To prevent the mutual coupling generating disturbance, the control cables, power cables and motor cables
must be laid apart as far as possible, especially when the cables are run in parallel to a long distance. If the
control cables must cross the power ones, run them at right angles.
Signal/control cables
The longer the motor cables or the larger the section area of motor cables, the larger the ground
capacitance, and the stronger the mutual coupling and disturbance. Therefore, the cables with specified section
area and minimum length should be used.
