Motor temperature
January 2012
To measure the motor temperature, a KTY 84 must be connected at pins 13
and 25 of X15 to X20, X80 to X83. 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.
Appropriate measures can be taken before the motor reaches the maximum
temperature.
Module 9165 Read the temperature of the drive motor
The module provides the temperature of a drive motor controlled by the
integral current controller in degrees Celsius.
Constraints:
The measuring range is 0 to 255 °C.
For non-existing axes the value 0 °C is read.
The temperature value is measured every 5 seconds.
An axis that is not configured as "active", or an axis that was set to the
"deactivated axis" activation status (e.g. with Module 9226 or 9418), is
treated as if it were not present.
