First commissioning of the PLC completed
To synchronize the PLC and NC, an NC reset (po) is required.
The PLC and NC are in the following state after a reset (po):
● RUN LED is continuously lit green.
● Status display shows a "6" with a flashing dot.
⇒ PLC and NC are in cyclic operation.
You have completed the first commissioning of the PLC.
Continue with the steps for "Guided commissioning (Page 113)" of the SINAMICS drives.
You start with a reset (po) for the NC and drive system.
Note
Response of the PLC in the case of an NC stop
For a stop of the NC, the PLC normally continues to run and the type of stop response is the
user's responsibility depending on the machine situation. In this special case, the NC can no
longer switch the outputs to zero and the current status is retained because the PLC is still
running.
In order to switch off the outputs or to force a PLC stop, for example, the "NC READY" signal
is evaluated in the PLC program.
