
b5-15: PID Sleep Function Start Level
Sets the level that triggers PID Sleep.
The drive goes into Sleep mode if the PID output or frequency reference is smaller than b5-15 for longer than the time set
in b5-16. It resumes the operation when the PID output or frequency reference is above b5-15 for longer than the time set
in b5-16.
No.
b5-15
<1> In AOLV/PM and CLV/PM control modes, the setting units and range are expressed as a percent (0.0 to 100.0%) instead of in Hz.

b5-16: PID Sleep Delay Time
Sets the delay time to activate or deactivate 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- are applied after the PID output, they reduce the responsiveness of the system
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 digital input programmed for "PID SFS cancel"
(H1- = 34).
No.
b5-17

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.

b5-19: PID Setpoint Value
Used as the PID setpoint if parameter b5-18 = 1.
No.
