YASKAWA TOEPYAIL1E01A YASKAWA AC Drive L1000E 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.
