How are the
The signal leads for motor temperature monitoring on 1FN motors are not
installed in the encoder cable, but in the motor power cable. In order to sense
temperature
the winding temperature of the drive, the temperature sensor signal leads must
sensors
be looped into the encoder cable (temperature sensor coupling lead).
