• Select the I/O signal wires for external wiring to connect the product
to external devices based on the following criteria:
• Mechanical strength
• Noise interference
• Wiring distance
• Signal voltage
• Separate the I/O signal cables for control circuits from the power
cables both inside and outside the control panel to reduce the influ-
ence of noise from the power cables.
If the I/O signal lines and power lines are not separated properly, mal-
function may occur.
• Whenever possible, use the Cables specified by Yaskawa.
If you use any other cables, confirm the rated current and application
environment of your model and use the wiring materials specified by
Yaskawa or equivalent materials.
