CMAX functions
Mode of operation
1−4
The CMAX axis controller, together with a VPWP proportional
directional control valve and a drive with a position measur
ing system, forms a positioning system for pneumatic axes
(see section 1.2).
The positioning system permits:
Travel at selectable speed in any positions (position con
trol)
The approach of a position and applying a defined force
(force control).
Mode of operation
The CMAX takes over the following functions:
Parameter storage (hardware configuration, records, con
troller settings, etc.)
It ascertains system characteristic values of the con
nected components (identification).
Specifies setpoint values (position or force)
Tracks setpoint and actual values (position or force con
trol) by appropriately activating the proportional direc
tional control valve.
The CMAX, valve, drive and displacement encoder are
connected to form a closed−loop control circuit.
