Product Description:

The PC833-XYZ-T is a brushless servo drive produced by Pacific Scientific and supplied in the PC800 – PCE800 Brushless Servo Drives series. It converts fixed mains energy into a regulated DC bus and three-phase output so that motion controllers can manage torque, speed, or position on connected servomotors used in automated packaging, handling, and assembly cells. The unit is intended for machine axes that require closed-loop motion control and stable response during repeated operating cycles.

During continuous duty, the drive draws power from a three-phase 240 VAC line and develops a DC link stabilized at 320 VDC. From that bus, it can deliver a sustained phase current of 3.6 ARMS, equal to 1.5 kW of mechanical output when paired with a matched motor. The transistor bridge is pulse-width modulated at 20 kHz, a frequency that limits audible noise while reducing torque ripple. At nominal load, the power stage returns 98% electrical efficiency, minimizing panel heat and line current demand. Thermal design supports 6 A of RMS line draw and accommodates motors whose phase-to-phase inductance spans 2.0 mH to 2 H without additional reactance. Physical dimensions measure 198.1 mm in height, 88.1 mm in width, and 158 mm in depth, allowing side-by-side mounting in compact cabinets.

For transient moves or rapid acceleration, the current limit rises to 10.6 ARMS, letting the inverter supply up to 4.5 kW of peak motor power for short intervals without shutdown. Motor leads may extend as far as 50 m, a distance suited to distributed axes on large machines when paired with appropriate shielding. Control data reaches the drive through a multi-mode interface that includes RS-232/485, ±10 V analog velocity, step-and-direction pulses, and internal indexing, so the control method can match the connected PLC or motion card. The fixed ripple frequency and internal bus architecture help reduce cable-borne EMI while keeping the module compatible with other PC800 units.
