Table 1.A Recommended Cable Design
Unshielded Cable
Properly designed multi-conductor cable can provide superior performance
in wet applications, significantly reduce voltage stress on wire insulation
and reduce cross coupling between drives.
The use of cables without shielding is generally acceptable for installations
where electrical noise created by the drive does not interfere with the
operation of other devices such as: communications cards, photoelectric
switches, weigh scales and others. Be certain the installation does not
require shielded cable to meet specific EMC standards for CE, C-Tick or
FCC. Cable specifications depend on the installation Type.
Type 1 & 2 Installation
Type 1 or 2 installation requires 3 phase conductors and a fully rated
individual ground conductor without or with brake leads. Refer to
for detailed information and specifications on these
installations.
