C615: Sleep Mode Selection
When the sleep mode is selected, the inverter output is switched OFF, if the frequency reference (or
PID output) remains below the sleep mode enter frequency (C616) for the set time period (C617).
Sleep mode can be used with or without PID control.
C616: Sleep Mode Enter Frequency (Hz)
This is the frequency used to activate the sleep mode and turn off the inverter. This is the frequency at
which the drive will enter in sleep mode.
C617: Sleep Mode Active Delay (Sec)
The inverter output will be turned off if the frequency reference (or PID output) remains below sleep
mode enter frequency (C616) for the set sleep mode active delay time.
C618: Sleep Mode Wake Up Band (%)
This is to prevent from rapid on/off of the drive. This is set with respect to the max frequency (A103)
and used as hysteresis when leaving the sleep mode. The inverter will be turned on when the
frequency reference (or PID output) exceeds the sleep mode enter frequency (C617) + wake up band
(C618).
C619: Sleep Mode Leave Condition
This parameter defines the sleep mode leave condition. There are two conditions to wake up from the
sleep mode as below.
1. Freq Ref > C616 Sleep Mode Enter Freq + Wake Up Band
2. Freq Ref > A102 Min Freq + Wake Up Band
