Table 4-8 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 maximum cable length is reduced from that shown in Table 4-7 to Table 4-10 if high capacitance or reduced diameter motor cables are used.
