i.4 Notes on Using Drives
Radio Frequency Interference
n
Inputs and outputs of the drive (main circuit) contain harmonic components that may adversely affect communication
devices, such as AM radios, used in the vicinity. Use high-voltage cables and ground any shielded cables. Separate cables
for control from high-current circuits (main circuit and relay sequence circuits) to avoid induction from peripheral
devices. (It is advisable to separate them by a distance of 30 cm or more.)
Leakage Current
n
Harmonic leakage current passes through stray capacitance between the drive power lines, ground and the motor lines.
Consider taking measures against this leakage current.
