A position controller for actuators, energy monitors or other feedback systems. The CST225 digital controller is designed to control actuators operated by standard AC servo motors.

A feedback signal from a potentiometer, voltage or current, is used to provide the controller with positional information. The reference signal may be entered digitally via the keypad or an optional potentiometer may be used. The LED display provides an accurate indication of performance.

The CST225 provides precise digital selection of speed, position and other variables, using standard AC servomotors or solenoids to operate the controlling actuator.

Using digital frequency comparison, the system compares the reference signal entered at the keypad with a feedback signal from a frequency which relates to the variable being controlled. Interface modules are available to accept feedback signals from potentiometers or voltage and current signals.

The servo motor is switched by relays using an error dependent pulsing technique. Comprehensive programming facilities enable the CST225 to be matched to many different control requirements using the parameter programming facility.
