Internal Product Review
The PC842-001-N is a Pacific Scientific brushless servo drive that integrates cleanly on a SERCOS Network for precise machine control. High 98% efficiency and 1.1 kW continuous power support cool, stable operation in demanding automation panels. A 2.25 kW peak output with 5.3 ARMS peak current makes the PC842-001-N a strong performer for dynamic servo duty.

Product Description:
The PC842-001-N is a brushless servo drive manufactured by Pacific Scientific and supplied within the PC800 – PCE800 Brushless Servo Drives series. It is intended to regulate torque, speed, and position of compatible servo motors in automated machinery, linking the motion axis to higher-level machine controls through its network interface and internal power stage. This arrangement lets the unit serve as both the control and power stage for a single servo axis. The enclosure measures 198.1 mm in height, 88.1 mm in width, and 158 mm in depth, giving a compact footprint for multi-axis panels.
This model communicates over the SERCOS Network, allowing deterministic fiber-optic motion commands and diagnostic feedback. During continuous operation, the power stage delivers up to 2.7 ARMS of output current, which supports 1 Nm-class motors without thermal derating. At the same duty point, the drive provides 1.1 kW of electrical power while maintaining an energy conversion efficiency of 98%, reducing cabinet cooling requirements. A stiff DC link held at 320 VDC is produced from a three-phase 240 V supply. The drive uses a 20 kHz switching frequency to keep motor acoustics low and torque ripple minimal, and a 2.25 kW power reserve supports short bursts above the continuous rating.
An inrush limiter is sized for currents up to 300 A, guarding upstream breakers when the DC bus charges. The power terminals permit a motor cable length of up to 50 m, allowing the actuator to be mounted farther from the drive without additional output filters. Winding protection is maintained so long as the connected motor has at least 4 mH of inductance, matching the drive’s current-loop bandwidth. For rapid indexing or emergency moves, the amplifier can supply a peak output of 5.3 ARMS. The housing weighs 1.9 kg, which helps keep installation loads low in compact control enclosures.
