Cause : Motor overtemperature comes when the measured motor temperature or the temperature of the motor temperature model 2 has exceeded the alarm threshold (p0604).
The response parameterized in p0610 becomes active. PTC or bimetallic NC contact: The response threshold of 1650 Ohm was exceeded or the NC contact opened.
Alarm value (r2124, interpret decimal):
11: No output current reduction.
12: Output current reduction active.

- check the motor load.
- check the motor ambient temperature.
- check KTY84.
- check overtemperatures of the motor temperature model 2 (p0626 ... p0628).
