  • Manufacturer: Mitsubishi
  • Series: MELSERVO MR-J3

Product Description

The Mitsubishi MR-J3-200B (MRJ3200B) is a 2kW, 200V Melservo MR-J3 servo amplifier. The customary voltage of the power supply of this servo amplifier spans from 200 to 230VAC which runs on 3-phase. The frequency of this servo amplifier is 50/60Hz. The voltage is authorized to span between 170 to 253VAC with the same 3-phase. The frequency is permitted to waver between +5% or -5%. The frequency response has a speed of 900Hz.

The MR-J3-200B servo amplifier may attach to a HF-SP or HC-RP servo motor series: HF-SP152, HF-SP202, HC-RP103, and HC-RP153. These servo motors may be linked to the servo amplifier by the port described below.

The MR-J3-200B servo amplifier has many ports, in particularly, the CN1A and CN1B ports. These two ports, while linked to the SSCNET III, can connect with other MR-J3-B servo amplifier. The CN1B port can connect the CN1A port of a succeeding servo amplifier and vice versa. The CN1A port may also concatenate to a motion control module from the MELSEC Q series. The MR-J3-200B servo amplifier may also connect to one of the aforementioned servo motors by attaching the motor to the CN2 port. The CN5 port may attach to a personal computer that deploys a MR Configurator. This personal computer may also link to module participating in the Mitsubishi MELSEC Q series configuration. The MR-J3-200B servo amplifier also has thee connectors. These connectors are for attaching to the power supplies of these places in or outside the module: main circuit (CNP1 connector), control circuit (CNP2 connector), and motor (CNP3 connector).
