Technical details and manufacturing context for Control Unit (PLC or dedicated controller)

Definition
A control unit, typically implemented as a Programmable Logic Controller (PLC) or dedicated controller, serves as the computational core of a force control system. It receives input signals from sensors, processes control algorithms, and outputs commands to actuators to precisely regulate force application in industrial processes. Within force control systems, it manages parameters such as force setpoints, ramp rates, hold times, and safety limits.
Working Principle
The control unit operates by continuously monitoring force feedback from sensors, comparing it to programmed setpoints, and executing PID or other control algorithms to adjust actuator outputs. It processes digital and analog I/O signals, runs sequential control programs, and communicates with HMI interfaces and higher-level systems to maintain precise force control throughout the operational cycle.
