7.8.4 Connecting the Motor Protection
INPUT/OUTPUT: The thermal motor protection is evaluated via these connectors.
The drive amplifier supports evaluating the temperature monitoring integrated in the mo-
tor. The NTC/PTC behavior of the monitoring is defined in the software (motor parame-
ters). The controller is deactivated as soon as the critical motor temperature is reached.
The following sensor types are available: NTC, PTC, KTY84130, KTY83122 and
PT1000.

The temperature sensor must have an internal resistor between 250 Ω and 2 kΩ.
Note
If no motor temperature sensor is connected, the input must be connected with GND.
