Y2: PID Sleep and Protection

Sleep Function
The Sleep Function uses the monitor data set in Y2-01 [Sleep Level Type] to know if the drive is necessary in the
system and turn off the drive.
This function helps to save the energy and prevent the deterioration on the motor.
Sleep Activation Level and Sleep Level
• Sleep Activation Level:
This level sets when the Sleep Function should start operation. You can use Y2-04 [Sleep Activation Level] or
Minimum Speed (the largest value from d2-02, Y1-06, and Y4-12) to set this level.
When the output frequency increases to more than the Sleep Activation Level, the Sleep Function will start to
monitor the system.
• Sleep Level:
This is the level that the drive uses to go to sleep (stop). You can use Y2-02 [Sleep Level] or Minimum Speed to set
this level.
