13.1.5 Error message for the winding temperature
Possible cause Corrective action
The electrical connection to the temperature
sensor is faulty

Check resistance between the controller and the
temperature sensor in the STM and replace the
electrical connection, if necessary.
Temperature sensor defective

Check the resistance of the temperature sensor.

If the resistance exceeds 630 Ohms at room
temperature, the STM must be sent to SCHUNK with
a repair order.
Thermal motor overload

Reduce the load.

Mount the motor on heat-conducting materials to
dissipate excess motor heat.
Rotor is blocked mechanically

Check the mechanical components.

Check the evenness at the mounting surface (see
chapter 7.1, page 27)
Encoder signals are faulty;
encoder line shielding is not corrected.

Check the encoder's power supply.

Check the encoder signals and the shielding of the
encoder cable.
Motor overload;
overvoltage or undervoltage

Check the dimensioning.

Reduce the load.

Check the controller settings.

Check the output power supply.

13.2 MCS-12 controller
13.2.1 Software error messages
The MCS-12 controller indicates the error via the flashing red
LED. To determine the error cause, the MCS-12 controller must
be connected to the PC.

Consult the operating manual, MotionControl.pdf, and rectify
the error.
Note
In an error occurs, the STM is switched and the motor's phases
are bypassed, so that an active motion of the unit via the digital
inputs is not possible any more without acknowledging ("Error
Acknowledge") the error.
