Installation & Compatibility Guide

This cable connects the CN2 encoder port on your MR-J3 series servo amplifier to the encoder connector on your compatible Mitsubishi servo motor. Ensure the motor and amplifier power are OFF before connection. Match the connector keying to the ports and secure the locking rings firmly. Route the cable away from power lines and noise sources. Use cable clamps to support the cable and avoid sharp bends, especially near the connectors. The IP65 rating allows it to be used in areas exposed to washdown, but connectors must be properly mated and locked to maintain the seal.

Frequently Asked Questions (FAQ)

Can I use this cable with an MR-J4 or newer amplifier?

No. The MR-J3ENCBL10M-A1-L is specifically designed for the MR-J3 series amplifier connector interface. MR-J4 and other series use different connectors and pinouts. Always use the cable specified for your amplifier generation.

What does the "-L" suffix in the part number mean?

In Mitsubishi's naming, the "-L" often indicates a cable with a specific locking mechanism or connector type. It is part of the exact part number required to ensure compatibility with the listed motor series.

Is it safe to coil up excess cable length?

It is not recommended to coil excess cable tightly, as this can create electromagnetic interference (noise) that may affect signal integrity. If you have excess length, lay it in a loose figure-eight pattern.

What happens if I use a longer or shorter cable?

Using a cable longer than the maximum recommended by Mitsubishi (which varies by model) can cause signal degradation and encoder errors. Using a shorter cable is generally fine, but this 10m length is a standard offering for flexible installation.

Can I repair this cable if the connector is damaged?

These are factory-molded cables. Repairing the molded connector is very difficult and will compromise the IP65 rating and signal integrity. If damaged, replacement of the entire cable is the recommended course of action.
