Festo P.BE−CPX−CMAX−SYS−EN en 0908NH
Intended use
The CPX−CMAX−C1−1 axis controller documented in this
description is intended exclusively for use in Festo CPX
terminals for installation in a machine or an automation
system.
In connection with a CPX terminal with suitable CPX bus
nodes or CPX−FEC, as well as with enabled drives with a
displacement encoder as well as a VPWP propor tional direc
tional control valve, CMAX serves as a position controller with
position and force control for pneumatic drives.
The CPX terminal may only be used with the CMAX as follows:
As intended for the industrial environment
In its original condition without unauthorised modifica
tions. Only the conversions or modifications described
in the documentation supplied with the product are per
mitted.
In perfect technical condition.
Only in combination with approved components
(valves, drive/displacement encoder combinations,
see section 1.2).
The limit values specified for pressures, temperatures, electri
cal data, torques etc. should be observed.
Please comply with regulations of the trade associations,
the German Technical Control Board (TÜV), the VDE or the
relevant national regulations.

VIII Festo P.BE−CPX−CMA X−SYS−EN en 0908NH
Safety note
Protection against dangerous movements
Warning
High acceleration forces at the connected actuators!
Unexpected motions can cause collisions and severe
injuries.
Dangerous movements can occur due to the faulty control
ling of connected actuators, e.g. due to:
Dirty or faulty wiring/cabling
Component operating errors
Measured value and signal generator errors
Faulty or non−EMC−compliant components
Errors in the higher−order control system.
Simply switching off the compressed air supply or load
voltage are not suitable locking procedures. In the event of
a fault, this could lead to unintentional movement of the
drive.
·Before mounting, installation and maintenance work, put
the system into a safe state (e.g. by putting the drive in a
safe position and deactivating the controller).
Always make sure that the compressed air and power
supplies are switched off and locked before working in
the machine area.
·Make sure that no persons are in the operating range of
the drive or any other connected actuators.
·Do not switch on the compressed air until the system is
correctly installed and parameterised.
Contents and general safety instructions
IX
Festo P.BE−CPX−CMAX−SYS−EN en 0908NH
·The holding brakes controlled by the drive controller are
not appropriate for personal protection by themselves.
Lock vertical axes additionally to keep them from falling
down or sinking when the compressed air and load volt
age are switched off, e.g. by means of:
mechanical locking of the vertical axis
external braking/safety catch/clamping device
sufficient counterbalance of the axis.
·If used in safety applications, additional measures are
necessary, e.g. in Europe the standards listed under the
EU machine guidelines must be observed. Without addi
tional measures in accordance with statutory minimum
requirements, the product is not suitable for use in
safety−related sections of control systems.
Protection from pressurised tubing
Caution
Danger of injury through inappropriate handling of pres
surised tubing!
Uncontrolled movements of the connected actuators and
uncontrolled movements of loose tubing can cause injury
to human beings or damage to property.
·Do not connect, disconnect or open pressurised lines.
·The lines must always be exhausted before removal
(release compressed air).
·Use suitable protective equipment (e.g. safety goggles,
safety shoes, etc.).

Glossary
The following product−specific terms and abbreviations are
used in this description:
Term/abbreviation Meaning
0xA0 (A0h) Hexadecimal numbers are marked by a prefixed 0x" or by a subscript
h.".
Absolute position
measuring system
A position measuring system with fixed (absolute) assignment of
the measured value (position, angle, etc.) and measured variable,
for digital" or potentiometer" CMAX.
Adaptation CMAX function to improve non−optimal switch−on behaviour automati
cally during operation
Axis string Totality of all modules and cables which are connected via the axis inter
face to the CMAX
Bus node Establish the connection to specific fieldbuses. Transmit control signals
to the connected modules and monitor their operation (as CPX module:
CPX bus node).
Control interface Connection for all modules and cables in the axis string.
CPX modules Collective term for the various modules which can be integrated in a CPX
terminal.
CPX node Collective term for all CPX bus nodes or the CPX−FEC
CPX terminal Complete system consisting of CPX modules with or without pneumatics.
Drive In this description, the term drive" represents linear drives (DGCI, DGP),
standard cylinders, positioning drives (DNC, DNCI, DNCM) or swivel
modules (DSMI).
Festo Configuration Tool
(FCT)
Software with standardised project and data management for supported
device types. The special requirements of a device type are supported
with the necessary descriptions and dialogues by means of plug−ins.
Festo Handling and Posi
tioning Profile (FHPP)
Fieldbus data profile for Festo position controllers
Festo Parameter
Channel (FPC)
FHPP−specific parameter access

Term/abbreviation Meaning
Functions Special functions in the different operating modes. e.g.:
Jog mode
Homing
Homing By means of homing, the reference position and thereby the origin of the
dimension reference system of the axis are defined.
I Digital input.
From the point of view of the master controller, the CMAX status outputs
are module input data. See section 4.5.
I/Os Digital inputs and outputs.
Identification System function where specific characteristics of the connected axis are
determined by means of an identification run, e.g. break−away forces,
frictional behaviour, dynamics (maximum accelerations and speeds), etc.
Incremental position
measuring system
A position measuring system in which the measured variable refers to a
reference point and is determined by counting equally large measure
ment steps (increments) with the CMAX encoder".
Jog mode Manual travel in positive or negative direction.
Function for setting positions by approaching the target position,
e.g. by teaching records.
Logic 0 Input or output provides 0 V (also LOW, FALSE or logical 0).
Logic 1 Input or output provides 24 V (also HIGH, TRUE or logical 1).
O Digital output
From the point of view of the master controller, the CMAX control inputs
are module output data. See section 4.5.
OB Output byte
Operating mode Type of CMAX control, function or setpoint specification
Parameter Various settings which must be defined for system operation and be
saved in CMAX.
PLC/IPC Programmable logic controller; for short: Controller
(also IPC: industrial PC).
PNU Parameter number each parameter has a number and subindex.
Position control Control mode where a defined position is approached and held with
control.
