b5-15
n b5-16: PID Sleep Delay Time
Sets the delay time to activate or deactivate the PID Sleep function.
No.
b5-16
n b5-17: PID Accel/Decel Time
The PID acceleration/deceleration time is applied on the PID setpoint value.
As the normal acceleration times C1-oo are applied after the PID output, they reduce the responsiveness of the system and
can cause hunting or over- and undershooting 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 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. The setpoint must be entered via an analog input, pulse input, or MEMOBUS/
Modbus register 06H.
Setting 1: Enabled
Parameter b5-19 is used as PID setpoint.
n b5-19: PID Setpoint Value
Used to adjust the PID setpoint if parameter b5-18 = 1.
No.
b5-19
n 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: Hz
The setpoint and PID monitors are displayed in Hz with a resolution of 0.01 Hz.
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.
