Product Description:

The PC832-111-N-4122-11 is a brushless servo drive manufactured by Pacific Scientific as part of the PC800–PCE800 Brushless Servo Drives series. Acting as a closed-loop power stage, it meters current to a permanent-magnet servomotor and exchanges feedback with a motion controller to position machinery, conveyors, and packaging axes. Inside an automation cell, the drive converts the plant’s three-phase supply into a variable voltage and frequency output so motor torque and speed follow programmed trajectories with high accuracy. Feedback processing also helps the axis respond predictably to changing load conditions during positioning and speed control.

Continuous operation on a 240 V three-phase bus is supported by a continuous power rating of 1.1 kW, delivered through a regulated phase current of 2.7 ARMS. The internal DC link stores 20 J of energy, allowing the bus to ride through brief load transients. A carrier at 20 kHz limits audible noise while preserving current-loop bandwidth. During acceleration, the inverter can produce a peak current of 7.5 A zero-to-peak, or 5.3 ARMS for short bursts. The shunt regulator dissipates 800 W continuously and protects the bus when external regeneration reaches a 6% duty cycle. Compatible motors must present inductance between 4.0 mH and 4 H so current ripple stays within the intended operating range.

For rapid indexing moves, the drive can supply 2.25 kW to the load and absorb regenerative surges up to 12.8 kW through its dynamic brake path. Motor leads may extend to 50 m, which supports remote motor placement across large production lines without exceeding reflected capacitance limits. The aluminum housing measures 88.1 mm in width, with a depth of 158 mm and a height of 198.1 mm, so it fits standard two-column control cabinets. The compact enclosure supports dense panel layouts, and the permitted cable reach allows the control cabinet and motor to be installed with greater separation when machine geometry requires it.
