i2t Calculation
Motor temperature monitoring:
No temperature sensor:
P131 = 0
Monitoring with KTY84:
P131 = 1
PTC monitoring:
P131 = 2
Monitoring with PT100:
P131 = 3
Monitoring with KTY83:
P131 = 4
Coupling via Src Motor Temp.:
P131 = 5
Temperature
evaluation
It is not possible to evaluate the motor temperature for
encoder evaluations that are not inserted in slot C.
