Professional FAQ

• What is the primary application for this high-power amplifier?

The MR-J3-500A is designed to drive large servo motors in heavy-duty applications such as large machine tools, press feeds, material handling systems, and industrial robots requiring 5kW of power.

• Why does this model include a built-in regenerative resistor?

The integrated resistor safely dissipates excess energy generated by the motor during deceleration or overhauling loads, preventing drive faults and protecting the system without needing an external unit.

• Can this amplifier accept standard pulse train commands?

Yes, it supports high-speed pulse input, compatible with differential receivers up to 1Mpps and open-collector inputs up to 200kpps for flexible connectivity with various controllers.

• What does the "force-cooling" design mean for installation?

It requires an external cooling fan to maintain optimal operating temperature. Ensure adequate clearance around the unit for airflow and follow the specified ventilation guidelines in the manual.

• Is the 24VDC interface supply used for the motor power?

No, the 24VDC is solely for the amplifier's control circuits, I/O signals, and communication interface. The motor receives its power from the main 3-phase AC supply.
