To measure the motor temperature, a KTY 84 must be connected at pins 13
and 25 of X15 to X20, X62 to X64 and at X60. The temperature value is
ascertained at least once per second. The maximum permissible motor
temperature is taken from the motor table.
As soon as the given temperature is exceeded, the blinking error message
MOTOR TEMPERATURE <AXIS> TOO HIGH appears and the drives are automatically
switched off.
Module 9165 Sampling the current motor temperature
Appropriate measures can be taken before the motor reaches the maximum
temperature.
