1.1.2 CMAX function
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
CMAX functions 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.
Mode of
operation The CMAX, valve, drive and displacement encoder are
connected to form a closed−loop control circuit.
