Table 12-24 Maximum motor cable lengths (400 V drives)
Table 12-25 Maximum motor cable lengths (575 V drives)
Table 12-26 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 Table 12-23
and Table 12-24 if high capacitance motor cables are used. For further
information, refer to section 4.9.2 High-capacitance / reduced diameter
cables on page 64.
