Rockwell Automation Flex/WebPak 3000 DC Drive ControlNet, Network Communication Board, 915FK2101 - Manual (Page 18)

3-2 ControNet Network Communication Option Board For Use With FlexPak 3000 and WebPak 3000 DC Drives
3.3 Setting CNI PROG/RUN MODE (P.915)
CNI PROG / RUN MODE (P.915) selects how the drive will respond when communicating
with a PLC that is put into program mode while CONTROL SOURCE SELECT (P.000) is set
to NETWORK . When the PLC is put into program mode, alarm A00006 ( CNI PROGRAM
MODE ), is generated to indicate the change in operation of the drive. An alarm is not
generated when the PLC is returned to run mode, since that is considered normal
operation.
When CNI PROG / RUN MODE = STOP (1), the drive will coast/DB stop when the PLC is put
into program mode. The drive can be started only when the PLC is in run mode.
When CNI PROG / RUN MODE = USE LAST REF (2), the drive will not stop (if running) or
start (if stopped) when the PLC is put into program mode. The drive will continue to
use the last network reference received as its speed reference. This will continue until
the PLC is returned to run mode and a new reference value is received.
When CNI PROG / RUN MODE = USE TRMBLK CNTL (3), the drive will not stop (if running) or
start (if stopped) when the PLC is put into program mode (or returned to run mode).
The drive's terminal block will become the source for all control (run, jog, stop, fault
reset, direction and OCL enable) and speed (auto) reference signals.
For FlexPak 3000 drives, the Speed Loop PI Reset and Underwind/Overwind bits
cannot be changed while operating in this mode. They will remain at the last values
received from the network. This will continue until the PLC is returned to run mode
when control/reference will come from the network again.
Range: STOP (1), USE LAST REF (2), USE TRMBLK CNTL (3)
Type: Non-volatile, Configuration
Default: STOP (1)
3.4 Setting NETW COMM LOSS SELECT (P.901)
(FlexPak 3000 Drives Only)
NETW COMM LOSS SELECT (P.901) is not used in WebPak 3000 drives. For WebPak 3000
drives, a fault is generated when network communication is lost if CONTROL SOURCE
SELECT (P.000) is set to NETWORK . This causes the drive to coast/DB stop. The drive
cannot be restarted until the fault is cleared.
!
ATTENTION: CNI PROG / RUN MODE (P.915) allows you to configure the
drive to continue to run when the PLC is put into program mode. You
must provide some form of hardwired stop in case of communication
loss, since stopping the drive through the network might not be possible.
Failure to observe this precaution could result in bodily injury or damage
to, or destruction of, equipment.
