Product Description:

The PC832-102-N-4122-11 is a brushless servo drive manufactured by Pacific Scientific for the PC800-PCE800 Brushless Servo Drives series. The unit converts AC line power and incoming control commands into regulated currents that drive permanent-magnet servomotors used in positioning tables, feeders, and packaging axes. It is intended for motion systems that need stable speed and torque control during repeated positioning cycles.

This unit delivers a continuous output current of 2.7 ARMS, which is the steady-state current for maintaining rated motor torque without thermal overload. For brief accelerations, it can source up to 5.3 ARMS, providing extra thrust during indexing moves. The drive’s power section is rated for 2.25 kW of peak output, so motors can be started or decelerated rapidly. Internal switching devices operate with a power-stage efficiency of 98%, keeping heat losses low and reducing cabinet cooling needs. Control electronics are supplied from a wide auxiliary range of 85-265 VAC, so a separate low-voltage transformer is not required in multi-voltage plants. The power input accepts one- or three-phase mains, and the motor side tolerates inductances between 4.0 mH and 4 H, making the drive adaptable to both low- and high-inductance windings.

The main bus for the power section accepts line voltages from 90-265 VAC, supporting worldwide 120 V or 230 V supplies without tap changes. During regenerative braking, the integrated shunt resistor can absorb transients up to 12.8 kW, protecting upstream equipment from overvoltage. Current is switched at an output ripple frequency of 20 kHz, which places switching noise above the audible range and minimizes torque pulsation. Motion commands are accepted through the multiprotocol port listed as RS-232/485, ±10 VDC, Step/Dir, Indexing, enabling either analog velocity control or digital position pulses. The housing measures 198.1 mm in height, 88.1 mm in width, and 158 mm in depth, yet weighs only 1.9 kg, allowing dense installation inside control enclosures.
