4.9.11.2 Commissioning
Commissioning
When commissioning via STARTER, parameters are assigned to "external fault 3" and
acknowledged automatically when option L61, L62, L64, or L65 is selected.
When commissioning via AOP30, the parameter entries required have to be set
subsequently.
If, during operation, an "Acknowledge fault" signal is initiated without there being a fault in
the Braking Module, then this initiates an external fault 3.
You can prevent this response with the following measures:
● Link the "Acknowledge fault" signal with status bit 3 "Fault active" of status word ZSW1
(r2139.3).
● If a fault is not active, then do not initiate an "Acknowledge fault" signal.
Cabinet unit settings
If the thermostat for the braking resistor is connected to digital input 11 of the TM 31,
appropriate settings must be made so that the drive is stopped if a fault occurs.
Once the device has been successfully commissioned, you have to make the following
changes:

Connect the "Operation" signal to the second input of "External
fault 3."
Connect "Acknowledge fault" to digital output 15 (DO15) on the
Control Unit.

<Key pushbutton> - <Access level> - Set "Expert" and confirm.
Interconnect external fault 2 to DI 11 of the TM31.
