2.4 Network management
The NMT services have the following functions:
● Start Remote Node
Command for switching from the "Pre-Operational" communication state to "Operational".
The drive can only transmit and receive process data in the "Operational" state.
● Stop Remote Node:
command for switching from "Pre-Operational" to "Stopped" or from "Operational" to
"Stopped". The node can only process NMT commands in the "Stopped" state.
● Enter Pre-Operational:
command for switching from "Operational" or "Stopped" to "Pre-Operational". In the "Pre-
Operational" state, the node cannot process any PDO. It can, however, be parameterized
or operated via SDOs, which means that setpoints can also be specified.
● 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 their saved values.
● Reset Communication:
command for switching from "Operational", "Pre-Operational", or "Stopped" to
"Initialization". When the "Reset Communication" command is issued, all the
communication objects (1000 hex - 1FFF hex) are reset to their saved values.
CANopen-NMT state
The CANopen NMT state can be displayed or the desired state set using the parameter
p8685.
Possible values:
● 0: Initializing (display only)
● 4: Stopped
● 5: Operational
● 127: Pre-operational
● 128: Reset Node
● 129: Reset Communication
Note
Sending an incorrect NMT state
If the control sends an incorrect NMT state to the inverter, the inverter goes into the
"Stopped" state.
