Selection Guide
Festo offers actuators with feedback, both rotary and linear. The linear potentiometer is a component of the controlled systems—it supplies the actual value with the current position. Potentiometers or contactless linear potentiometers are used. The linear potentiometers are integrated in many pneumatic actuators. Alternatively, they can also be attached to the actuator. The cylinder diameters vary from 18 mm to 100 mm, the stroke lengths from 100 mm to 2,000 mm.
Festo has two servopneumatic axis controllers in its range: the Soft Stop CPX-CMPX offers fast travel between the mechanical end stops of the cylinder, moving gently and without impact into the end position. In addition, two freely programmable mid-positions are available. Fast commissioning is done via control panel, fieldbus or handheld terminal.
The new position controller CPX-CMAX is designed for simple servopneumatic control of various pneumatic drive families, linear or rotary. The CPX-CMAX is a positioning and force control module of the modular electrical terminal CPX.
The linear potentiometer in a servopneumatic positioning system is used to detect the actual position. Festo offers potentiometers for attachment to pneumatic actuators. They are characterized by their low price and their resistance to welding currents. Magnetostrictive linear potentiometers are contactless and have absolute measurement. They can be installed in pneumatic actuators or mounted externally.
An encoder system is installed in the ISO cylinder DNCI. It is contactless and must be homed when the supply voltage is switched on.
The flow-proportional 5/3-way valve VPWP serves as a final control element in the servopneumatic positioning system. It enables the speed to be controlled. The force is controlled by integrated pressure sensors. Four different flow variants are available, each adapted to the cylinder size.
A sensor interface is used wherever the measuring signal has to be converted into the internally used CAN signal. This is the case with potentiometers and DNCI cylinders.
