Product Description:

The SC752A-001-01 is a servo controller manufactured by Pacific Scientific as part of the SC750 Servo Drives series. It functions as a programmable digital position controller for industrial automation cells that require coordinated motion on brushless servo axes. The unit regulates torque, speed, and position loops while linking motion sequences to PLC or embedded control logic, making it suitable for repeatable indexing, positioning, and transfer tasks.

This drive supplies a continuous output of 3.8 A and can reach a short-term peak of 7.5 A to start or decelerate loads without stalling. When power demand rises, it can deliver up to 2200 W at the motor terminals, while internal circuitry limits thermal stress through a maximum dissipation of 45 W. Heat is removed by natural convection, which eliminates the need for forced-air components and helps simplify cabinet layouts. Positioning performance in electronic gearing or camming routines can be supported by an optional mechanical tolerance of ±22 arcmin. These electrical and thermal ratings describe the normal operating range of the standard unit.

Command loops close through resolver feedback, allowing the controller to withstand electrical noise common in factory environments. Application code is authored in PacSci ServoBASIC Plus, and the module carries 24 K of non-volatile user memory so motion programs remain stored locally and can run without a host PC. A transformer rated at 3 KVA is recommended to match inrush characteristics and provide isolation to upstream mains during operation. The housing weighs 5.9 kg, which supports panel mounting without additional reinforcement. Local program storage and resolver-based control allow the unit to handle motion tasks directly within the drive rather than relying on a separate external controller for every routine.
