5.1.21 Maximum motor cable lengths
Since capacitance in the motor cable causes loading on the output of the drive, ensure the cable
length does not exceed the values given in Table 5-23.
Use 105 °C (221 °F) (UL 60/75 °C temp rise) PVC-insulated cable with copper conductors having a
suitable voltage rating, for the following power connections:
• AC supply to external EMC filter (when used)
• AC supply (or external EMC filter) to drive
• Drive to motor
• Drive to braking resistor
Table 5-23 Maximum motor cable lengths
* For the Unidrive M200 to M400, the cables lengths at 0.667 and 1kHz switching frequency are the
same as cable lengths at 2 kHz.
• Cable lengths in excess of the specified values may be used only when special techniques are
adopted; refer to the supplier of the drive.
• The default switching frequency is 3 kHz for Open-loop and RFC-A and 6 kHz for RFC-S mode.
The maximum cable length is reduced from that shown in Table 5-23 if high capacitance or reduced
diameter motor cables are used, refer to section 4.8.2 High-capacitance / reduced diameter
cables on page 68.
