Figure 8.23 Preventing Induced Noise
Reducing Radiated and Radio Frequency Noise
The drive, input lines, and output lines generate radio frequency noise. Use noise filters on input and output sides and install
the drive in a metal enclosure panel to reduce radio frequency noise.
Note:
The cable running between the drive and motor should be as short as possible.

Installing Input Fuses
NOTICE:
If a fuse is blown or a Ground Fault Circuit Interrupter (GFCI) is tripped, check the wiring and the selection of the peripheral devices.
Check the wiring and the selection of peripheral devices to identify the cause. Contact Yaskawa before restarting the drive or the peripheral
devices if the cause cannot be identified
