• Use shielded motor and control circuit lines and lay control circuit lines at least 30 cm away from power lines in order
to prevent malfunction due to induced noise.

Figure 8.13 Reducing Radio Frequency Noise
n Input-Side Noise Filter
Drive outputs generate noise as a result of high-speed switching. This noise flows from inside the drive back to the power
supply, possibly affecting other equipment. Installing a noise filter to the input side of the drive can reduce the amount of
noise flowing back into the power supply. This also prevents noise from entering the drive from the power supply.
• Use a noise filter specifically designed for AC drives.
• Install the noise filter as close as possible to the drive.
