7.4.3. Node Guarding
When the Node Guarding message is received, the drive sends the Node Guarding message with the node
state.
When the drive does not receive the Node Guard message in the interval time (=Guard Time x Time Factor,
Max time is limited internally 1 hour.) set by Object 0x100C (Guard Time) and 0x100D (Time Factor), the
drive detects the network error and changes the drive condition according to the parameter setting (c100 ~
c103). If Heartbeat function is used, Node Guarding function doesn’t work.
Node Guarding send data

NMT Boot-up message, should change the drive node state and send appropriate command data.
