Product Details

  • Melservo MR-J3 Servo Amplifier 1kW (MRJ3100B)
  • Manufacturer: Mitsubishi
  • Series: MELSERVO MR-J3

Product Description

The Mitsubishi MR-J3-100B (MRJ3100B) is a Melservo MR-J3 series servo amplifier with an output wattage of 1kW. This servo amplifier has a power supply with 3-phase voltage that spans between 200 to 230VAC and a frequency of 50/60Hz. This voltage range may swell to the same 3-phase voltage of 170 to 253VAC and the frequency can orbit between +5% and -5%. The frequency response of the servo amplifier’s speed is 900Hz. Since the MR-J3-100B servo amplifier uses the SSCNET III, which has a communication speed is 50 Mbps.

The MR-J3-100B servo amplifier can attach itself to only one motor, the HF-SP102 servo motor. This motor is of the medium inertia type.

The MR-J3-100B servo amplifier can connect to a motion control module which resides in the MELSEC Q series system with its CN1A port. Then, the CN1B port may attach to the CN1A port of a neighboring MR-J3-B servo amplifier with the use of the SSCNET III. Next the CN2 connector can link to the aforementioned applicable servo motor, the HF-SP102. The MR-J3-100B servo motor also has a CN3 port may link to an I/O signal. The last port, the CN5 port, may attach to a personal computer that utilizes the MR Configurator (this computer may also connect to the MELSEC system). There are also three connectors. All three of the connectors of the MR-J3-100B servo amplifier are used for the power supply. The CNP1 connector is for the main circuit, the CNP2 connector is utilized for the control circuit, and CNP3 connector is employed as a power supply for the motor.
