Product Description:

The SCE904-002-01 A servo drive is produced by Pacific Scientific and belongs to the SCE900 Servo Drives series. It conditions incoming three-phase power and modulates it according to controller demands, acting as the link between low-level command signals and the torque delivered by a brushless servomotor. By regulating current in real time, the drive maintains precise velocity and position profiles that are essential for automated pick-and-place stages, packaging stations, and material-handling axes on factory floors. This control behavior helps the axis respond smoothly to changing loads during short indexing moves and repeated start-stop cycles.

The amplifier provides a continuous output of 10.6 A at 25 °C, so the motor can run under rated load without overheating. During rapid accelerations the current rises to a peak of 21.2 A, giving extra headroom for inertia-dominated moves or sudden load changes. Command references reach the power stage through an analog or incremental digital command interface, letting the user select either ±10 V velocity loops or quadrature step inputs from an external encoder. The chassis stands 370 mm tall and projects 229 mm into the enclosure, which helps determine internal spacing, airflow paths, and wire-bend radii around the unit.

A front width of 114 mm allows the drive to fit side by side with other modules on a standard panel rail while preserving clearance for cooling airflow. The assembly weighs 6.6 kg, which gives the housing solid thermal mass without making panel installation awkward. Because it is a servo drive, locating it close to the motor helps limit cable impedance and supports stable current-loop response. That arrangement can also reduce the effect of cable inductance on fast current changes during demanding motion profiles. Its enclosure size suits multi-axis panels where several drives must share vertical space without blocking access to adjacent wiring.
