NETW BAUD RATE (P.912)
Sets the baud rate for the DeviceNet Network Communication board. The baud rate for the AutoMax
Network Communication board is not adjustable. Entering a value of 0.0 Kbaud will disable DeviceNet
network communication.
If the AutoMax Network Communication board is being used, this parameter has no effect.
Parameter Range: 0.0 Kbaud
125.0 Kbaud
250.0 Kbaud
500.0 Kbaud
Default Setting: 0.0 Kbaud
Parameter Type: Configurable
NETW COMM LOSS SELECT (P.901)
Network communication loss selection. Selects how the drive will respond to
a loss of network communication when CONTROL SOURCE SELECT is set to NETWORK.
Parameter Range: FAULT,
HOLD LAST REF,
USE TRMBLK REF
Default Setting: FAULT
Parameter Type: Tuneable
OIM Menu Path(s): Network Communications
When NETW COMM LOSS SELECT is set to FAULT, a fault will be generated when network
communication is lost, causing the drive to coast/DB stop. When NETW COMM LOSS SELECT is set to
HOLD LAST REF, the drive will continue to run using the last reference value received over the network.
When NETW COMM LOSS SELECT is set to USE TRMBLK REF, the drive will continue to run using
the selected auto reference value from the regulator board terminal strip. In this configuration, the drive
will automatically switch back to the network reference once network communication is re-established. If
CONTROL SOURCE SELECT is not set to NETWORK, the loss of network communication will have no
effect on the operation of the drive.
DANGER
The user must provide an external operator accessible coast/stop pushbutton at terminals 7 and 8 on
the regulator board (see figure 3.12) to disable the machine in case of improper operation.
Uncontrolled machine operation might result if this is not done. Failure to observe this precaution
could result in severe bodily injury or loss of life.
NOTE: Setting NETW COMM LOSS SELECT to HOLD LAST REF or USE TRMBLK REF will cause an
alarm to be generated when network communication is lost. Since alarms do not cause the drive to stop,
some form of hardwired stop must be available since stopping the drive via the network may not always
be possible. Once the drive is stopped, it cannot be restarted until network communication is re-
established or CONTROL SOURCE SELECT is changed to something other than NETWORK.
