Product Details

  • Melservo MR-J4 Servo Amplifier with SSC NETWORK (MRJ4200B)
  • Manufacturer: Mitsubishi
  • Series: MELSERVO MR-J4

Product Description

The Mitsubishi MR-J4-200B (MRJ4200B) is a Melservo MR-J4 servo amplifier with an SSC Network connections. The servo amplifier has a 3-phase output voltage of 170VAC and its current is 11.0 Amp. The MR-J4-200B servo amplifier has a main circuit power supply with a voltage ranging from 200 to 240VAC, a frequency of 50/60Hz, and a rated current of 10.5 Amp. The servo amplifier permits a voltage fluctuation within the range of 170 to 264VAC and flexible frequency of ±5%.

Many rotary and linear motors may be annexed to the MR-J4-200B servo amplifier by a connection with a motor power cable and the encoder cable. The rotary motors that this amplifier connects to are four motors from the HG-SR, 4 from the HG-JR, two from the HG-RR, and one from the HG-UR series. Then there are six motors that may connect to the MR-J4-200B from the LM linear motors.

The IP enclosure rating for the MR-J4-200B is IP20. This rating indicated that the means that the servo amplifier is sheltered from contiguity from contact made by small foreign objects and incidental contact from fingers.

Connections with peripheral equipment may be made to the MR-J4-200B servo amplifier with an SSC Network by its many ports along the top. Besides the peripheral connection made by the motor is the USB (MR-J3USBCBL3M) communication connector made when it is coupled to the CN5 port. Peripheral connections to the MR-J4-200B are made to other servo amplifiers by Servo System Control Network (SSCNET, SSC Network) III-H connectors to either or the CN1A and the CN1B.
