Hi Rich,
If we would like to stop the motor by 2 limit switch, the concept design is the motor turns on forward direction(PH = 0), rotates the shaft until hits a limit switch then motor stop ( water valve open) and then wait for PH signal(PH = 0) to control reverse direction, the motor turns on until hits another limit switch( water valve close), if I understand correctly I can not use EN function because when EN is low, this device can not control the direction, in this case can I use nSLEEP pin to stop the motor and wait for PH input to control the direction of the motor?
