Operating Instructions, 01/2011, FW 4.4, A5E02430659B AD
The NMT recognizes the following transitional states:
●
Start Remote Node:
command for switching from the "Pre-Operational" communication status to
"Operational". The drive can only transmit and receive process data (PDO) in
"Operational" status.
●
Stop Remote Node
command for switching from "Pre-Operational" or "Operational" to "Stopped". The node
can only process NMT commands in the "Stopped" status.
●
Enter Pre-Operational
command for switching from "Operational" or "Stopped" to "Pre-Operational". In this state,
the node cannot process any process data (PDO). It can, however, be parameterized or
operated via SDOs, which means that you can also enter setpoints via SDO.
●
Reset Node:
command for switching from "Operational", "Pre-Operational", or "Stopped" to
"Initialization". When the Reset Node command is issued, all the objects (1000 hex -
9FFF hex) are reset to the status that was present after "Power On".
●
Reset Communication:
command for switching from "Operational", "Pre-Operational", or "Stopped" to
"Initialization". When the Reset Communication command is issued, all communication
objects (1000 hex - 1FFF hex) are reset to the status that was present after "Power On".
