7.7.3 Field Wire Connections
Control cables, input power cables and motor cables should be installed separately and
enough clearance should be left among the cables, especially when the cables are laid in
parallel and the cable length is over 50 metres. If the signal cables must be laid with the power
cables, they should be installed parallel to each other.
Generally, the control cables should be shielded cables and the shielding metal net must be
connected to the metal enclosure of the drive by cable clamps.
7.7.4 Grounding
Independent groundng poles (best) Shared grounding pole (good)
Shared earthing cable (not good)
Note:
1. In order to reduce the grounding resistance, flat cable should be used because the high
frequency impedance of flat cable is smaller than that of round cable with the same CSA.
2. If the grounding poles of different equipment in one system are connected together, then the
leakage current will be a noise source that may disturb the whole system. Therefore, the
drive’s grounding pole should be separated with the grounding pole of other equipment such
as audio equipment, sensors and PC, etc.
3. Grounding cables should be as far away from the I/O cables of the equipment that is
sensitive to noise, and also should be as short as possible.
