Delayed disconnection in partial-load operation ("Sleep Mode")

Delayed disconnection in partial-load operation ("Sleep Mode")
Task:
If the drive remains below a minimum load threshold for a longer period of time, the drive
is to be switched off for saving energy. If the setpoint exceeds the minimum load
threshold, the drive is to start again.
Solution:
The GP function "Analog comparison" (
) serves to monitor the setpoint
speed. As soon as it falls below the set switch-off threshold, the switch-off delay starts.
After the set delay time has expired, the drive switches off itself.
The switch-off delay is implemented with the GP function "Binary delay element"
(
As soon as the setpoint exceeds the switch-off threshold again, the drive restarts.
