Item Applicable Counters Description Setting values
Decimal point H7CR-B, H7CR-SB Determines the position of the Increment keys 1 to 6 move decimal point.
H7CR-C, H7CR-SC decimal point on the display.
H7CR-8, H7CR-11 Press the Increment keys 1 to 6 to
move the decimal from left to right.
Scale factor H7CR-B, H7CR-SB Used to convert counts to other Increment keys 1 to 5 change the scaling
H7CR-C, H7CR-SC units, (e.g., to display millimeters
H7CR-8, H7CR-11 when each input pulse represents
0.02 mm, input a scale factor
of 0.02). Values from 0.001 to 99.999
are possible. Press the Increment
keys to set the desired value.
Key protection H7CR-B, H7CR-SB Blocks certain keys to prevent Increment keys 1 to 4 change key
level H7CR-C, H7CR-SC accidental operation. The key protection level.
H7CR-11 protection level, kP-1 to kP-4,
determines which keys are locked
out when the key protection input
is ON. The locked keys are crossed
out in the diagrams at right.
Note: Settings changed in the Setting mode are effective only after returning to the Run mode.
Changing the Set Value
When changing the set value while the counter is operating, an
output will be produced if the set value ever equals the present
value. To avoid triggering the output, begin by setting a higher
digit to a larger number.
1. Press the DISPLAY key to change the displayed values for
preset 1 and 2 during operation.
The following table shows the delay from when the present
value passes the set value until the output is produced. The
delay is the result of output control time, signal transmission
time, relay switching time etc.
Actual measurements in N and K modes:
Control Max. counting Output
output speed delay*
Contact 30 cps 18 to 24 ms
OUT1, 1 kcps 4.7 to 5.8 ms
OUT2 5 kcps 4.4 to 5.4 ms
Transistor 30 cps 13.5 to 20 ms
OUT1, 1 kcps 0.59 to 0.81 ms
OUT2 5 kcps 0.29 to 0.44 ms
* The variation in delays is due to different modes and
conditions. For systems where the delay is a problem, take
actual measurements under operating conditions.
Output Delay
2. Change the set value from
250 to 1,250.
Pressing increment keys 1
to 6 advances the
corresponding column
value by 1.
Nonsignificant zeros are
not normally shown on the
set value display.
