44 Speed matching
range
When “ 40 O1 function selection” and “ 41 O2 function selection”
are chosen to
(STABLE) Arriving signal, “Speed
matching range" for output arriving signal can be adjusted.
• When difference between actual rotation speed and speed
setting is smaller than "Speed matching range”, arriving signal
is output.
• Even if the speed is reached, when speed matching range is
set too small, arriving signal may turn on and off due to speed
fluctuation.
• Arriving signal is not output when CCW/CW changes.
45 Output pulse count
selection
When “ 40 O1 function selection” and “ 41 O2 function selection”
are set to
(PULSE-OUT), pulse count is set to be output
to “O1” “O2” while the motor makes one turn.
(To be selected from 1, 2, 3, 4, 6, 8, 12, and 24)
• Select 12 or less, When you need exceeding 3000 r/min.
500±100 μs
(Ex) When rotation number is 3000 r/min,
in the case where “
45

selection” is 24,
Frequency f = 1/T = 1.2 kHz

Rotation angle of a motor is divided into the number set up by
Pr45, and a pulse is outputted at the division position. By using
an analog filter, it is a signal for checking a near speed in analog
meter etc. Since there are no hysteresis characteristics, and there
is possibility of the incorrect detection by disturbance or motor
vibration, please do not use it for position detection.
46 Monitor mode
selection
You can choose description to be displayed on 5-digit LED when
turning on power.
(OUTPUT-REVOLUTION) : Rotation speed
(OUTPUT-LOAD) : Torque reference
(AVERAGE-LOAD) : Load factor
(average of torque reference)
(SETTING-REVOLUTION) : Speed command
(DC-VOLTAGE)
: Internal DC voltage
(Voltage of smoothing capacitor
of power supply)
In speed display mode, the value multiplied by “ 47 Numerator
of display magnification factor” / “ 48 Denominator of display
magnification factor” is displayed.

Description
47 Numerator of display
magnification factor
You can set the multiplying factor of a value displayed on 5-digit
LED. Value of 47 ÷ 48 is a display multiplying factor. Set a value
in the range where calculated display magnifying factor is 10
to 1/1000. Rotation number of gear output shaft and the speed
of line can be displayed. When the display magnifying factor is
changed, the parameter relating to speed (below) is displayed by
a value multiplied by display multiplying factor. “ 00 Internal speed
(0-th speed)” “ 01 1st speed” “ 3A Lower speed limit” “ 3b Upper
speed limit” “ 44 Speed matching range”

4A Trip history clear
Trip history 1 to 5 can be cleared.
<Clear procedure>
Cut off power with
(YES) selection, and turn on power
again after display has disappeared, then
is displayed,
and trip history is cleared. When power is turned on again, normal
operation is started.
(Caution) It can not be cleared during RUN command input.

Trip history for 5 times in the past is stored. Trip history 1 is the
latest history. See “Protective function” for displayed description.
When no history is available,

50 Undervoltage trip
selection
When
(NO) is selection, the motor is not tripped at
insufficient voltage. If voltage should fall and undervoltage status
is found while the motor is running, the motor stops after running
free, while if operation instruction is input after recovery of power,
the motor is restarted automatically. (• Be cautious.)
When
(YES) is selection, the motor is tripped at
undervoltage, and alarm LED blinks. When normal power is off,
trip is not stored in trip history. Trip is stored only when power has
stopped instantaneously (Trip is stored in trip history only when
undervoltage once becomes short and then is recovered normal)
