6.14 Over temperature protection
Over temperature protection is to avoid motor coil burn-out caused by high internal temperature inside
motor. To use over temperature protection, thermal sensor (TS) must be installed inside the motor. If the
motor has been continuously used with current which exceeds its rated current or with heavy load, its
temperature becomes high. At this time, a signal will be output to the servo drive to immediately stop the
motor. Thermal sensor is usually installed on direct drive motor (DM) or linear motor (LM). To use over
temperature protection, Excellent Smart Cube (ESC) is required.

 If an external regenerative resistor is used at the rated load ratio, the resistor
temperature will rise to 200°C～300°C. Decrease the rated value before usage. For
information of the resistor load, please contact its manufacturer.
 For safety, it is suggested to use external regenerative resistor with thermoswitch.
