Safety
WARNING
Risk of injury from electric shock in the event of incomplete insulation at the
power connections [X6A], [X9A] and [X9B].
Before operating, plugging in or unplugging the operator unit CDSB or a con-
nector from a hot-plug-capable interface, the following points must be fulfilled:
• The conducting lines at the device are completely insulated.
• The protective earthing (PE) and the shield connection are correctly connected
to the device.
• The housing is free of damage.
WARNING
Severe, irreversible injuries from accidental movements of the connected
actuator technology.
Unintentional movements of the connected actuator technology can result from
exchanging the connecting cables of a servo drive or between servo drives.
• Before commissioning: All cables must be correctly assigned and connected.
WARNING
Risk of injury from electric shock.
Contact with live parts at the power connections [X6A], [X9A] and [X9B] can result
in severe injuries or death.
• Do not pull out power supply plugs while live.
• Before touching, wait at least 5 minutes after switching off the load voltage to
allow the intermediate circuit to discharge.
NOTICE
During commissioning: Keep the range of movement of the connected actuators
clear, so that no persons are endangered.
NOTICE
Unauthorised Access to the Device Can Cause Damage or Malfunction.
• When connecting the device to a network, protect the network from unauthor-
ised access.
Standards for security in information technology can be used for network pro-
tection measures, e.g. IEC 62443, ISO/IEC 27001.
Use of the safety functions
NOTICE
The safety sub-functions STO and SBC are already available on the CMMT-AS
on delivery without the need for any additional parameterisation. Prior to initial
commissioning, you must – as a minimum – wire safety sub-functions STO and
SBC.
1. Make sure that each safety function of the system is analysed and validated.
It is the responsibility of the operator to determine and verify the required
safety classification (safety integrity level, performance level and category) of
the system.
2. Put the servo drive into operation and validate its behaviour in a test run.
During integration of the PDS, observe the measures stipulated by standard
EN ISO 13849-1, Chapter G.4:

Preparation for commissioning
For initial commissioning, you will need to have the Festo Automation Suite
software installed along with the CMMT-AS plug-in
Prepare for commissioning as follows:
1. Check the wiring of the CMMT-AS.
With the CMMT-AS-...-MP, check the switch setting for the selection of the bus
protocol
2. Install the Festo Automation Suite plus CMMT-AS plug-in on the PC.
3. Create a project and add CMMT-AS device.
4. Establish the connection to the CMMT-AS and set network configuration.
5. Identify the technical data of the components that is required for configura-
tion.
8.3
Commissioning steps
NOTICE
Unwanted drive movements or damage to components.
Incorrect parameterisation may result in unwanted drive movements or overload
when the closed-loop controller is enabled or may lead to connected components
becoming overloaded or damaged.
• Do not enable the closed-loop controller until the configured components
(servo drive, motor, axis, etc.) match those that are connected exactly.
During initial commissioning with the Festo Automation Suite with the CMMT-AS
plug-in installed, the following steps must be performed, for example:
1. Perform configuration and parameterisation with the CMMT-AS plug-in (hard-
ware configuration, critical limits and parameters).
2. If the safety function is being used, check functioning of the safety functions
è
Manual Safety sub-function.
3. Check signal behaviour of the digital inputs/outputs (e.g. limit/reference
switch).
4. Provide required control signals.
5. Check direction of rotation/direction of travel of the electromechanical drive
(e.g. in jog operation).
6. Carry out homing.
7. Test positioning behaviour (test mode,
è
help for the CMMT-AS plug-in).
8. If necessary, optimise controller setting (optional,
è
help for the CMMT-AS
plug-in).
9. Perform fieldbus configuration and test control profile (
è
description of the
device profile used).
10. Complete commissioning (e.g. save project with Festo Automation Suite and
archive project).

Operation
Check the safety functions at adequate intervals for proper functioning. It is the
responsibility of the operator to choose the type and frequency of the checks
within the specified time period. The manner in which the test is conducted
must make it possible to verify that the safety device is functioning perfectly in
interaction with all components. Time period for cyclical test
data, safety engineering.
The CMMT-AS is maintenance-free during its period of use and specified service
life. The test interval varies from one safety sub-function to another:
–
STO: no test has to be carried out during the period of use, but we recommend
evaluating STA whenever the sub-function is requested to ensure maximum
diagnostic coverage and the highest safety-related classification.
–
SBC: cyclical test required at least once every 24 h and SBA evaluation rec-
ommended whenever the sub-function SBC is requested to ensure maximum
diagnostic coverage and the highest safety-related classification.

Cleaning
WARNING
Risk of injury from electric shock.
Contact with live parts at the power connections [X6A], [X9A] and [X9B] can result
in severe injuries or death.
• Do not pull out power supply plugs while live.
• Before touching, wait at least 5 minutes after switching off the load voltage to
allow the intermediate circuit to discharge.
•
Clean the outside of the product with a soft cloth.

Diagnostics via LED
On the front and top of the device, there are some LEDs for indicating status
information. The number of LEDs depends on the product design. Up to 11 LEDs
are located on the front of the device. Up to 4 LEDs are located on the top of the
device at the connections [X19], XF1 IN and XF2 OUT.
The following image shows an example of the LEDs on the front of product variant
CMMT-AS-...-MP.
