In your picture, there is a fatal flaw in the connection of SLEEP. This is a logic pin. You must not pull it up to 24V from 10k. After reading the specification, there is a 100k ground resistance during work, so you should at least use it for pull-up. A 510k, otherwise this foot will hang directly. However, looking at the specification, it seems that there is no such 100k resistor during sleep, so I don't know if there is any risk.
