Festo – GDCP-CMMP-AS-M0-S1-EN – 1412a – English 7
1 Safety and requirements for product use
1.1 Safety
1.1.1 General safety information
 In addition, always observe the general safety regulations for the CMMP-AS-…-M0.
The general safety regulations for the CMMP-AS-...-M0 can be found in the hardware
documentation, GDCP-CMMP-M0-HW-... èTab. 2, page 6.
Note
Loss of the safety function.
Non-observance of the environmental and connection conditions may lead to loss of
safety functions.
 Observe the specified environmental and connection conditions, in particular the
input voltage tolerances èTechnical data, Appendix A.1.
Note
Damage to the motor controller due to incorrect handling.
 Switch off the supply voltage before mounting and installation work. Switch on
supply voltage only when mounting and installation work are completely finished.
 Observe the handling specifications for electrostatically sensitive devices.
1.1.2 Intended use
The CMMP-AS-...-M0 motor controller supports the following safety function:
– “Safe torque off ” (STO) with SIL 3 according to EN 61800-5-2 / EN 62061 / IEC 61508 or
category 4 / PL e according to EN ISO 13849-1.
The CMMP-AS-...-M0 motor controller is a product with safety-relevant functions and is intended for
installation in machines or automation systems and for use as follows:
– in excellent technical condition,
– in original status without unauthorised modifications,
– within the product's limits as defined by the technical data èAppendix A.1,
– in an industrial environment.
Note
In the event of damage caused by unauthorised manipulation or other than intended
use, the guarantee is invalidated and the manufacturer is not liable for damages.

1 Safety and requirements for product use
8 Festo – GDCP-CMMP-AS-M0-S1-EN – 1412a – English
1.1.3 Possible incorrect application
The following misuses are among those not approved as intended use:
– use outdoors,
– use in the non-industrial area (residential areas),
– use in applications where switching off can result in hazardous movements or conditions.
Note
– The STO function is insufficient as the sole safety function for drives subject to
permanent torque or force (e. g. suspended loads).
– Bypassing of safety equipment is impermissible.
– Repairs to the motor controller are impermissible!
The STO (Safe Torque Off ) function does not provide protection against electric shock,
only against hazardous movements!
èHardware documentation, GDCP-CMMP-M0-HW-...
1.1.4 Attainable safety level,
Safety function to EN ISO 13849-1 / EN 61800-5-2
The CMMP-AS-...-M0 motor controller with integrated STO safety function fulfils the requirements of
– Category 4 / PL e to EN ISO 13849-1
– SIL CL 3 to EN 62061
and can be used in applications up to cat. 4 / PL e to EN ISO 13849-1 and SIL 3 to EN 61800-5-2 /
EN 62061 / IEC 61508.
The achievable safety level depends on the other components used to achieve a safety function.
1.2 Requirements for product use
 Make this documentation available to the design engineer, installer and personnel responsible for
commissioning the machine or system in which this product is used.
 Make sure that the specifications of the documentation are always complied with. When so doing,
also take into account the documentation for the other components (e. g. motors, cables, etc.).
 Take into consideration the legal regulations applicable for the destination, as well as:
– regulations and standards,
– regulations of the testing organizations and insurers,
– national specifications.
 For emergency stop applications, protection against automatic restart corresponding to the re
quired safety category must be furnished. Among other means, this can take place through an ex
ternal safety switching device.

– the documentation for the product.
1.2.3 Diagnostic coverage (DC)
Diagnostic coverage depends on the connection between the motor controller and the control loop
system as well as the implemented diagnostic measures èSection 5.4.
If a potentially dangerous malfunction is recognised during the diagnostics, appropriate measures
must be taken to maintain the safety level.
Note
Check whether cross-circuit detection of the input circle and the connection wiring is
required in your application.
If necessary, use a safety switching device with cross-circuit detection for activation of
the safety function.
1.2.4 Range of application and certifications
The motor controller with integrated STO safety function is a safety-related part of the control systems.
The motor controller carries the CE mark.
Standards and test values which the product must comply with and fulfils can be found in the section
“Technical data” (èAppendix A.1). The product-relevant EU directives can be found in the declaration
of conformity.
Certificates and the declaration of conformity for this product can be found at

2 Description of the safety function STO
2.1 Product overview
2.1.1 Purpose
As processes become increasingly automated, protecting people from potentially hazardous move
ments is gaining in importance. Functional safety describes the measures offered by electrical or elec
tronic devices that are required to reduce or eliminate malfunction-induced hazards. In normal opera
tion, safety devices prevent human intervention in hazardous areas. In certain operating modes, during
set-up for example, people also need to be in hazardous areas. In such situations, the machine operat
or must be protected by drive and internal control measures.
The functional safety technology integrated in the motor controller provides the conditions required by
the controller and drive for optimised realisation of the safety functions. Planning and installation com
plexity is reduced. The use of integrated functional safety technology increases machine functionality
and availability over the levels achieved by conventional safety technology.
2.1.2 Interface
The CMMP-AS-...-M0 motor controller is equipped with a digital I/O interface [X40] for control of the
STO safety function.
