Frequently Asked Questions (FAQ)

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

SSCNET III is the standard high-speed network. SSCNET III/H is an enhanced version with even higher transmission speeds. The MR-J3-500BS-EB uses SSCNET III, which is fully compatible with controllers supporting this protocol.

What does "conformal coating" do?

It is a thin protective polymer film applied to the circuit board. It shields electronic components from corrosion caused by humidity, dust, and mild chemical exposure, increasing reliability in non-hermetic industrial environments.

Is a braking resistor included?

No. A drive of this power (5 kW) typically requires an external regenerative braking resistor to be purchased separately and connected to the designated terminals to dissipate energy during motor deceleration.

Can I use this drive in a single-phase power system?

No. The MR-J3-500BS-EB is specifically designed for three-phase 200V AC input. Using single-phase power will not work and could damage the unit.

What does Safety Category B mean?

It is a defined level of safety for control systems. Category B signifies the drive incorporates basic safety principles and fault detection. For full machine safety, it must be integrated into a wider safety circuit designed by the machine builder.
