Product Details

  • Melservo MR-J2 Servo Amplifier (MRJ2100B)
  • Manufacturer: Mitsubishi
  • Series: MELSERVO MR-J2

Product Description

The Mitsubishi MR-J2-100B (MRJ2100B) is a 1kW, 200V Melservo MR-J2 servo amplifier. There are 3-phases in this servo amplifiers voltage; the voltage may span from 200 to 230VAC and the frequency is 50/60Hz. The voltage can fluctuate while the 3-phases remains stable with the voltage is permitted to span between 170 to 253VAC. The frequency is allowed to fluctuate between +5% and -5% of 50/60Hz. The frequency response of the MR-J2-100B servo amplifier speed is 250Hz.

The MR-J2-100B servo amplifier may attach to one of three servo motors, such as: HC-SF81, HC-SF102, and HC-SF103. Connections of the motor to the servo amplifier made will be delineated below.

The MR-J2-100B servo amplifier can attach to a servo motor by two ways. Firstly, it may link by an encoder cable to the servo motor’s encoder and the CN2 port. Secondly, the servo motor may also connect to three of the amplifier’s screw terminals, U, V, and W, by utilizing a servo motor power cable. The other three screw terminals, L1, L2, and L3, may connect to a reactor (the FR-BAL) which can connect to a magnetic contactor which then may connect to no-fuse or fuse breaker. The MR-J2-100B amplifier has a CN3 which can connect to a personal computer. Then, the CN1A and CN1B ports both connect to other MR-J2-B servo amplifiers. The CN1A port can only connect the CN1B port of a preceding MR-J2-B servo amplifier, while the CN1B port may connect to the CN1A port of a succeeding MR-J2-B amplifier.
