Set the sequence of each speed
This sequence following three methods.
Select a run/stop operation from the
pattern run mode
 (
Patterned operation canceled during stop
)
Pattern run is reset by stop/switching
operation before operating restarts.
(
Patterned operation continued during stop
)
Pattern run is started by stop/switching
operation. The system stops temporarily on
completion of every routine, then proceeds to
the next routine.
Select a pattern group, and then set the
sequence of each speed

According to the required parameter
group, select pattern group #1, #2, #3 or
#4 from input terminal selection  to
. If you set   at at
item 3 above, select step trigger signals
from  . Selecting pattern
run continuation signals makes it possible
to select a start/stop method.

Monitor displayed during pattern run
During pattern operation, the following run information is displayed before the normal display.
Pattern run switching output (output terminal function : 36, 37)
If the pattern run switching output function is selected (activated), a signal is put out on
completion of all the predetermined patterns of operation. When there is no operation
command left to be entered or the pattern operation selection signal changes, the output
terminals are turned off(in case of a-contact).

(A): Number or the pattern group
(B): Number of the pattern
Number of repetitions 
Means that the current pattern operation is to
be repeated (ex. 123 times).
Preset operation speed 
Frequency reference with preset-speed #1
data.
Remaining time of the
current pattern operation


Current pattern is finished in 1234 seconds.
Operation time is set for infinity or the system
is waiting for the next step command.
