Frequently Asked Questions

What is the difference between SSCNET III and SSCNET III/H?

• SSCNET III is the standard protocol. SSCNET III/H offers enhanced functions, like improved synchronization for multi-axis systems. The MR-J3-11KBS4 motor is compatible with both, but your master controller (PLC) will determine which one is used.

Can I use this motor with an amplifier from another brand?

• No. The MR-J3-11KBS4 is designed for Mitsubishi's ecosystem. The encoder feedback, communication protocol, and safety wiring are proprietary. It must be paired with a compatible Mitsubishi MR-J3 series servo amplifier.

How do I use the pulse train input feature?

• The pulse train input allows you to control the motor with a standard pulse/direction signal from a simple motion controller or PLC without SSCNET. This offers a fallback or alternative control method for simpler setups.

Is the cooling fan on the motor always running?

• Typically, yes. The fan runs when the amplifier is powered on to ensure proper cooling. Some high-efficiency models may have fan control, but standard operation assumes continuous fan operation for thermal management.

What does the Safe Torque Off (STO) function actually do?

• STO is a safety function that safely disables the motor's ability to produce torque. When the STO circuit is opened (e.g., by an emergency stop), power is cut from the motor's power transistors. This allows for safe maintenance but does not mechanically brake the motor shaft.
