Motor Cable Length

Below are cable length guidelines for use with most standard industrial motors.
Suggested Maximum Output Cable Distances
AC Motor Voltage
2300
2300/4000
4000V or 2300/4000
6600V
CAUTION
(1) Older motors, or motors with marginal insulation systems, may require filters to help reduce the stress on
the insulation system. Consult Toshiba application engineering.
(2) Exceeding the peak voltage and allowable voltage rise time of the motor insulation system will reduce
motor life expectancy. To insure good insulation life, consult with the motor supplier to determine motor
insulation ratings and allowable maximum output lead distance. Long lead lengths between the motor and
drive may require that filters be added to the drive output.
