Product Details

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

Product Description

The Mitsubishi MR-J2S-40B (MRJ2S40B) is a servo amplifier from the 200V class springing out of the Melservo MR-J2 series. The MR-J2S-40B 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 can be matched appropriately with motors from theHC-MFS, the HC-RFS, and the HC-SFS, and most 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 (A171SH, A172SH, A173UH, Q172, Q173) or positioning controllers (A1SD75M, QD75M) that is compatible with SSCNET; the SSCNET can be affixed to a CN1B connector. A CN2 connector canned 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°C (32 to 131°F). Safety features resuscitation overvoltage closure, overcurrent cessation and encompass surcharge closure (electronic thermal). Other features relating to well-being of the servo motor are overheat support, overspeed safeguarding, encoder culpability protection, excessive blunder protection, undervoltage and unforeseen power outage defense, and regeneration fault preservation.
