4.2.3 Thermal motor protection
The motor temperature is monitored by two systems that are operated inde-
pendently of each other. The mounted temperature sensor and the drive-internal
temperature model ensure the best protection of motors against thermal over-
load.
The threshold values for motor temperature monitoring are contained in the en-
coder data memory and are read in and monitored automatically during the op-
eration with IndraDrive controllers. Threshold values for MS2N motors:
●
Motor-warning temperature (140°C)
●
Motor-disconnection temperature (145°C)
