Note
When the pushbutton is actuated, the locally connected drive systems are brought to a
standstill with no feedback to the control. In other words, the drive and control run
asynchronously once the drive has been successfully powered up.
7.8.2 Mounting
Designs
The NX10.3 is integrated into the SINAMICS drive line-up. For the preferred installation
sequence, the NX module should be mounted at the side of the Line Module.
NOTICE
