Product Description:
The PC832-001-A is a brushless servo drive manufactured by Pacific Scientific as part of the PC800 – PCE800 Brushless Servo Drives series. It supplies controlled three-phase current to a matched permanent-magnet motor, closing torque, velocity, and position loops inside the drive itself. In industrial automation cells, this device governs single-axis or multi-axis stages, allowing packaging, pick-and-place, or material-handling equipment to move to commanded points with repeatable accuracy.
During continuous operation, the power section delivers 2.7 A RMS, and it can supply a short-term peak of 5.3 A RMS for five seconds to accelerate loads. Position feedback is processed at 24-bit resolution, so the controller can resolve 16,777,216 distinct positions per revolution before interpolation. A velocity loop bandwidth of 400 Hz allows speed corrections to be issued every 2.5 ms, keeping following error small during rapid changes. Power stage efficiency reaches 98%, reducing panel heat and minimizing the size of required cooling hardware. Command inputs include RS-232/485 serial links, ±10 V analog velocity, step-and-direction pulse trains, and resident indexing sequences, giving several ways to issue motion profiles. The optically isolated inputs draw 24 VDC at 100 mA, and a user supply presents 5 VDC at 200 mA for external sensors.
The encoder interface outputs up to 16,384 PPR, providing a differential quadrature signal for downstream controllers that need position echo. Internal current shaping operates at a ripple frequency of 20 kHz to shift switching noise above typical mechanical resonances. On power-up, the bus capacitors accept an inrush of 300 A peak for 1 ms, and then the drive settles at normal draw. Relay contacts rated for 30 VDC @ 1 A can signal drive fault status or enable external brakes. The unit supports motor leads up to 50 m and accommodates winding inductances from 4 mH to 4 H without instability.
