This document provides information on various types of controllers for ROBO cylinders. It discusses positioner type controllers like PMEC/AMEC and PSEP/ASEP which can control positioning to 2-3 positions using the same signals as a solenoid valve. It also covers program type controllers which execute programmed instructions to control actuators and communicate with other devices, allowing for high-level control and interpolated motion of multiple axes. The document provides specifications for different controller models and describes their applications.
