Cable gland
NOTICE
Damage to the cable jacket
An excessively high tightening torque with a different cable jacket material will damage the
cable jacket.
When different cable jacket materials are used, apply a lower tightening torque.
For metal or plastic cable glands, please use the following tightening torques for direct
mounting. The O-ring cross-section is 2 mm.

Converter operation

Suitably shielded cables and EMC cable glands must be used to connect the motors.
The maximum length of the motor cables is 15 m (49 ft), see section AUTOHOTSPOT.
Permissible voltage stress
For drives with G115D and EMC-adequate connection, the motor windings are designed to
be converter-suitable (against partial discharge).
Bearing currents
Additional bearing currents due to steep voltage edges when switching. Make sure the drive
system is installed in accordance with EMC requirements.
Mechanical stress and grease lifetime
High speeds that exceed the rated speed and the resulting increased vibrations alter the
mechanical running smoothness and the bearings are subjected to increased stress. This
reduces the service life of the grease and bearings.
