 0.01 Hz.
Setting 1: 0.01% units (100% = max. output frequency)
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
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.
