5.5.1 Wiring of motor temperature monitoring
The drive controller features 2 connections for motor temperature monitoring:
ƒ 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
thermal sensor.
Incremental encoder input (X8) Terminals T1, T2
Connectable thermal
sensor Linear thermal sensor (KTY) l PTC thermistor
– PTC thermistor with defined
operating temperature (to
DIN 44081 and DIN 44082)
l Thermal contact (NC contact)
– Temperature switch as NC contact
Tripping point l Warning: Adjustable
l Error (TRIP): Fixed at 150 °C
l Fixed, (depending on the PTC/thermal
contact)
l PTC: R J > 1600 W
l Configurable as warning or error
(TRIP)
Notes l Monitoring is not active in the Lenze
setting.
l The KTY is monitored with regard to
interruption and short circuit.
l Monitoring is not active in the Lenze
setting.
l If you do not use a Lenze motor, we
recommend a PTC thermistor up to
150°C.

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