H7CC-R

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.
