Product Description:

The PC832-XYZ-T brushless servo drive is produced by Pacific Scientific as part of the PC800-PCE800 Brushless Servo Drives series. It converts three-phase mains power into a regulated DC bus and variable-frequency output for precise speed and torque control of brushless servo motors in automated machinery. Machines that involve packaging, pick-and-place, or indexing tables use the drive to synchronize axes without mechanical gearing.

For installations on a 240 VAC three-phase supply, the internal rectifier establishes a bus of 320 VDC. Control electronics accept a wide auxiliary supply of 85-265 VAC at 47-440 Hz, so the unit can share low-power service transformers on mobile or offshore equipment. Under continuous duty, the inverter delivers 2.7 ARMS, translating to 1.1 kW of mechanical shaft power when paired with motors in the stated range. A switching frequency of 20 kHz reduces torque pulsation and audible noise. The command interface offers RS-232/485 serial links for parameter access, a ±10 V analog channel, step-and-direction pulses, and internal indexing cycles, making the drive adaptable to legacy PLCs and modern motion controllers. Dimensions are 198.1 × 88.1 × 158 mm and the enclosure weighs 1.9 kg, which helps conserve cabinet space.

During transient events, the drive can source 5.3 ARMS, supporting short acceleration demands up to 2.25 kW. Power stage efficiency remains at 98%, limiting thermal load and allowing natural convection. Resolver feedback is processed at 24 bits/rev, giving fine electrical angle resolution for smooth commutation. Motor cabling may run up to 50 m, and the design accommodates inductances from 4.0 mH to 4 H, so a broad family of Pacific Scientific brushless motors, along with others in the same winding range, can be connected. The DC bus is energized from the machine's three-phase network, while the separate control supply supports the drive electronics.
