Product Description:
The SC756A-001-01 is a servo controller produced by Pacific Scientific and included in the SC750 Servo Drives series. In an automation cell, it functions as a closed-loop drive amplifier and motion controller, coordinating brushless servo motors and actuators so they follow programmed positions and velocities. By combining power electronics with embedded control logic, the unit bridges PLC commands and motor windings to provide precise axis regulation in assembly lines, packaging equipment, and material-handling systems. Because motion control and power delivery are handled in one unit, the controller can manage command response, motor commutation, and corrective action within the same platform.
The drive delivers a continuous output of 60 A, allowing it to supply rated torque without thermal drift, while short-term demands are supported by a 120 A peak current reserve during acceleration and shock loading. That reserve helps the axis overcome inertia at startup and respond to abrupt load changes without immediately dropping out of regulation. At maximum output, the inverter stage can deliver 36,000 W to the motor phases, and its internal losses are limited to 600 W. Heat is removed by built-in fans and natural convection, which reduces dependence on external cabinet airflow. The enclosure weighs 40.86 kg, and the +22 arcmin option is intended for applications that require tighter positional accuracy.
Control is handled by a programmable digital position controller that uses resolver feedback, which remains reliable under vibration and electrical noise. Application code is written in PacSci ServoBASIC Plus and stored in a 24K nonvolatile memory block, so the axis can restart with its saved program after power is restored. Stored logic can manage positioning routines, sequencing, and local decision-making for standalone or coordinated axis tasks. For line isolation, the input requires a 10 to 15 kVA step-down transformer. This arrangement allows the controller to run stored motion sequences without depending on a separate host processor.
