Applications of Operating Modes

SINGLE OPERATING MODES

Single operating modes are basic modes, among which, Mode
N is the most basic (input the RESET signal to restart).
Mode N
The displayed count-up value is on hold.
Example: Cutting Objects to Specified Size
The object is advanced for a specified distance measured by
encoder pulses to determine correct length for cutting.
Rotary
encoder
Mode A
Select Mode A for a one-shot output of the count-up signal
used in Mode N. The displayed count-up value is on hold.
Mode A can be used for a start signal for sequence control
equipment.
Mode F
Go to Mode F to monitor the number of overrun objects. The
process value is displayed normally. It is possible to monitor
the number of overrun objects upon interruption of the
operation after a specified number of objects are counted.
Mode K
Select Mode K for the one-shot output of the count-up signal
used in Mode F. Mode K can be used as a start signal for
sequence control equipment.

REPETITIVE OPERATING MODES

Modes R and C are typical of repetitive operating modes (the
counter internally resets itself after each counting operation and
then restarts). The counter begins the next counting operation
after the present output is processed.
Mode R
The displayed count-up value is on hold.
Example: Portion Control of Material or Ingredients
The valve is closed when the supplied quantity of cookie batter
or blended ingredient has reached a specified amount.

closing
Mode Q
Choose Mode Q to view the process value continuously. There
is no difference in operation between Mode R and Mode Q.
Mode C
The counting operation restarts upon counting up. The process
value is displayed continuously.
Example: Marking Material at Regular Intervals
A roll of film being advanced is marked at regular intervals
based on encoder input.
Mode P
Choose Mode P to put the count-up value on hold (display is on
hold while the one-shot output is ON). There is no difference in
operation between Mode C and Mode P.
