Auto-zero Time (
auto0
)
It is possible to make the settings so that the frequency will be force-
set to 0 if there is no pulse for a specified period of time. This time is
called the auto-zero time.
Startup Time (
stmr
)
In order to prevent undesired output resulting from unstable input
immediately after the power supply is turned ON, measurement can
be prohibited for a set time at startup.
It can also be used to stop measurement and disable output until the
rotating body reaches the normal rate of rotation, after the power
supply to the H7CC and rotating body are turned ON at the same
time.
Peak/bottom Hold Enabled (
dhld
)
This function records the peak and bottom (i.e., minimum) values
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.
In Thachometer Mode, 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 while holding the
value.
Set Value Upper Limit (
sl-h
)
Set the upper limit for the set value when it is set in run mode.
Key Protect Level (
ypt
)
Set the key protect level.
Refer to
Key Protect Level
on page 56.
Output ON Count Alarm Set Value (
on-a
,
on1a
,
on2a
)
The output ON count for notifying the replacement time can be set.
For details, refer to page 57.
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.
ON Count Monitor Values for Outputs 1 and 2 (OUT1 and
OUT2) (
on1c
and
on2c
)
The monitor value for output 1 and 2 (OUT1 and OUT2) is only
displayed. It cannot be set.
The output ON count will be 1,000 times the displayed value.
Output Allocation (
otst
)
Set the allocation of outputs 1 and 2 (OUT1 and OUT2). If output
allocation is OFF, output 1 (OUT1) is allocated to terminals (8), (9),
and (11), and output 2 (OUT2) is allocated to terminals (4) and (7). If
output allocation is ON, output 1 (OUT1) is allocated to terminals (4)
and (7), and output 2 (OUT2) is allocated to terminals (8), (9), and
(11).
Output inversion (
ot-i
,
ot1i
,
ot2i
)
Set logical inversion of output ON/OFF. In the case of two outputs, it
is possible to individually set output inversion for each of output 1 and
output 2 (OUT1 and OUT2). If output inversion is
n-o
(Normally
Open), the output turns ON when the set value is reached. If output
inversion is
n-c
(Normally close), the output turns OFF when the set
value is reached.
Note:
Set the auto-zero time to a time slightly longer than the
estimated interval between input pulses. It will not be
possible to make accurate measurements if the auto-zero
time is set to a time shorter than the input pulse cycle.
Setting a time that is too long may also result in problems,
such as a time-lag between rotation stopping and the
alarm turning ON.
