Overtemperature protection
At a temperature of approx. 80 °C on the board (corresponds to 72-75 °C outside on
the rear motor cover), the power drive of the controller is switched off and output 3 is
switch on. After the controller is cooled and restarted, it operates normally again.
The following temperature test results illustrate the temperature behavior of different
Plug & Drive motors. 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: 100% (3.2 A)/150% (4 A)
•
Operation mode: full step speed mode, 25 rpm and 0 rpm
•
Operating environment: Binder FED 53 temperature cabinet, circulated air at 100%
fan speed
•
Ambient temperature: 45 °C (50 °C, 55 °C, 60 °C for the comparative
measurement)
•
Test motors: PD4-N5918X4204 and PD4-N5918L4204
•
Measurement point: rear of motors for power transistors, on the outside of the
housing
The following graphics show the temperature test results:
