PC834-XYZ-A

Product Description:

The PC834-XYZ-A from Pacific Scientific lines up with the PC800 - PCE800 Brushless Servo Drives series. This servo drive stands out with a continuous output current of 7.1 A RMS between 25 and 40 °C, which sets it up for heavier factory machines or bits of automation that keep moving for hours at a time. On the command side, this drive uses the SERCOS Network interface, easy for slotting into modern control systems. Everything’s housed tight to deal with pushing motion up to a velocity range of 0 to 21,000 RPM, plenty for motors that spin or reel in at high speed.

Weight clocks in at 4.2 kg, not heavy for installation, and the dimensions come to 254 mm × 146.7 mm × 192 mm, so fitting into a cabinet or drive rack isn’t tricky. Top peak output lands at 21.2 A RMS, letting it manage the pressure when changes in load hit suddenly. Motor phase current rides in a back EMF matched pseudo sine pattern, which works out for quieter operation and steadier performance during back-and-forth drives. Max bandwidth is 1.5 kHz, so control updates land quick, and the motor electrical frequency is kept below 400 Hz, which helps with efficiency over longer shifts. Positioning matters, and this drive offers a position range of ±32,768 rev and position command resolution down at 0.33 arc min, backed by a 24 bits/rev (0.0013 arc min) resolver position resolution.

The build on the PC834-XYZ-A suits machine builders dealing with temperature shifts, as it handles -40 °C to 70 °C easily and resists humidity from 10% to 90% (non-condensing). Put it high up or in rougher corners—altitude up to 1,500 m (5,000 ft) won’t be a problem. Installation is simple if space is tight, since the whole design runs compact and light.
