Parameter setting for the Lost Command
According to the decision criteria of the Lost Command of the IS7 CANopen, it judges that the Master and Slave
are connected when the NMT status of the CANopen is Operation, and it does not generate Lost Command. That
is, when the NMT State different from Operation is maintained for longer than the time set up in the PR-13, the
inverter turns to Lost Command state. However, the Lost Command can be generated only when one or more of
the frequency command or operation command is set to Fieldbus.
