Product Description:
The SA603-001-01 servo drive is produced by Pacific Scientific and belongs to the SC900 Servo Drives series. The unit functions as the power and current regulator between a motion controller and a three-phase brushless motor, translating low-level commands into controlled motor torque for automated assembly lines, packaging equipment, and other industrial axes. Its control architecture provides precise velocity and position response while maintaining the electrical isolation and thermal management required for continuous factory operation.
With natural convection at 25 °C, the drive can deliver a continuous phase output of 7.5 A, supporting servomotors that draw steady midrange currents during production cycles. At the same ambient temperature and with a 240 V three-phase supply, the continuous electrical power available at the motor terminals reaches 2.2 kW, allowing sustained output without overheating the power stage. For rapid acceleration or transient load events, the current capacity extends to a peak of 15.0 A. The corresponding short-term power capacity reaches 4.5 kW when the mains voltage is 240 VAC. Energy loss as heat is limited because the power section operates at 96% efficiency, which reduces cabinet cooling requirements and helps maintain stable operation during extended duty cycles.
The SA603-001-01 accepts analog or incremental digital inputs, allowing either voltage signals or quadrature step streams to control speed and direction. The drive includes no fieldbus hardware, so motion references and setup commands are handled locally through the available input methods. This arrangement is suitable for systems in which direct controller connections are preferred over network communication. Motor selection must remain within the drive’s supported inductance range to maintain stable current regulation across different winding designs. The permitted window extends from a maximum line-to-line inductance of 2 H to a minimum line-to-line inductance of 2.0 mH. Motors outside this range may not provide the electrical response needed for consistent current-loop performance.
