272 C-AXIS MOTOR OVERHEAT - Servo motor overheat. The temperature sensor in the motor indicates over 150° F. This can be caused by an extended overload of the motor such as leaving the slide at the stops for several minutes.

[KenFoulks]

The thermal sensor in the motor is indicating that is open. Either the sensor is bad, parameter 176 bit 14 could be set to a 0, or maybe a cable is not sending to the mocon. In any case it is better to contact the local dealer for assistance in solving this issue.

What is "C" axis on a VF2??? My machine uses "A" axis... I've even heard of "B" axis but what is "C" Axis on a vertical mill?

[miljnor]

I believe the C axis is the tool holder so probably the rotation motor but I've always had problems with the in and out motor.....or if its a sidemount disregard what i say.
