Note 1
Input power enters enclosure from metal conduit. This
eliminates the need for shielded input power cable.
Note 2
Single point ground. A bus bar (ground bus) is an
excellent way to achieve this.
Note 3
High frequency ground between non-conductive back
panel and enclosure. Also, a high frequency ground is
required between the enclosure and earth ground.
Note 4
Bonding of the motor cables. The use of armored
(screened) motor cables that are bonded as close to
the drive as possible is essential for CE compliance
and strongly recommended to better the overall
performance and reliability of the system.
Note 5
Screened and bonded feedback cabling is recommended for increased immunity
and lower risk of radiation. Since the motor cable and feedback cable are in close
proximity at the motor, this feedback cable bonding is necessary. Also, separate
the feedback and motor cables as much as possible. This decreases the chances
of the feedback signals getting corrupted.
Note 6
Control signals (I/O) should be kept separate from all power and motor cables.
Keep all control wiring as short as possible and use screened wire. A separation
distance of 20cm (8in) is sufficient in most cases. Where control cables must
cross power cables, they should cross at a 90º angle.
Note 9
Input power wires should be kept clear of I/O and signal wires.
Note 8
Where motor cables exit enclosure, keep in separate wire-way or conduit from
feedback and other control wiring. A separation distance of 20 cm. or 8 in. is
sufficient.
Note 7
Connect safety grounds to filters. This is critical to keep ground currents from
causing personal injury.
