Product Description:
The SCE903N3-000-01 is manufactured by Pacific Scientific and belongs to the SCE900 Servo Drives series. It functions as the power stage between a motion controller and a brushless servomotor, shaping commanded torque or speed so that automated conveyors, pick-and-place heads, or indexing tables stay on profile. The unit fits standard control cabinets and supports multi-axis installations that require tight following error and quick dynamic response. This arrangement lets the controller handle motion commands while the drive regulates motor output at the axis.
During continuous operation at 25 °C, the power section delivers 5.3 A of phase current, which is the thermal design point for motor and cable sizing. For short acceleration or disturbance events, it can supply up to 10.6 A, giving extra headroom for rapid starts or load shocks without saturating the drive. Command signals are accepted as analog or incremental digital commands, so the same hardware can be directed by ±10 V references or by quadrature encoder streams from a motion controller. The control software uses the factory-issued Standard release, providing the baseline parameter set for velocity, torque, and current loops without application-specific macros. The unit is part of the broader 900 Series, which matches the accessory and mounting format used across the line.
Cabinet planning is simplified by a front plate width of 85 mm, a depth of 229 mm, and a vertical height of 370 mm. These dimensions allow side-by-side stacking in 200 mm deep enclosures while keeping clearance for airflow above the heat sink. The drive has a mass of only 5.0 kg, so it can be mounted without special lifting equipment and does not require reinforced DIN rails. Its compact form also helps maintain orderly cable routing when several axes are installed in one cabinet.
