8.11 Cross-wiring
Cross­wiring makes it possible to set up a device compound consisting of up to 10
servo drives CMMT­AS. The different cross­wiring options are as follows:
–
Cross­wiring of I/O signals at the connection [X1A]
– Cross­wiring of the mains and logic voltage supply without intermediate cir­
cuit coupling
– Cross­wiring of the mains and logic voltage supply with intermediate circuit
coupling

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

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

8.14 SS1 installation
Inputs and outputs for the safety sub-function SS1
The safety sub­function SS1 is wired like the safety sub­function STO but is sup­
plemented by the functional input CTRL­EN so that the braking ramp can be activ­
ated by the safety relay unit.

9 Commissioning
9.1 Safety
WARNING!
Risk of injury from electric shock in case of incomplete insulation at the power
connections [X6A], [X9A] and [X9B].
Before operating, plugging in or unplugging the display and operating unit CDSB
or a connector from a hot­plug­capable interface, the following points must be ful­
filled:
•
The conducting lines at the device are completely insulated.
• The protective earth (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 actu-
ator 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.
Use of safety functions
NOTICE!
The safety sub­functions STO and SBC are already available on the CMMT­AS on
delivery without the need for any additional parameterisation. Prior to initial com­
missioning, you must – as a minimum – wire safety sub­functions 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 13849­1 chapter G.4:
–
Functional test
– Project management
