Product Details

  • Melservo MR-J2 Servo Amplifier (MRJ2S40B)
  • Manufacturer: Mitsubishi
  • Series: MELSERVO MR-J2

Product Description

The Mitsubishi MR-J2S-40B (MRJ2S40B) is a 200V servo amplifier from the Melservo MR-J2 series. This servo amplifier provides 400W, it has a 3 phase input with voltage of 200 to 230VAC and a frequency 50/60Hz or a 1 phase input with a voltage of 230VAC and a frequency 50/60Hz. The amplifier outputs with a frequency from 0-360Hz a voltage of 170V. By participating in the MR-J2S-B servo amplifier series, the MR-J2S-40B can facilitate attaching to controller module through Servo System Control Network (SSCNET) that moreover allows amplifiers to modulate motor break. The servo amplifier utilizes a RS-232C/RS-422 cable for PC interface as well.

The MR-J2S-40B servo amplifier might be able to match appropriately with certain motors from either the HC-MFS, the HC-RFS, the HC-SFS, or possibly other motors from a HC-[]FS motor series. The MR-J2S-40B has a compartment for an optional MR-BAT Battery.

The MR-J2S-40B can be hitched to a CN1A connector to a motion controller (Q172, Q173, etc.) or positioning controllers (A1SD75M or QD75M) that is compatible with SSCNET; the SSCNET can be affixed to a CN1B connector. The same connector can also be utilized in the connection with other servo amplifiers of like kind A CN2 connector can be used to connect the MR-J2S-40B servo amplifier to a servo motor.

To sustain its usual operations, the surroundings of the MR-J2S-40B should maintain an ambient temperature within 0 and 55 degrees Celsius (32 to 131 degrees Fahrenheit).
