Product Details

  • Melservo MR-J2 Servo Amplifier 3.5kW (MRJ2S350A)
  • Manufacturer: Mitsubishi
  • Series: MELSERVO MR-J2

Product Description

The Mitsubishi MR-J2S-350A (MRJ2S350A) is a Melservo MR-J2 series servo amplifier with a 3.5kW output wattage. This servo amplifier has a pulse command of 0 to ±10000 pulses and a personal computer interface cable. Process impedance that spans from 10 to 12 kilo-ohms and a command speed of 0 to ±8VDC (maximum torque). The MR-J2S-350A is a 3 phase digital/analog input. The digital pulse train input and a two analog reference input within the amplifier aid three distinct pulse trains: pulse train for right and left rotation; pulse and direction; encoder signals. The MR-J2S-350A inputs 200-230 Volts with the frequency 50-60Hz and outputs 170 Volts with the frequency of 0-360Hz. The MR-J2S-350A, being managed by parameters or its external analog input, has a torque limit bounds from 0 to +10VDC (maximum torque).

The MR-J2S-350A 200V servo amplifier is normally suitable for a servo motor and encoder with a CN2 connector. Many servo motors can be connected with this amplifier, the HC-SFS352 and HC-RFS203. There are a couple of means to attach one of these servo motors to this amplifier, and this can be seen in one of the images shown in one of the brochures below. There is also a battery compartment for an optional A6BAT Battery. A junctional terminal block can be attached with a CN1B connector and a PC can also be joined with a CN3 connector.

The ambient temperature must be between 0 and 55°C (32 to 131°F) for the surroundings of the MR-J2S-200A servo amplifier to sustain its normative operations.
