Product Description:

The SCE903-001-1A servo drive is produced by Pacific Scientific for the SCE900 Servo Drives series. This digital amplifier regulates current and velocity loops for brushless servomotors in automated machinery, converting motion commands from a controller into controlled three-phase power. By delivering precisely timed switching patterns, it supports packaging lines, assembly stations, and materials-handling cells that require accurate speed and position control. As a general-purpose servo drive, it pairs with permanent-magnet motors to close torque, velocity, or position loops through external feedback.

Continuous output capability at 25 °C is 5.3 A, which is the sustained motor phase current the drive can provide without exceeding thermal limits. For rapid acceleration or disturbance rejection, its peak current rating climbs to 10.6 A for short intervals, providing additional torque before foldback protection engages. Motion commands enter through a selectable interface that accepts analog or incremental digital command signals, allowing compatibility with legacy ±10 V sources or incremental digital streams. The cabinet has a depth of 229 mm, leaving room inside the chassis for heat sinks, power electronics, and filtering components.

The control logic uses the standardized footprint of the 900 Series, providing a consistent physical layout for integration with related drive equipment. The unit has an overall height of 370 mm, while the front panel measures 85 mm wide, allowing it to conserve rack space next to power supplies, PLC modules, and contactors. Its aluminum chassis and magnetic components contribute to a total mass of 5.0 kg, and the housing provides rigid support for the internal power and control assemblies. The narrow enclosure allows adjacent cabinet components to remain accessible for wiring and inspection. Mounting points on the chassis secure the drive within an industrial control cabinet and help maintain stable alignment with connected cable runs.
