Product Description:

The PCE833-001-A brushless servo drive is manufactured by Pacific Scientific as a member of the PC800–PCE800 Brushless Servo Drives series. It supplies the regulated three-phase power required for permanent-magnet servomotors while executing closed-loop velocity and position commands from higher-level motion controllers for coordinated axis control. In industrial automation cells, the drive functions as the interface that translates low-level control words into precise motor currents so conveyors, pick-and-place heads, or index tables maintain accurate trajectories.

At 40 °C, the drive sustains a continuous phase current of 3.75 ARMS, delivering a steady mechanical output of 2.6 kW at 480 VAC. For rapid acceleration, it can furnish a peak value of 7.5 ARMS, which equates to a short-term shaft capacity of 6.4 kW at 480 VAC. Power moves through an IGBT stage whose efficiency is rated at 97%, keeping panel heat dissipation modest. An inrush current of 175 A lasting 1 ms must be accommodated by upstream protection devices, and the aluminum chassis measures 254 × 121.7 × 192 mm while weighing 3.6 kg, so it fits tightly packed multi-axis cabinets. These values describe the continuous operating range and the transient limits that apply before the shunt begins clamping excess bus energy.

Energy management is handled by a 35 J internal absorber and a shunt regulator that can dump up to 10 kW into an external resistor, preventing overvoltage during regenerative braking. The supply draws 5.1 ARMS, and output waveform purity is maintained with a carrier frequency of 16 kHz to minimize motor acoustic noise. Application flexibility comes from the RS-232/485, ±10 V analog, Step/Dir, and Indexing command set, terminated on 15-pin and 44-pin D-sub connectors for quick wiring without additional adapters in standard control panels.
