Product Details

  • Melservo MR-J2 Servo Amplifier (MRJ2S100B4)
  • Manufacturer: Mitsubishi
  • Series: MELSERVO MR-J2

Product Description

The Mitsubishi MR-J2S-100B4 (MRJ2S100B4) is a 400V servo amplifier from the MELSERVO MR-J2 series. The 3 phase frequency and voltage of this amplifier starts at 50/60Hz and a voltage spanning from 380 to 480VAC. Yet, also in this main circuit power supply, the admissible voltage fluctuation is 323 to 528VAC with a wavering frequency given an extra ±5%. Nonetheless, for the control circuit power supply of the MR-J2S-100B4, the voltage is at 24VDC with an allowable fluctuation between 20.4 and 27.6VDC with a wattage capacity of 25W.

The MR-J2S-100B4 servo amplifier is suited for the HC-SFS1024 servo motor which is a medium inertia motor. These low motor is a stable control which executes operations from low to high speeds. This motor may connect by using an encoder cable.

The MR-J2S-100B4 servo amplifier has four interfaces which can attach with four connectors. The encoder cable that is linked with the motor can append to the amplifier using a CN2 connector. The CN3 connector once attached to the port may connect the amplifier to a personal computer. The CN1B connector permits for connection and communication between other amplifiers. This port creates a network of amplifiers controlling other motors. Lastly, the CN1A connector links the MR-J2S-100B4 servo amplifier to a SSCNET system. This connection allows the amplifier to connect with many different Mitsubishi modules such as motion controllers (there are five modules in which the amplifier may connect with that span from 4 to 32 axis control) and positioning controllers (A1SD75M or QD75M).
