Product Description:
The SC403-013-T2 is a brushless servo drive produced by Pacific Scientific for the SC400 Servo Drives series. It regulates torque, velocity, and position of compatible servomotors, converting a fixed three-phase AC supply into a controlled DC bus and pulse-width-modulated output. In automated machinery, the drive sits between the motion controller and the motor, executing current loops fast enough to keep axes synchronized while also reporting faults back to higher-level control.
The internal DC link is maintained at 320 VDC; this voltage provides the energy reservoir from which the inverter section draws during acceleration or load changes. A continuous output capability of 7.5 A is the maximum root-mean-square phase current the drive can deliver without exceeding thermal limits, while the matching continuous mechanical rating of 2250 W at 230 V three-phase indicates how much shaft power can be supplied continuously. Current regulation unfolds inside a control loop that reaches a bandwidth of 3 kHz, so the drive can suppress disturbances and track command changes quickly. For short moves or shock loads, the inverter permits a peak phase current of 15 A, enabling rapid torque bursts that exceed the continuous rating for several hundred milliseconds without damage.
When commanded torque is static, the converter’s switching pattern introduces output ripple centered on 15 kHz, placing electromagnetic noise above most audible ranges. The unit can source a fault signal through a 25 mA sink output at up to 30 VDC, providing a dry-contact-style interface for programmable logic controllers that need immediate shutdown notification. During velocity mode, a ±10 V analog command proportional to speed is monitored against a tachometer with a gradient of 1.0 V/krpm, which keeps feedback sensitivity aligned with standard motion controllers. Under full overload, the electrical section supports 4500 W of mechanical output, doubling the continuous figure for rapid indexing without sacrificing long-term reliability.
