Product Details

  • Melservo MR-J4 Servo Amplifier with an SSC NETWORK (MRJ4100B)
  • Manufacturer: Mitsubishi
  • Series: MELSERVO MR-J4

Product Description

The Mitsubishi MR-J4-100B (MRJ4100B) is a Melservo MR-J4 servo amplifier with an SSC Network system. This servo amplifier is able to generate 1kW and a rated current of 5.0A. The main circuit power supply of the amplifier has a 3-phase voltage of 200 to 240VAC with a maximum range of 170VAC to 264VAC and a frequency is 50/60Hz that has a maximum fluctuation of ±5%.

The MR-J4-100B servo amplifier can be paired with five different motors, one which is a direct drive motor; the other four are rotary motors (this servo amplifier cannot be applied to any linear amplifier). The direct drive motor that corresponds with this amplifier is the TM-RFM018E20. The HG-KR, HG-MR, HG-SR, HG-JR series are the other four rotary motor series that may be connected with the MR-J4-100B servo amplifier.

The MR-J4-100B servo amplifier with an SSC NETWORK may use any of those motors mentioned above. By connecting the amplifier to the motor cable attached to the terminal block and the encoder cable to the CN2 Port. Above the CN2 port is a CN1A/CN1B port in which is used a Servo System Control Network (SSCNET) III/H connector to a servo system controller or to another servo amplifier. Above those ports is the CN8 port which connects to the MR-J3-D05 safety logic unit or an external safety relay. Once again, above that is the CN3 port which connects with an I/O signal connector. Finally, a USB communication connector may be attached to a CN5 connector in order for the MR-J4-100B servo amplifier to be hooked up with a personal computer.
