b5-15: PID Sleep Function Start Level
Sets the level that triggers PID Sleep.
The drive goes into Sleep mode if the PID o
utput 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.
b5-16: PID Sleep Delay Time
Sets the delay time to activate or deactivate the PID Sleep function.
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 re
duce 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).
b5-18: PID Setpoint Selection
Enables or disables parameter b5-19 for PID setpoint.
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. Name Setting Range Default
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.
