Cable shielding
The following information is not required for CE compliance of a
and grounding
single axis installation. When planning a multi-axis installation, or
if extra high frequency noise reduction is required, Pacific
Scientific suggests:
• In addition to the cable requirements given in this manual the
motor and signal interface cables should have a braided shield
which can be grounded to reduce high frequency disturbances.
• The motor cable shield must be grounded near the drive with a
suitable high frequency ground. Such a ground connection is
made by removing the cable's outer insulation, to expose the
braided shield, then clamping the exposed braid to a
conductive surface of the machine chassis. If the chassis is
painted or coated with another nonconductive coating, remove
the coating from the clamping location prior to clamping the
shield. It is important that the clamp chosen be conductive and
provide a full 360 degree connection.
