Product Description:

The PC834-XYZ-T is a brushless servo drive produced by Pacific Scientific within the PC800–PCE800 Brushless Servo Drives series. It is intended for motion control systems that require precise regulation of permanent-magnet servomotors on automated assembly lines, packaging cells, and material-handling axes. Acting as the interface between a three-phase 240 VAC mains supply and the motor, the drive converts line energy into controlled, low-ripple current while monitoring feedback to keep commanded speed and torque within programmed limits. This arrangement supports consistent axis response during repeated starts, stops, and speed changes.

Under nominal loading, the power stage can deliver a continuous output of 3.0 kW when fed from a 240 VAC three-phase bus. With natural convection, the drive supplies 7.1 ARMS, and installing a blower raises the available phase current to 10.6 ARMS. The drive draws approximately 12 A from the mains during steady operation, and the internal IGBT power stage operates at an efficiency of 98%, which helps reduce cabinet heat. The housing measures 198.1 mm in height, 158 mm in depth, and 114 mm in width, so it fits narrow panels while still allowing the airflow clearance needed around nearby control hardware.

For short-term acceleration, the hardware supports a peak output of 9.0 kW, and the current regulator can produce a momentary inrush of 300 A for 2 ms before returning to continuous operation. The vector controller also provides 30 A peak-to-peak at the motor terminals and up to 21.2 ARMS on a root-mean-square basis during brief bursts, provided the source does not exceed the 250 kVA AC line limit. The unit weighs 2.6 kg, which keeps handling straightforward during installation in ventilated racks. Operation is permitted at elevations up to 1500 m without derating when the mounting conditions provide proper ventilation, and that makes the drive suitable for a wide range of industrial cabinet locations.
