YASKAWA ELECTRIC TOEP C710616 38F YASKAWA AC Drive L1000A Quick Start Guide

Take the following steps to prevent erroneous operation caused by noise interference:

• Use shielded wire for the PG encoder signal lines.
• Limit the length of all motor output power cables to less than 100 m. Limit the length of open-collector output lines to

less than 50 m.

• Use separate conduit or cable tray dividers to separate option control wiring, main circuit input power wiring, and

motor output power cables.
