How can I tell if my ATV61 or ATV71 drive is in sleep mode? (Low speed timeout active).

Issue:
Identify if an ATV61 or ATV71 drive is in sleep mode

Resolution:
A relay or logic output can not be configured to show this status.

In order to determine if the drive is in sleep mode, you will need to have a serial communication network connected to the drive.  Perform a read of parameter LRS3 (Logic address 3252 , 16#0CB4).  Bit 9 of this word will indicate whether the drive is asleep or awake.  If bit 9 is high, the drive is in sleep mode.  If low, the drive is in normal operation mode.

Also note that if the Low speed is set greater than 0Hz, the VFD status is RUN, and the VFD motor frequency is 0Hz, then the VFD is most likely in Sleep mode.
