Issue:
Sleep/wake operation (low speed timeout) programmed on the ATV212 drives.
Product Line:
Altivar ATV212
Environment:
All
Cause:
Allows the drive to shut off after running at a preset low speed for a preset period of time.
Resolution:
The sleep/wake threshold is defined as LL + F391.
The time period to trigger sleep mode is F256.
If the drive operates at or below the threshold (LL + F391) for a period of time (F256), the drive will decelerate to a stop and flash LStP. It will remain stopped until the speed reference again exceeds the threshold (LL + F391). The drive will then accelerate to the new reference.
