Rockwell Automation 2LW3000 LonWorks Communication Option Module for VTAC 7 Drives - Manual (Page 48)

6-2 LonWorks Module for VTAC 7 Drives
6.2 Setting the Network Connection Type (P.061)
Parameter P.061 (Network Connection Type) selects the type of network connection.
Setting P.061 = 1 provides full drive control from the network. Any drive data that has
been assigned a network register is transferred over the network. Parameter P.061
must be set to 1 to configure the drive over the network and have access to most
parameters, operating variables, and diagnostic information. The LonWorks module
will fault the drive if P.061 is not set to 1.
6.3 Setting the Communication Loss Response (P.062)
Parameter P.062 (Communication Loss Response) specifies how the drive responds
to a network communication loss when the Control Source (P.000) parameter is set to
OP (Option port).
If the option port is not in control of the drive, but is only monitoring drive operation,
then loss of network communications has no effect on drive operation. In all cases, the
LonWorks module, upon loss of communication with the network, will attempt to
re-establish the communication link.
To eliminate extraneous fault conditions when a drive configured for network operation
is powered up, the drive will delay for approximately 20 seconds after power up before
annunciating a fault condition. A fault condition will be annunciated if network
communication is not established before the 20-second power-up timer expires, or if
network communication was established and then lost.
If the drive loses communication with the network, overspeed protection for the drive
will be in effect under all circumstances. you program overspeed protection in H.022.
When the motor goes above the overspeed limit, the drive faults and stops.
