Table 12-19 Maximum motor cable lengths (200 V drives)
Table 12-20 Maximum motor cable lengths (400 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.
The maximum cable length is reduced from that shown in Table 12-18,
Table 12-19 and Table 12-20 if high capacitance motor cables are used.
For further information, refer to section on page 39.
