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

Case b)
The temperature is monitored via the drive and
an external device.
S Temperature sensor via drive
S External temperature switch on 1FN1
S On 1FN3 with PTC resistors via
control unit
Case a)
The temperature is monitored
via the drive.
Case c)
The temperature is monitored
via an external device only.
