Product Details

  • Melservo MR-J2 200W Servo Amplifier (MRJ2S20A)
  • Manufacturer: Mitsubishi
  • Series: MELSERVO MR-J2

Product Description

The Mitsubishi MR-J2S-20A (MRJ2S20A) is a Melservo MR-J2 series servo amplifier that generates an output wattage of 200W. This servo amplifier possesses a 3 phase input voltage that ranges from 200 to 230 and whose frequency is 50/60Hz or otherwise it may have a 1 phase input voltage that is at 230 whose frequency is also 50/60Hz. The MR-J2S-20A has an output of 170 volts and with a frequency of 0-360Hz. This 200W servo amplifier also has a RS-232C/RS-422 cable for PC interface. The specifications or the external analog input of the servo amplifier is restrained by the MR-J2S-20A’s the maximum torque curb is 0 to +10VDC. The MR-J2S-20A amplifier has an analog and digital input in 3 phases that is shaped by a digital pulse train input and two analog reference inputs which supports three contrastive pulse trains. The Melservo MR-J2 servo amplifier has 0 to ±10000 pulses as its pulse command. The analog input’s command speed of the MR-J2S-20A is 0 to ±8VDC for the maximum torque. The input impedance of the amplifier stretches from 10 to 12 kilo-ohms.

The MR-J2S-20A is commonly equipped to a servo motor and encoder to its CN2 connector. The amplifier may be partnered with motors. These are those applicable motors, the: HC-KFS23 and the MFS23. These motor can be attached by two means, both of which can be read in the brochure. A PC may also be linked with a CN3 interface and a CN1B interface with a terminal block that connect to motors or other peripheral equipment with the use of adapters. There is a battery compartment, also, for a A6BAT battery that is optional.

0 and 55°C (32 to 131°F) ambient temperatures must be upheld in the confines of the MR-J2S-20A.
