 Caution
High frequency wave noise from other devices in the installation environment
may cause errors in communications. When designing a system, use protective
measures to avoid the influence of high frequency wave noise as follows:
1. Wiring
Wire Ethernet cables so that they are well-separated from other cable
systems such as the main circuit or power lines.
2. Communication system (Ethernet)
• Communicate data to a remote device.
• Yaskawa strongly recommends shielded Ethernet cables.
3. Attach a ferrite core.
This will help reduce the occurrence of electrical interference.
Recommended ferrite core:
