Product Description:

The PC832-001-T is a brushless servo drive built by Pacific Scientific for use within the PC800-PCE800 Brushless Servo Drives series. It serves as the power interface between a motion controller and a three-phase servo motor, regulating current and voltage so the motor can deliver commanded torque and speed in industrial automation tasks such as indexing tables, packaging axes, and electronic gearing. Overall mass is only 1.9 kg, which helps simplify installation on vertical panels without taking excessive cabinet space.

With a continuous three-phase 240 Vac output capability of 1.1 kW, the drive supplies a steady phase current of 2.7 ARMS to matched brushless motors. Its internal power stage switches at an output ripple frequency of 20 kHz, and the high switching rate lowers noise and improves current loop resolution. For short bursts, it can deliver a peak current of 7.5 A zero-to-peak, and the five-second RMS rating of 5.3 ARMS keeps acceleration reserves available without violating thermal limits. A power stage efficiency of 98% minimizes heat dissipation so the 198.1 mm-high module can be mounted closely in control cabinets. Motor inductances between 4.0 mH and 4 H are supported, allowing the same drive to run both low- and high-inertia servo motor families. Under nominal conditions, the RMS line draw is 4.5 A from a 240 Vac supply.

The shared DC bus can absorb regenerative energy up to 20 J. Above that level, the on-board shunt regulator dissipates surplus power at up to 12.8 kW. External braking resistors may be applied, but the drive restricts their duty cycle to 6% to protect components. A peak output power of 2.25 kW is available when line voltage and current allow, giving headroom for rapid deceleration and overhauling loads. The compact chassis also helps keep enclosure airflow unobstructed.
