Product Details

  • Melservo MR-J2 Servo Amplifier 400W (MRJ2S40A)
  • Manufacturer: Mitsubishi
  • Series: MELSERVO MR-J2

Product Description

The Mitsubishi MR-J2S-40A (MRJ2S40A) is a 400W Melservo MR-J2 series servo amplifier that has an output waltage of 400W. This servo amplifier has an output of 170 volts and with a frequency of 0-360Hz. The servo amplifier also possesses a 1 phase input voltage of 230 with a frequency 50/60Hz or a 3 phase input voltage of 200 to 230 with a frequency of 50/60Hz. The servo amplifier external analog input or the parameters is circumscribed by the MR-J2S-40A limit of its torque which is 0 to +10VDC that is its maximum torque. The servo amplifier also uses a RS-232C/RS-422 cable for personal computer interface. Its input impedance expands between 10 to 12 kilo-ohms. The MR-J2S-40A’s command speed for the analog input of the amplifier is 0 to ±8VDC. This MR-J2 servo amplifier has 3 phases for its analog and digital inputs that is formed of two analog reference inputs and a digital pulse train input which supports three different pulse trains with pulse command reverberating 0 to ±10000 times.

The MR-J2S-40A servo amplifier can have a PC connected to the CN3 port and a CN1B port with a junctional terminal block and a battery department for a permissive A6BAT battery. The MR-J2S-40A is normally adjoined with a motor and encoder to a CN2 interface. Motors that it can be conjoined to are these, the: HC-KFS43 and HC-MFS43. There are two ways to unite the chosen servo motor to the servo amplifier, and that is shown in the top brochure link.

The surroundings of the MR-J2S-40A should keep a clime temperature ranging in the degrees of 0 and 55°C (32 to 131°F).
