These parameters are available only if the ControlNet Network Communication board
is installed. For more informatoin on this board and parameters, see the ControlNet
Network Communication board manual (D2-3425).
CNI PROGRAM RUN MODE
(P.915)
Selects how the drive
responds when
communicating with a
PLC and the PLC is
switched from run to
program mode.
Parameter Range:
1 =
STOP
2 =
USE LAST REF
3 =
USE TRMBLK CNTL
Default Setting:
1 =
STOP
Parameter Type:
Configurable
OIM Menu Path(s):
Network Communications
When the PLC is put into Program mode, alarm A00006,
CONTROLNET 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.
1 (
STOP
): The drive will coast/DB stop (if running) when the PLC is put into Program
mode. When the PLC is in Program mode, the drive cannot be started while under
Network control.
2 (
USE LAST REF
): 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 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.
3 (
USE TRMBLK CNTL
): 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. 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.
!
ATTENTION:
When
USE TRMBLK CNTL
is selected, motor speed and
direction changes can occur when the PLC is changed between Program
and Run modes. All terminal block reference and control signals must
be set to correct values for your application. Failure to observe this
precaution could result in damage to, or destruction of, equipment.
