Frequently Asked Questions

What is the advantage of having both EtherCAT and SSCNET III/H?

• It offers ultimate flexibility. You can integrate the MR-J3-700A4-ETHERCAT into a standard EtherCAT network with a non-Mitsubishi PLC or use it in a pure, high-speed Mitsubishi SSCNET system. This future-proofs your investment.

How do I choose between using EtherCAT or SSCNET III/H?

• The choice depends on your system's main controller. Use EtherCAT if your master PLC supports it (e.g., many brands). Use SSCNET III/H if you have a Mitsubishi Q/L series PLC that uses that network. You select the mode via amplifier parameters.

What size of external regenerative resistor is needed?

• The required resistor wattage and ohmic value depend on your motor inertia and cycle time. Refer to the amplifier's installation manual or use Mitsubishi's sizing software to select the correct component to avoid faults.

Is the cooling fan loud?

• Like most forced-air cooling systems, the fan generates noticeable noise. For noise-sensitive environments, ensure the control cabinet is located appropriately or consider acoustic damping, while strictly maintaining required airflow.

Can I control this drive directly from a PC?

• Yes, but you need additional hardware. For EtherCAT, you would need a PC with an EtherCAT master card and software. For SSCNET III/H, direct PC control is complex; it's typically done through a Mitsubishi motion controller or PLC.
