Frequently Asked Questions

Can I use this cable to connect two amplifiers together?

• No, this cable is for connecting a controller (Q17 HCPU) to an amplifier. For amplifier-to-amplifier connections, you need a different cable type specified in the system manual.

Why choose fiber optic over a standard wire cable?

• Fiber cables like the MR-J3BUS5M are immune to electrical noise. This is crucial in factories with many motors and drives. It ensures your servo commands are never corrupted, leading to more stable machine operation.

What happens if I bend the cable too sharply?

• A sharp bend can break the thin glass fibers inside. This will cause complete signal loss. Always maintain a bend radius larger than 25mm. If the cable feels stiff, do not force it.

Is this cable compatible with the newer MR-J5 series?

• Yes, the MR-J3BUS5M is listed as compatible with the MR-J5-B series. The SSCNET III protocol is common across these generations, making this cable a versatile choice for system upgrades.

How do I clean the optical connectors?

• Dust on the connectors is a common cause of failure. Use a dedicated optical connector cleaner or lint-free swabs with isopropyl alcohol. Never touch the connector end face with your fingers. Inspect it with a magnifier for scratches.
