Measurement Mode Parameter Setup Mode
At the time of rotational acceleration/deceleration
measurement (when Algorithm E of the ACT mode is
selected), this switch is used to select a rotational
speed at the start of measurement from sampled
candidate values.
Selects the parameter setup mode.
In the measurement mode, at the time of rotational
acceleration/deceleration measurement (when the
"ACT" mode is selected), this switch is used to sample
rotational speed data before starting measurement and
calculate candidate values of the rotational speed at the
start of measurement.
At the time of rotational acceleration/deceleration
measurement (when Algorithm E of the ACT mode is
selected), this switch is used to determine a value selected
by the RECALL & ↑switch as a rotational speed at the start
of measurement, and then starts measurement.
Changes the selection of the current setting. During
numerical parameter setup, increments the numerical
value of the relevant digit. When the value is 9, returns
to 0.
Ends the measurement mode and then turns OFF the power. Cancels the current setting and then turns OFF the power.
Applies the current setting and then changes to the
measurement mode.
During numerical parameter setup, moves the setting
cursor to the right. When the setting cursor is at the least
significant digit, returns to the most significant digit.
Applies the current setting and then moves to the next
setting.
Note: When Algorithm D is selected, the function to select a candidate value of the rotational speed is not provided.
④When you perform measurement for the first time, set each
parameter first.
2.Function of Each Switch

tion between the measurement mode and the parameter setup
mode.
The function of each switch in each mode is shown below.
3.Setup Mode

1. Steady Rotation Measurement Mode "CNS"
This mode is effective when the rotational speed of the object
under measurement is fixed. In this mode, either of the following
two algorithms can be selected according to the object under
measurement in algorithm setup from the setup menu.
① TYPE-A (Algorithm A/Maximum Power Spectrum Peak Detection
Method)
The most basic algorithm suitable for measurement of rated
rotational speed, etc.
② TYPE-B (Algorithm B/Peak-Interval Mode Method)
This algorithm emphases the stability.
However, since this algorithm is inferior to TYPE-A in tracking
performance, measurement may not be performed correctly
if a rapid rotational variation occurs. Further, depending on
the waveform of the sensor signal, measurement may not be
performed correctly.
Because of the measurement principle of algorithms, the
upper limit of the input frequency is about one third of the
frequency range.
Note: When Algorithm B is selected, the filter function is
disabled.
2. Rotational Acceleration/Deceleration Measurement Mode "ACT"
This mode is effective when measuring the rotational speed of
an object under measurement, which is accelerating or deceler-
ating. In this mode, either of the following two algorithms can be
selected according to the object under measurement in algo-
rithm setup from the setup menu.
① TYPE-D (Algorithm D)
This algorithm is suitable for measurement when the rotational
speed accelerates or decelerates.
Performs measurement by changing the measurement time
according to variation of the rotational speed.
② TYPE-E (Algorithm E)
This algorithm maintains a balance between the tracking
performance and the stability of the rotational speed.
Performs measurement focusing on a selected power spectrum.
However, since this algorithm is inferior to TYPE-D in tracking
performance, measurement may not be performed correctly if the
rotational speed changes rapidly.
3. "ACT" Mode Measurement Procedures
Ⅰ: Algorithm: TYPE-D
① When the power is turned ON or the setup mode is terminated,
"rEAdY" is displayed in the MAIN display.
② Set the object under measurement to the rotational speed at the
start of measurement (make the rotational speed as stable as
possible). When measurement is ready, press the "SAMPLE"
switch.
③ Measurement starts.
* Measurement does not start if the rotation signal is not input.
④ To stop (cancel) measurement and then perform measurement
again, press the "SAMPLE" switch during measurement.
⑤ Control returns to step ① . Proceed with step ② .
Ⅱ : Algorithm: TYPE-E
① When the power is turned ON or the setup mode is terminated,
"rEAdY" is displayed in the MAIN display.
② Set the object under measurement to the rotational speed at the
start of measurement (make the rotational speed as stable as
possible). When measurement is ready, press the "SAMPLE"
switch.
③ Candidate values (up to eight values) of the rotational speed at
the start of measurement are displayed.Select a candidate value
that is closest to the current rotational speed using the "RECALL"
switch and then apply it using the "MODE & NEXT" switch.
④ Measurement starts.
⑤ To stop (cancel) measurement and then perform measurement
again, press the "SAMPLE" switch during measurement.
⑥ Control returns to step ① . Proceed with step ② .

Cause of Error
A backed up parameter is not set correctly.
The FT-7100 could not normally be activated.
The amplifier sensitivity for sensor is
excessive.
A detected rotational speed exceeded the
maximum display range, i.e., "99999 r/min."
When the drive mode is the rotational
acceleration/deceleration measurement
mode (when the "ACT" mode is selected),
the rotational speed cannot be measured
correctly (tracked rotational speed is lost).
The rotational speed becomes out of the
range set with the filter.
When the drive mode is the rotational
acceleration/deceleration measurement
mode (when the "ACT" mode is selected),
the rotational speed at the start of mea-
surement cannot correctly be sampled.
With filter settings, the lower-limit setting is
equal to or greater than the upper-limit
setting.

and the fuse may have blown. Contact Ono Sokki sales office.
