Explanation of Functions
Input Mode (
cntm
)
Set increment mode (UP) or decrement mode (DOWN) as the input
mode.
Output Mode (
outm
)
Set the way that control output for the present value is output. The
possible settings are N, F, C, R, K-1, P, Q, and A.
One-shot Output Time (
otim
)
Set the one-shot output time (0.01 to 99.99 s) for control output.
One-shot output can be used only when C, R, K-1, P, Q, or A is
selected as the output mode.
Counting Speed (
cnts
)
Set the maximum counting speed (30 Hz/5 kHz) for count inputs.
Reset Input Signal Width (
iflt
)
Set the reset input signal width (20 ms/1 ms) for reset inputs.
If contacts are used for the input signal, set the input signal width to
20 ms. Processing to eliminate chattering is performed for this setting.
Decimal Point Position (
dp
)
Decide the decimal point position for the present value.
Prescale Value (
pscl
)
Pulses input to the counter are converted according to the specified
prescale value.
(Setting range: 0.001 to 99.999 for 6-digit models.)
Example: To display the feed distance for systems that output 25
pulses for a feed length of 0.5 m in the form
@@
.
@@
m:
1. Set the decimal point position to 2 decimal places.
2. Set the prescale value to 0.02 (0.5
÷
25).
• Observe the following points when setting a prescale value.
Set the set value to a value less than {Maximum countable value
−
Prescale value}.
Example: If the prescale value is 1.25 and the counting range is
0.000 to 999.999, set the set value to a value less than 998.749
(= 999.999
−
1.25).
If the set value is set to a value greater than this, output will not turn
ON.
• Output will turn ON, however, if a present value overflow occurs
(FFFFFF).
Set Value Upper Limit (
sl-h
)
Set the upper limit for the set value when it is set in run mode.
The setting can be made from 1 to 999999 for 6-digit models.
Key Protect Level (
kypt
)
Set the key protect level.
Refer to
Key Protect Level
on page 16.
Output ON Count Alarm Set Value (
on-a
)
Set the alarm value for the output ON count.
The limit can be set to between 0
×
1000 (0 times) and 9999
×
1000
(9,999,000 times). Only the underlined values are set. The alarm will
be disabled if 0 is set.
If the total ON count of the output exceeds the alarm set value,
e3
will be displayed on the Timer to indicate that the output ON count
alarm value was exceeded. Refer to
Self-diagnostic Function
on
page 16 for information on the
e3
display.
Output ON Count Monitor Value (
on-c
)
The monitor value is only displayed. It cannot be set.
The output ON count will be 1,000 times the displayed value.
25 pulses
Encoder
0.5 m
Note:
If the prescale value setting is incorrect, a counting error will
occur. Check that the settings are correct before using this
function.
