3.2.2.3 Recommended Control and Signal Wire Sizes
The recommended wire sizes to connect I/O signals to the terminal strip on the Regulator board are
shown in table 3.8. Recommend terminal tightening torque is 0.5 Newton meters (4.5 in lbs).
3.2.2.4 Recommended Motor Lead Lengths
The following motor lead lengths are recommended to reduce line disturbances and noise. See
figure 3.3.
For applications using one motor, motor lead length should not exceed 76 meters (250 feet).
For applications with multiple motors, total motor lead length should not exceed 76 meters
(250 feet).
When total lead length exceeds 76 meters (250 feet), nuisance trips can occur. These trips are
caused by capacitive current flow to ground. Note that these capacitively coupled currents should be
taken into consideration when working in areas where drives are running. If the motor lead length
must exceed these limits, output line reactors or other steps must be taken to correct the problem.
Note that drives set up for vector regulation can only be connected to one motor at a time.
