Table 12-27 Maximum motor cable lengths (575 V drives)
Table 12-28 Maximum motor cable lengths (690 V drives)
• 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 section 4.8.1 Cable types and lengths on page 86 if high capacitance or reduced diameter
motor cables are used. For further information, refer to section 4.8.2 High-capacitance / reduced diameter cables on page 87.
