Determining the Maximum
Cable Length for Your System
Use the following tables to determine the maximum cable length for
your system.
The values shown are for nominal input voltage and a drive carrier
frequency of 2 kHz. If you plan to operate your system at carrier
frequencies above 2 kHz, refer to the heat dissipation table on page 3.
If you plan to operate your system above the levels listed in the heat
dissipation table, consult the factory.
If you are running at high-line conditions (nominal line + 10%),
multiply the values by 0.85.
1305 Drive Maximum Motor Cable Length Restrictions
Lengths are given in meters and (feet)
NR = Not Recommended.
Type A Motor Characteristics: No phase paper or misplaced phase paper, lower quality insulation systems, corona inception voltages between 850 and 1000 volts.
Type B Motor Characteristics: Properly placed phase paper, medium quality insulation systems, corona inception voltages between 1000 and 1200 volts.
1329R/L Motors:
These AC variable speed motors are “Power Matched” for use with Allen-Bradley drives. Each motor is energy efficient and designed
to meet or exceed the requirements of the Federal Energy Act of 1992. All 1329R/L motors are optimized for variable speed operation
and include premium inverter grade insulation systems which meet or exceed NEMA MG1. Part 31.40.4.2.

For applications/ installations using new
motors, no restrictions in lead length due to
voltage reflection are necessary. You should
observe standard practices for voltage drop,
cable capacitance, and other issues.
