Actual signals and parameters 243
4023 PID SLEEP
LEVEL
Defines the start limit for the sleep function. If the motor
speed is below a set level (4023) longer than the sleep
delay (4024), the drive shifts to the sleeping mode: The
motor is stopped and the control panel shows alarm
message PID SLEEP.
Parameter 4022 SLEEP SELECTION must be set to
INTERNAL.
0.0 Hz
0.0…500.0 Hz Sleep start level 1 = 0.1 Hz
4024 PID SLEEP
DELAY
Defines the delay for the sleep start function. See parameter
4023 PID SLEEP LEVEL. When the motor speed falls below
the sleep level, the counter starts. When the motor speed
exceeds the sleep level, the counter is reset.
