Professional FAQs

What is the main advantage of SSCNET III/H for a small 100W drive?

Even for small axes, the network provides benefits like simplified wiring (one fiber cable vs. many wires), centralized control from one CPU, and perfect synchronization with other axes in the system, which is crucial for coordinated motion.

Does this drive require an external brake resistor?

For most 100W applications with minimal inertia, the internal circuits can typically handle the regenerative energy. For applications with frequent fast stops or vertical axes, consult the manual to see if an external resistor is recommended.

Can I control this drive with pulse train signals from a standard PLC?

No. The "T" in MR-J3-10T typically indicates it is a network-type drive with SSCNET. For pulse train control, you would need a "B" series model (e.g., MR-J3-10B).

Is a 24VDC power supply required for the control circuits?

Yes. Like most servo drives, it requires a separate 24VDC power supply to energize its control logic and the SSCNET III/H communication interface before applying main AC power.

What is the protection rating (IP) of this amplifier?

Amplifiers in the MR-J3 series are typically IP00 (open chassis). They must be installed inside a protected control cabinet that provides the necessary environmental sealing.
