8.5 Over temperature protection
8.5.1 Motor over temperature protection
Normally temperature switch will be installed inside motor to detect if the temperature is too high. Over
temperature signal can be connected to the servo drive to protect motor. The default input pin of motor
over temperature protection is I5. (I5 is on feedback connector CN3.) Temperature switch is usually
normally-closed. When temperature is within normal range, temperature switch is closed. When
temperature is too high, temperature switch is open. As temperature switch is activated, error message
“Motor over temperature sensor activated” appears. Then the servo drive executes emergency stop
procedure and disables the motor.
8.5.2 Software over temperature protection
In addition to motor over temperature protection, D1 servo drive is able to estimate motor temperature via
software. The estimated temperature is obtained by evaluating the current output from the servo drive. If
the estimated temperature reaches the threshold in the servo drive, error message “Soft-thermal
threshold reached” appears. Then the servo drive executes emergency stop procedure and disables the
motor. Select Soft-thermal accumulator in Quick view to check the current estimated temperature.
8.5.3 Servo drive over temperature protection
D1 servo drive is able to detect servo drive over temperature. When the temperature of the servo drive
reaches 80
o
C, error message “Amplifier over temperature” appears and the motor is stopped. Select
Amplifier temperature in Quick view to check the current temperature of the servo drive.
