Product Details

  • Melservo MR-J3 Servo Amplifier 200W 200V (MRJ320A)
  • Manufacturer: Mitsubishi
  • Series: MELSERVO MR-J3

Product Description

The Mitsubishi MR-J3-20A (MRJ320A) is a 200W, 200V Melservo MR-J3 servo amplifier. The power supply runs on either a 3-phase or 1-phase. The 3-phase of the servo amplifier has a voltage orbit of 200 to 230VAC while the 1-phase voltage of 230VAC. Both types of phases have frequencies of 50/60Hz. The MR-J3-20A servo amplifier can, however, may be permitted to have its voltage span from 170 to 253VAC for the voltage that operates on 3-phases, while the voltage which runs on 1-phase is authorized to span between 207 to 253VAC. The MR-J3-20A servo amplifier also has a frequency response whose speed is 900Hz.

The MR-J3-20A servo amplifier may link to two servo motor models: HF-KP23 and HF-MP23. Two connections may be made between the servo amplifier and motor. These connections will be narrated below.

The MR-J3-20A servo amplifier has a great number of ports. The CN5 port may connect to a personal computer that utilizes a MR Configurator by the MR-J3USBCBL3M cable. The CN3 port connects by using a RS-232 communication to an operator panel of the GOT series. The CN1 port connects to a terminal block which can then link to positioning control module which is from the FX series or Q series. Then, the CN6 port can be used as an output for analog monitor for the servo amplifier. The MR-J3-20A servo amplifier also connects to the selected servo motor’s encoder by the CN2 port. The servo motor cable of the servo motor also links to the U, V, and W connector.
