Overtemperature protection At a temperature of approx. 80 °C on the board (corresponds to 65-72 °C outside on the rear cover), the power drive of the controller is switched off and the error bit is set (see object 1001h and 1003h). After the controller is cooled and the error is confirmed (see table for the controlword, "Fault reset"), it operates normally again. The following temperature test results illustrate the temperature behavior of this controller. However, the specific temperature behavior depends not only on the motor but also largely on the flanging and the heat transition at the flange, as well as on the convection in the machine. Therefore, we recommend always performing a long-term test in a realistic environment for applications with problematic levels of current and ambient temperature. Temperature tests were performed under the following conditions: Operating voltage: 24 V / 48 V DC Motor current: nominal current Operation mode: Full step speed mode, 30 rpm Operating environment: Thermo TEC Ambient temperature: 25 or 45 °C Measurement point: rear at power transistors, on the outside of the housing The following graphics show the temperature test results:
