The 'PHR' parameter is to detect the phase sequence. Forward or reverse.
If the PHR is set for forward, but the wiring to the motor is reversed, the soft starter will trip on phase sequence fault.
If the PHR is set for reverse, but the wiring to the motor is forward, the soft starter will trip on phase sequence fault.
In case, an inside delta connection and set the dLtA to dLt (the soft starter is connected Inside delta connection), PHr is forced to 123.
In this case, PHr value is not used and is not relevant.
