Motor Cable Length; Ground Connection; Motor Cable - Parker MGV Series Technical Manual

3.7.3.

Motor cable length

For motors which present low inductance values or low resistance values, the own cable
inductance, respectively own resistance, in case of large cable length can greatly reduce
the maximum speed or/and the maximum power of the motor. Please contact Parker for
further information.
Caution: It might be necessary to fit a filter at the servo-drive output if the
length of the cable exceeds 25 m. Consult us.

3.7.4. Ground connection

DANGER:
Consult the local regulations to choose the right cross section and to know
the resistance limits to check ground continuity between frame and ground
wire.
3.7.5.

Motor cable

The electrical connection on MGV motor is realized by high performance cable. The motor
cable section depends on the motor current level. Please refer to the outline drawing to
know the cross section (depending of torque/speed characteristics letter code).
Caution: The motor cables are designed for high current density, so cable
surface can reach or exceed 100°C.
Caution: The wiring must comply with the drive commissioning manual and
with the recommended cables.
Caution: Section motor cable is lower than commissioning section cable
between motor and drive due to high performance motor cable design. Don't
use the same cable section than the motor ones.
For the safety, you need to connect stator to the ground.
