Product Details

  • R88D Servo Drive 400W (R88DWT04H)
  • Manufacturer: Omron
  • Series: R88D

Product Description

The Omron R88D-WT04H (R88DWT04H) is a 400W servo drive from the R88D series. The servo drive has an output current of 2.8 Amps and may be able to temporarily attain a current that outputs 8.5 Amp. The power supply of the main circuit and the control circuit are both 1-phase, with voltages that operate between 200 and 230VAC, even to the point of reaching the nadir and pinnacle of 170 and 253VAC. The R88D-WT04H servo drive may also heat to 20W in its main circuit and 13W in its control circuit. The pulse width modulation of the servo drive has a frequency of 11.7kHz.

The servo motors which may be applied to the R88D-WT04H output servo drive are these: R88M-WP40030H, R88M-WP40030T, R88M-W40030H and R88M-W40030T. All these drives mentioned have rotations of 3000rpm but the last two are of the standards and the first are flat motors. The R88D-WT04H servo drive, in order to connect to one of these motors, must link its CN2 port with an encoder cable that attaches to the chosen motors encoder. The terminal block on this drive may link with a power cable that can then attach to another connecting point on one the motors.

Some other connections possible for the R88D-WT04H output servo drive is with a parameter module using the CN3 port. The CN1 port may link with a variety of other applications such as a motion or position control module. The CN8 port can attach itself to the R88A-BAT01W battery.
