Product Description:

The SCE903-001-01A is manufactured by Pacific Scientific and belongs to the SCE900 Servo Drives series. As a servo drive, it receives low-level motion commands and modulates three-phase power so a connected brushless motor can follow programmed speed or position profiles in assembly lines, pick-and-place stations, and indexing tables. Closed-loop current regulation supports high-bandwidth torque control, which keeps positional error minimal during rapid load changes.

The drive accepts commands through a dual-mode interface for analog or incremental digital command signals, giving control systems the choice of ±10 V velocity references or step-and-direction pulse trains. Under continuous duty at 25 °C, it delivers 5.3 A of phase current, establishing the thermal limit for sustained motor torque. During acceleration or short shock loads, the current regulator can reach a peak of 10.6 A for limited intervals, allowing faster cycle times without requiring an oversized motor. The cabinet depth is 229 mm, while the height of 370 mm provides space for the power section, signal conditioning, and protective circuitry without external add-ons. These dimensions simplify the arrangement of multiple axes in a single enclosure while preserving space for airflow around each drive.

A front width of only 85 mm lets the unit share DIN rails or backplates with contactors and relays in narrow panels. Its mass of 5.0 kg reduces the load placed on swing-out frames or slide-in racks. The enclosure follows the conventions of the 900 Series, so its mounting hole pattern and connector locations align with companion models across the power range. This common layout supports orderly power and signal routing when several drives are installed on the same backplate. Consistent markings and diagnostic LED placement make operating conditions easier to identify during routine fault checks.
