Pacific Scientific SCE903A3-002-01 Servo Drive

The Pacific Scientific SCE903A3-002-01 is a high-performance digital servo drive from the SCE900 series. It is designed to control brushless AC servo motors and permanent magnet motors in demanding industrial automation applications. The drive features a modular design with a removable option card for flexible configuration, a digital signal processor (DSP) for precise current, velocity, and position control, and support for 230-400 VAC 3-phase power systems.

Digital Control and Performance

The SCE903A3-002-01 uses a dedicated DSP to close the current, velocity, and position loops in software. All system parameters are set digitally, ensuring repeatability and eliminating drift. The drive's autotuning feature automatically optimizes performance based on the specific motor characteristics. The IGBT PWM power stage minimizes audible noise and improves efficiency. The seven-segment status display provides diagnostic information and fault codes, simplifying troubleshooting.

Flexibility and Integration

The modular design allows users to install optional communication cards (e.g., SERCOS) for multi-axis synchronization over fiber optic networks. The drive can be configured as a stand-alone unit or integrated into a larger motion control system. It is compatible with Pacific Scientific's family of brushless AC servo motors. The drive is CE-marked and supports worldwide applications.

Application Domains

The SCE903A3-002-01 is ideal for: machine tool axes (milling, turning, grinding); robotic joints (articulated, SCARA, Cartesian); packaging and material handling; printing and converting machinery; test stands and simulation equipment; and medical devices (CT scanners, surgical robots).
