Figure 1.22 PID Sleep Operation
Notes on using the PID Sleep function:
• The PID Sleep function is always active, even if PID control is disabled.
• The method the Sleep function uses to stop the motor is defined by parameter b1-03.
• The parameters necessary to set up the PID Sleep function are explained below.
■
b5-15: PID Sleep Level
Sets the level used for 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.
■
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 reduce the
responsiveness of the system and can cause hunting or over- and undershooting when the
