Product Description:
The brushless servo drive PCE833-001-T is produced by Pacific Scientific as a member of the PC800 – PCE800 Brushless Servo Drives series. It is intended to supply controlled torque and speed to synchronous motors in automated machinery. Closed-loop control helps the connected motor respond accurately during speed changes and positioning moves. The unit supports automated sequences that require repeatable starts, stops, and controlled speed transitions throughout each production cycle.
This unit can deliver a continuous phase current of 3.75 ARMS and supports momentary demands up to a peak output of 7.5 ARMS; the internal power stage withstands short bursts of 10.6 A zero-to-peak for rapid acceleration. When operated from a 480 VAC supply, it supplies 2.6 kW of continuous mechanical power to the motor, while pulse-width modulation occurs at 16 kHz, which helps limit audible noise and smooth current ripple. Startup draws an inrush of 175 A, so upstream breakers and the recommended KTK-20 20 A fuse must be sized accordingly. A minimum motor inductance of 5 mH is required to keep switching losses within design limits, and the drive’s 5.1 ARMS line current is suitable for three-phase services at 380, 400, or 480 VAC. The housing measures 254 mm high, 121.7 mm wide, and 192 mm deep, allowing side-by-side cabinet mounting with minimal clearance.
During braking, the internal resistor can dissipate 200 W continuously, whereas the energy dump circuit absorbs surges up to 10 kW for quick deceleration of high-inertia loads. Total mass is only 3.6 kg, easing panel installation and reducing vibration loads on DIN rails or chassis plates. The command interface set includes RS-232/485 serial links, a ±10 V analog velocity input, step-and-direction pulse-train control, and stored indexing. This allows the drive to work with legacy controllers and modern bus topologies without external converters, and stored indexing supports repeated local move execution when separate position commands are not sent for every cycle.
