Product Description:
The SCE903AN-002-01 servo drive is produced by Pacific Scientific within the SCE900 Servo Drives series. It works as a power amplifier for brushless servomotors, converting motion commands into regulated three-phase current that controls torque and speed. Current regulation, velocity control, and fault monitoring are combined in one package, so the unit supports deterministic axis control in packaging systems, material-handling equipment, and general factory automation. That arrangement lets one drive manage motor operation and protective supervision without requiring separate external monitoring modules.
At 25 °C, the drive can deliver a continuous output of 5.3 A rms, which is suitable for mid-frame rotary motors used in pick-and-place heads. For rapid index moves, it can supply a peak current of 10.6 A for several seconds, allowing the motor to overcome static friction during acceleration. Thermal management relies on a convection-cooled chassis with no fan, so heat leaves the aluminum housing through natural airflow without filters or moving parts. Command information reaches the drive through a selectable analog or incremental digital command interface, allowing it to follow ±10 V speed references or step-direction signals from PLC motion cards. Despite its output capability, the aluminum chassis weighs only 5.0 kg, which helps limit panel loading.
The rectangular enclosure is 229 mm deep, 370 mm high, and 85 mm wide, so it fits standard 300 mm cabinet rails while leaving room for cable bend radius at the rear connectors. Its narrow profile helps it fit alongside adjacent drives in multi-axis cabinets without taking excessive horizontal panel space. Rear connector placement keeps command and power wiring grouped on one face of the unit, which supports orderly cable routing in compact control enclosures. The enclosure shape also suits stacked cabinet layouts where consistent device spacing is needed.
