Product Description:

The SCE905-001-01 A is a servo drive released by Pacific Scientific and assigned to the SCE900 Servo Drives series. Acting as the link between a motion controller and a brushless motor, it turns low-level command signals into regulated three-phase power so production lines, pick-and-place stations, and indexing tables keep accurate speed and position. Within automated cells, it occupies the role of a dedicated current regulator, delivering the torque bandwidth needed for repeatable motion while protecting the motor from overcurrent and thermal stress. This control approach helps the axis respond cleanly to changing loads during starts, stops, and direction changes.

At a 15.9 A continuous phase current rating at 25 °C, the drive supports stable operation during steady loads such as conveyor tracking or coating passes. For short intervals, it rises to a peak of 31.8 A, a margin used to clear static friction or accelerate heavy tooling without loss of synchronism. The command stage accepts Analog ±10 V references or incremental digital quadrature pulses, allowing direct connection to common PLC motion modules. Mechanical layout is simplified by its 229 mm depth, which lets the power section sit flush in shallow panels while still leaving room behind for airflow and cable bends.

Front-panel width is 160 mm and overall height measures 370 mm, dimensions that align with standard 19-inch racks and leave clearance for line reactors above and below the chassis. The aluminum housing weighs 9.5 kg, permitting one-person installation while supplying enough mass to absorb switching losses and conduct heat to the cabinet wall. Its proportions also help keep front access organized when the drive is mounted beside neighboring control hardware in a rack. All current ratings assume an ambient of 25 °C, so applications running in warmer enclosures must add forced air or derate the continuous output to preserve device longevity and maintain consistent servo stiffness.
