FAQ – Professional Installation Guidance

What is the advantage of SSCNET III/H communication?

It provides ultra-fast, noise-resistant data transfer via fiber optics. This allows synchronized multi-axis control and longer cable runs without signal loss, perfect for complex machinery.

How does the 18-bit absolute encoder benefit my system?

It eliminates the need for a homing routine on power-up because it always knows the exact position. This saves cycle time and allows for immediate operation after a power loss.

Is the built-in regenerative resistor enough for a 2kW drive?

It handles standard braking energy. For high-duty cycles, rapid cycling, or very high inertia loads, you must calculate the regeneration power and likely add an external resistor bank.

Can I use this amplifier with a single-phase power source?

No. The MR-J3-200B requires a three-phase 200-230V AC power input for its main circuit. Ensure your facility has this power available.

The auto-tuning didn't fully eliminate vibration. What should I do?

First, ensure all mechanical parts (couplings, guides) are tight. Then, use the drive's manual tuning parameters to fine-tune the gain settings. Often, slightly reducing the speed gain can stabilize the system.
