Appendix D Maximum Motor Cable Lengths for Kinetix 5700 Power Supplies
Regenerative Bus Supply
Configurations
2198-RPxxx regenerative bus supplies have limited maximum drive-to-motor
cable length when DC-bus regulation is enabled. However, the DC Bus can be
extended up to 70 m (230 ft) to remote clusters of Kinetix 5700 inverters. The
result is a shorter distance from the inverter to the motor and thus shorter
individual motor cable lengths.

(1) Corner-grounded and ungrounded input power can be used, but you must add an isolation transformer to the input power circuit to provide grounded-WYE power. Unbalanced, floating, or
ungrounded systems can cause additional stress to the motor. For more information on these input power source types, see Input Power Configurations for Kinetix 5700 Power Supplies
on page 129.
(2) Impedance grounded systems running in ground fault conditions, for prolonged periods of time, cause additional stress to the motor insulation and can cause premature motor failure.
