Appendix A Motor Cable Length Restrictions Tables
In the tables in this section, a ‘ ● ’ in the available options columns indicates that
the drive rating can be used with an Allen-Bradley terminator (catalog numbers
1204-TFA1/1204-TFB2) and/or reflected wave reduction device with common
mode choke (catalog number 1204-RWC-17) or without choke (catalog number
1204-RWR2).
Follow these guidelines for terminators and reflected wave reduction devices:
• For the terminator, the maximum cable length is 182.9 m (600 ft) for
400/480/600V drives (not 690V). The PWM frequency must be 2 kHz.
Catalog number 1204-TFA1 can be used only on low Hp (5 Hp and
below), while catalog number 1204-TFB2 can be used from 2…800 Hp.
• 1204 reflected wave reduction device (all motor insulation classes):
–
Catalog number 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.
– Catalog number 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.
Catalog number 1321-RWR is a complete reflected wave reduction solution
available for many of the PowerFlex drives. If available, a 1321-RWR catalog
number is indicated in the Reactor/RWR column. When not available, use the
reactor and resistor information provided in the tables in this section to build a
solution.
For this Cat. No. Refer to this Publication
