Product Description:

Pacific Scientific’s SCE952NN-504-01 servo drive belongs to the SCE900 Servo Drives series and operates as the power and control stage between a motion controller and a brushless servo motor in automated machinery. By modulating output current in response to velocity or position commands, the unit maintains precise motor torque, helping coordinate axes in packaging lines, pick-and-place gantries, and other industrial positioning tasks. It integrates drive electronics, signal processing, and field wiring into a single chassis suited for cabinet mounting.

During continuous operation at 25 °C, the drive supplies 3.75 A of motor phase current, a steady-state level selected to match mid-frame servomotors without overheating. For brief accelerations, it can deliver a peak of 7.5 A, doubling available torque to overcome inertia during rapid starts and stops. Heat produced by the output stage is removed through convection cooling with no fan, so no moving parts are added to the enclosure and acoustic noise stays low. Cabinet depth of 229 mm and height of 370 mm define the installation space and airflow clearances around the heat sink. Command execution is managed by a single-axis programmable positioning interface that receives incremental motion profiles and closes the position loop locally, reducing network traffic.

The controller logic is carried on an OCE950 128Kx8 NV RAM option board; its nonvolatile memory preserves application parameters when power is removed, allowing the drive to retain setup data between power cycles. The drive uses the Standard version, which supports homing routines, jog modes, and electronic gearing without custom code. The product is released for use only when a system provides Command Interface 5, ensuring that cabling, protocol levels, and safety interlocks align with the SCE900 signal map.
