Function and application
2.3.1
Tasks of the CMAX
The CMAX takes over the following functions:
–
storage of all project parameters (e.g. hardware configuration, records, controller settings)
–
determination of system characteristic values of the connected components (identification)
–
specification of the setpoint values (position or force) calculated from the specified target value and
the parameterised movement profile
–
tracking of the actual value (position or force control) in case of deviation through corresponding
control of the proportional directional control valve
2.3.2
Mode of operation
The CMAX, valve, drive and displacement encoder are connected with each other to form a closed-loop.
In combination with a proportional directional control valve VPWP and a drive with a displacement en
coder, the CMAX axis controller forms a positioning system for pneumatic axes (
è
positioning system permits the following:
–
travel at selectable speed with previously configured acceleration in any positions (position control)
–
application of a defined force with configured force edge [N/s] (force control) with simultaneous
speed and position monitoring
