Product Description:

The SC755B-001-02 servo controller is produced by Pacific Scientific and belongs to the SC750 Servo Drives series. As a programmable digital position controller, the unit issues high-resolution current pulses that align motor shaft position with the commanded profile, making it suitable for indexing tables, pick-and-place arms, and cut-to-length stations. Within an automation cell, it acts as the intermediary between the motion program and the mechanical axis, providing velocity, acceleration, and settle-time control without the need for additional hardware.

The drive delivers a continuous phase current of 30 A, giving the connected servo motor a steady torque margin for long duty cycles. During acceleration or shock loading, it can rise to a peak output of 60 A, and this surge is matched by a short-term power capability of 18000 Watts. Thermal energy created under these conditions is removed through natural convection with built-in fans, which helps limit derating in closed cabinets. Position feedback is handled with resolver feedback, allowing rotor angle detection even in electrically noisy environments. The internal motion sequencer accepts programming through front-end software, so no external indexer is required.

Power loss inside the control section is limited to 300 Watts, so a transformer in the range of 5 to 7.5 kVA is recommended to keep line voltage within tolerance while supplying auxiliary loads. The option board uses components selected to keep positional deviation within +4 arcmin, providing adequate precision for most material-handling axes. With a mass of 18.16 kg, the unit can be panel-mounted without reinforcing standard 19-inch racks. It is shipped as a standard unit, and the diagnostic LEDs and I/O headers described for the SC750 series are included from the factory.
