5.7.6 Motor connection

 Note!

ƒ Fusing the motor cable is not required.

ƒ The drive controller features 2 connections for motor

temperature monitoring:

– Terminals T1, T2 for connecting a PTC thermistor or thermal

contact (NC contact).

– Pins X8/5 and X8/8 of the incremental encoder input (X8) for

connecting a KTY thermal sensor.

Wire T1, T2 only if the motor is equipped with a PTC thermistor or thermal

contact (NC contact).

ƒ An "open" cable acts like an antenna and can cause faults on the drive

controller.

 Danger!

ƒ All control terminals only have basic insulation (single

isolating distance) after connecting a PTC thermistor or a

thermal contact.

ƒ Protection against accidental contact in case of a defective

isolating distance is only guaranteed through external

measures, e.g. double insulation.
