Product Description:
Pacific Scientific produced the SA602-001-01 as part of its SC900 Servo Drives series. This drive provides closed-loop control for brushless servomotors in industrial automation, converting three-phase input power into regulated current so a motion controller can position loads accurately. Designed for cabinet mounting, the unit serves as the power stage between PLC-level commands and motor windings. It delivers the dynamic response required in packaging lines, pick-and-place axes, and general machine tools. The closed-loop architecture allows the drive to regulate motor behavior as operating commands and mechanical loads change.
With natural convection cooling at 25 °C, the power stage can continuously deliver an output current of 3.75 A. When connected to a 240 V three-phase source, the drive supplies a continuous output of 1.1 kW. For short acceleration periods, it allows a peak current of 7.5 A, providing additional torque while remaining within its thermal limits. During these peaks, the instantaneous electrical output reaches 2.2 kW at 240 VAC. The power stage operates at 95% efficiency, so only a small portion of the incoming energy is dissipated as heat. This low heat loss reduces the cooling demand inside the enclosure and allows the unit to operate near sensitive control electronics when proper cabinet clearances are maintained.
Control signals enter through a selectable analog or incremental digital command interface, permitting torque, velocity, or position control through ±10 V references or quadrature step streams. The drive has no internal communications port, so control and setup functions use direct terminal connections rather than a fieldbus. Its current regulators are suitable for motors with a line-to-line inductance of 4.0 mH. Using a compatible motor helps keep current ripple within acceptable limits and supports stable control-loop operation. The available command formats allow the unit to work with controllers that provide either conventional analog references or incremental digital pulses. These connection options are suitable for small-frame rotary stages and other compact motion axes that require responsive motor control.
