8 Motor cable lengths
Table 8-1 Motor cable lengths
The capacitive loading of the drive by the motor cable means that the cable length limits shown in table 8-1 must be observed. Failure to do so can
result in spurious OI.AC tripping of the drive. If longer cable lengths are required, consult LEROY-SOMER.
The maximum cable lengths were measured using cable with capacitance of 130pF/m.
This capacitance was measured by taking one phase as one node and the screen (shield) and earth (ground) (if any) as the other node, then
measuring the capacitance between the two points.
