Wiring of motor temperature monitoring

The drive controller features 2 connections for motor temperature monitoring:
Terminals T1, T2 for connecting a PTC thermistor or thermal contact (NC contact).
ƒ
Pin X8/5 and X8/8 of the incremental encoder input (X8) for connecting a KTY
ƒ
thermal sensor.

Note!
Lenze system cables for motor feedback include additional cores for
temperature feedback. The cables are designed for wiring according to EMC.
