PowerFlex 700S Drives with Phase II Control
Other types of shielded cable are available, but the selection of these types may limit the allowable cable length.
Particularly, some of the newer cables twist 4 conductors of THHN wire and wrap them tightly with a foil shield. This
construction can greatly increase the cable charging current required and reduce the overall drive performance. Unless
specified in the individual distance tables as tested with the drive, these cables are not recommended and their
performance against the lead length limits supplied is not known.
Maximum Motor Cable Lengths
• For the Terminator, the maximum cable length is 182.9 meters (600 feet) for 400/480/600V drives (not 690V).
The PWM frequency must be 2 kHz. The 1204-TFA1 can be used only on low HP (5 HP and below), while the
1204-TFB2 can be used from 2…800 HP.
• 1204 Reflected Wave Reduction Device (all motor insulation classes):
• 1204-RWR2-09
2 kHz: 182.9 m (600 ft.) at 400/480V and 121.9 m (400 ft.) at 600V.
4 kHz: 91.4 m (300 ft.) at 400/480V and 61.0 m (200 ft.) at 600V.
• 1204-RWC-17
2 kHz: 365.8 m (1200 ft.) at 400/480/600V.
4 kHz: 243.8 m (800 ft.) at 400/480V and 121.9 m (400 ft.) at 600V.
For both devices, power dissipation in the damping resistor limits maximum cable length.
The 1321-RWR is a complete reflected wave reduction solution available for many of the PowerFlex drives. If
available, a 1321-RWR catalog number will be indicated in the “Reactor/RWR” column. When not available, use
the reactor and resistor information that is provided to build a solution.
