Cross-wiring
Cross-wiring makes it possible to set up a device compound consisting of up to 10
servo drives CMMT-AS. The different cross-wiring options are as follows:
–
Cross-wiring of I/O signals at the connection [X1A]
–
Cross-wiring of the mains and logic voltage supply without DC link coupling
–
Cross-wiring of the mains and logic voltage supply with DC link coupling

STO installation
Inputs and outputs for the safety sub-function STO
The 2-channel request for the safety sub-function is made via the digital inputs
#STO-A and #STO-B. The STA diagnostic output indicates whether the safe status
has been reached for the safety sub-function STO.

Inputs and outputs for the safety sub-function SBC
The 2-channel request for the safety sub-function is made via the digital inputs
#SBC-A and #SBC-B at the connection [X1A]. The SBA diagnostic output indicates
whether the safe status has been reached for the safety sub-function SBC. The
holding brake is connected via the connection [X6B]. The external clamping unit is
connected via the connection [X1C].

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
protection 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:
–
Functional test
–
Project management
–
Documentation
–

8.2
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 wiring of the CMMT-AS.
2. Install Festo Automation Suite plus CMMT-AS plug-in on the PC.
3. Create project and add CMMT-AS device.
4. Establish connection to the CMMT-AS and set network configuration.
5. Identify the technical data of the components that is required for configura-
tion.
