Product Description:
The SC903NN-001-01 is a servo drive manufactured by Pacific Scientific and released under the SC900 Servo Drives series. As a closed-loop power stage, it governs brushless servomotors in automated machinery by translating reference commands from a controller into regulated three-phase output. It regulates current, speed, and position in cabinet-mounted industrial motion systems where repeatable axis behavior is required. This unit is a Standard Unit intended for packaging, assembly, and other automated machinery that uses brushless servomotors for controlled movement.
This drive accepts motion references through an analog or incremental digital command interface. It does not include an embedded fieldbus, so commands are provided through its local control interface. Under natural convection at 25 °C, it can supply a continuous output of 7.5 A, while short-term acceleration demands are met with a peak capability of 15.0 A. The drive delivers 2.2 kW of continuous mechanical power when fed from a 240 V three-phase source. A convection-cooled design without a fan removes moving parts from the cooling path and helps keep cabinet airflow requirements low in clean or particulate-sensitive areas. This cooling method also reduces acoustic noise and avoids fan wear during long operating cycles.
Motor matching is supported by a maximum line-to-line inductance of 2 H and a minimum of 2.0 mH, allowing the controller to work with both low- and high-inductance motors without destabilizing the current loop. During rapid indexing, the inverter section can deliver up to 4.5 kW of peak mechanical output, and the power stage operates at an efficiency of 96% to help limit heat inside the cabinet. These characteristics support responsive acceleration, stable current regulation, and steady speed control in applications that alternate between continuous running and short bursts of higher demand. Lower internal heat can also help the drive maintain reliable operation when installed near other control hardware in a compact enclosure.
