Product Description:

The PC834-106-N is a brushless servo drive produced by Pacific Scientific as part of the PC800–PCE800 Brushless Servo Drives series. Designed to regulate torque and velocity in permanent-magnet servomotors, the unit forms the power stage between motion controllers and rotary or linear axes in automated machinery. Its control electronics translate command-level signals into high-frequency three-phase current, enabling precise positioning and speed regulation in packaging cells, material-handling gantries, and other industrial automation tasks.

Electrical operating limits describe how the drive interacts with attached motors and upstream supplies. The command section accepts multiple control methods through RS-232/485, ±10 Vdc, Step/Dir, Indexing, allowing both serial setup and hard-wired motion profiles. Under continuous load, the power section delivers 7.1 ARMS, while short bursts up to 21.2 ARMS provide extra acceleration torque. These currents are sourced from a DC link maintained at 320 VDC, and at this level the PWM output is modulated at 16 kHz to reduce audible noise and current ripple. Protective controls monitor thermal and electrical stress so rated values are not exceeded during dynamic duty cycles.

Input protection is handled by a replaceable 30 A, 250 V fuse and by surge-limiting circuitry that caps energization to an inrush current of 300 A for a 2 msec pulse, helping prevent nuisance tripping of upstream breakers. Motor selection must respect a minimum winding inductance of 1.25 mH, while designs up to 1 H are supported to maintain stable current regulation across a broad torque range. The aluminum base anchors a 2.6 kg chassis to a thermally conductive panel. Overall dimensions of 198.1 mm in height, 114 mm in width, and 158 mm in depth simplify cabinet layout without sacrificing power density.
