Wiring of motor temperature monitoring

4.5.1 Wiring of motor temperature monitoring
The controller provides two inputs for connecting a thermal sensor. Depending on the type
used the thermal sensor must be either connected to the incremental encoder input (X8)
or to the terminals T1, T2.

Incremental encoder input (X8)
Linear thermal sensor (KTY)
Warning: Adjustable
Error (TRIP): Fixed at 150 °C
Monitoring is not active in the Lenze
setting.
The KTY is monitored with regard to
interruption and short circuit.
Note!
Lenze system cables for Lenze motors already include the cable for
temperature feedback. The cables are designed for wiring according to EMC.
If you prepare your own cables, the cables must always be separated from the
motor cable.

PTC thermistor
– PTC thermistor with defined
operating temperature (to
DIN 44081 and DIN 44082)
Thermal contact (NC contact)
– Temperature switch as NC contact
Fixed, (depending on the PTC/thermal
contact)
PTC: R 1600
ϑ > Ω
Configurable as warning or error
(TRIP)
Monitoring is not active in the Lenze
setting.
If you do not use a Lenze motor, we
recommend a PTC thermistor up to
150°C.
