FAQ – Expert Installation Advice

What is the main benefit of force-cooling in this model?

Force-cooling (a fan) allows the MR-J3-100T to maintain its full 1kW power rating in warmer environments or tight panels where natural cooling isn't sufficient, ensuring consistent performance.

Can I use this amplifier with both CC-Link and RS-422 networks?

Yes, the MR-J3-100T supports both protocols. You choose which one to use based on your factory network. This dual compatibility makes it very flexible for system upgrades or integration.

Is an external regenerative resistor required?

The unit has a built-in resistor for typical braking energy. For applications with very frequent stopping or high inertia loads, you should calculate the regeneration energy to see if an external resistor is needed.

How should I mount it for best cooling?

Mount vertically on a flat, solid panel. Ensure the intake and exhaust vents (top/bottom or sides as per manual) have at least 100mm of clear space for proper airflow and to prevent overheating.

The manual mentions "IP00". What precautions does this require?

IP00 means no protection against dust or water. You must install the MR-J3-100T inside a protective control cabinet to shield it from dust, metal chips, oil mist, and any liquids.
