Professional FAQ

• What is the primary function of this feedback cable in a servo system?

This cable transmits critical encoder signals (position, speed) from the servo motor back to the amplifier. Accurate feedback is essential for the drive to perform precise closed-loop control. Any signal degradation or loss in this cable can cause positioning errors or drive faults.

• Why is the IP67 rating important for a feedback cable?

The IP67 rating means the connectors are completely sealed against dust and can withstand temporary immersion in water. This allows the MR-J3ENCBL30M-A2-H to be used in washdown environments, outdoor applications, or areas with high humidity and particulate contamination.

• Can I use this 30m cable for any length under 30 meters?

While physically possible, it is not recommended. Excess cable should not be tightly coiled, as this can cause electrical noise interference (acting as an antenna) and signal integrity issues. It is best practice to select a cable length that closely matches your required run.

• What does "extra flexible / long-lasting bend durability" mean for machine design?

This specification indicates the cable is suitable for use in cable carriers (e.g., energy chains) on moving machine parts. It is designed to withstand millions of flexing cycles without conductor breakage or shield degradation, which is crucial for robots or gantry systems.

• Are the connectors pre-attached, and are they keyed for correct orientation?

Yes, the cable comes with both motor-side and amplifier-side connectors pre-attached. Mitsubishi connectors are typically keyed, meaning they can only be plugged in the correct way, preventing installation errors and potential damage to the encoder or amplifier ports.
