Tachometer
NPN/PNP Input Mode (
imod
)
★
Select either NPN input (no-voltage input) or PNP input (voltage
input) as the input format.
When using a two-wire sensor, select NPN input. The same setting is
used for all external inputs.
For details on input connections, refer to Input Connections on page
page 9.
Display Color (
colr
)
Set the color used for the measurement value.
*1. If the tachometer output mode is set to AREA, however, the measured
value is displayed in red when control output 1 is OFF and in green when
control output 1 is ON.
*2. If the tachometer output mode is set to AREA, however, the measured
value is displayed in green when control output 1 is OFF and in red when
control output 1 is ON.
*3. If the tachometer output mode is set to AREA, however, the measured
value is displayed in red when control output 1 is OFF and in orange when
control output 1 is ON.
*4. If the tachometer output mode is set to AREA, however, the measured
value is displayed in orange when control output 1 is OFF and in red when
control output 1 is ON.
*5. If the tachometer output mode is set to AREA, however, the measured
value is displayed in green when control output 1 is OFF and in orange
when control output 1 is ON.
*6. If the tachometer output mode is set to AREA, however, the measured
value is displayed in orange when control output 1 is OFF and in green
when control output 1 is ON.
Peak/bottom Hold Enabled (
dhld
)
This function records the peak and bottom (i.e., minimum) after
counting starts (after turning ON the power supply or changing the
configuration selection mode or function setting). The peak value is
also held when the power supply is interrupted.
Output Hysteresis (
hys
)
This setting can be used to prevent output chattering if the
measurement value fluctuates slightly near the set value.
The measurement value after prescaling is set.
Output OFF Delay (
offd
)
This function delays the timing for turning OFF comparative output by
a certain time.
The ON time can be held for the set time if the comparative result
changes in a short time.
Operation will continue and outputs will not change when holding the
value.
Set Value Upper Limit (
pl-h
)
Set the upper limit for the set value when it is set in run mode. The
limit can be set to between 1 and 999999.
Output Allocation (
otst
)
When using an H7CX-AU
@
-N model as 2-stage counter, each output
can be flexibly allocated to either stage 1 or 2.
The transistor output can be allocated to SV1 and the contact output
to SV2 or vice verse, as in the following tables.

Key Protect Level (
kypt
)
Set the key protect level.
Refer to Key Protect Level on page page 36.
Pulse Cycle Measurement/Pulse Width Measurement
(
calm
)
Set the measurement mode to pulse cycle measurement or pulse
width measurement.
With pulse cycle measurement, the number of pulse cycles that occur
in 1 s is measured.
With pulse width measurement, the ON time for one pulse is
measured.
An input OFF period of at least 20 ms is required for pulse width
measurement.
If there is no input pulse during pulse width measurement, the
previously measured value will be held.
Display Unit (
unit
)
When pulse cycle measurement is used, set the display unit to Hz
(hertz) or s (seconds).
Counting Interval (
intv
)
If the measurement speed is 10 kHz when pulse cycle measurement
is used, set the measurement interval to 200 ms or Cont (10 ms min.).
