Error: Motor overtemp

[Hermes]

I'm getting "ERROR; MOTOR OVER TEMP" message on the LS600 LCD screen when I turn the system on, and then it halts.

According to the information from Sanyo Denki, both the 103H7123-1743 and the 103H7126-1745 stepper motors work with 24v DC but I get 48v from the leads in the X axis of the LS600. I attach a mapping of the readings on the 4 leads of each motor's connector, on the electronics rack.

I still haven't found the malfunctioning part.

Any suggestions will help.

Thank you
