Product Description:
The SC902AN-001-01 servo drive is manufactured by Pacific Scientific and belongs to the SC900 Servo Drives series. This standard unit uses the standard base servo software for closed-loop motion control in automated machinery. It provides torque, velocity, and position control for brushless servo motors on axes that require consistent speed regulation and accurate positional response. Its operating profile suits compact automation equipment where a dedicated servo amplifier is needed for repeatable motion.
With a continuous output current of 3.75 A at 25 °C under natural convection and a continuous power capability of 1.1 kW when supplied from a 240 V three-phase line, the drive can support moderate-duty axes without forced cooling. The power stage operates at 95% efficiency, so most input energy is delivered to the motor rather than being lost as heat during normal operation. For rapid accelerations, the power electronics can deliver a peak output current of 7.5 A, which corresponds to a short-term mechanical power of 2.2 kW at 240 VAC and helps the axis overcome inertia or friction spikes. This combination of continuous and peak capability allows the drive to handle steady motion as well as brief demand increases during starts and directional changes.
Command signals arrive through an analog or incremental digital interface, and the drive does not use fieldbus communications. The unit is convection cooled and has no fan, so heat must be managed through cabinet layout and surrounding airflow in tightly packed panels. To support stable current regulation, the drive can be matched with motors that have phase-to-phase inductance from 4 H down to 4.0 mH. This motor-matching range allows the amplifier to work with different winding characteristics while maintaining controlled response across a range of brushless servo applications.
