Connection
4.2 Connecting the Braking Module
Recommended connection for terminal strip X21
The signals of terminal strip X21 can be freely used corresponding to the line-side
requirements.
In connection with the system components used and the default settings of the command
sources during commissioning, the following recommendations for the wiring of the signals
apply.
● X21:2 to CU X132:14 (mass)
● X21:3 on CU X132:9 (DO12 = acknowledge fault)
● X21:5 on CU X132:1 (DI4 = external fault 3)
● X21:6 on CU X132:13 (DO15 = P24V)

configuration
p2108 Ext. fault_3
p3111 BI: External fault 3 enable
p0728.12 Sets CU input or output:
DI/DO 12 (X132.9)
p0742 BI: CU signal source for terminal
DI/DO 12 (X132.9)
Note
Fault acknowledged with r2138.7 for the recommended wiring
If, during operation, an "Acknowledge fault" signal is initiated via terminal X21.3 in the
braking chopper, without there being a fault in the Braking Module, then this initiates an
external fault 3.
You can prevent this response by applying 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.
