Overload alarm detection time
except when holding a shaft
Sets the time to output the alarm after
detecting the overload condition when
a load up to the limited duty region
exceeding the continuous duty region
was applied.
0.1 to 60.0 s 30.0
Overload warning level
Sets the detection level (load factor) for
the overload warning function based on
the rated current being 100%.
50 to 120% 120
Rotation speed attainment band
Sets the band within which the rotation
speed of the motor is deemed to have
reached the set value.
0 to 400 r/min 200
Initialize the parameter mode
Restores the value set in the parameter
mode to the factory setting.

Note
•
Do not turn o the motor power while the initialization is still in progress (= while the display is blinking).
Doing so may damage the data.
•
When setting the speed increasing ratio to 1.00, the speed reduction ratio will be eective. When setting the speed
increasing ratio to other than 1.00, the speed increasing ratio will be eective.
•
When setting a longer time in the "overload alarm detection time except when holding a shaft" parameter, an
overload status may continue. Repeating this condition may result in shorter service life of the motor and gearhead.
•
If a load exceeding the limited duty region was applied or the output shaft was locked, the "overload alarm
detection time except when holding a shaft" is maximum 5 seconds.
Description of I/O signals
Signal Terminal Signal name Description
Input
IN0
IN1
IN2
IN3
IN4
FWD The motor rotates when either of the FWD input or REV input is turned ON. If
the FWD input and REV input are turned ON simultaneously, the motor stops
instantaneously.
REV
M0
These signals are used to select the operation data number.
If both signals are turned OFF, the operation data No.0 is selected.
M1
ALARM-RESET
This signal is used to reset the present alarm when a protective function was
activated. Refer to p.36 for timing chart.
EXT-ERROR
When turning this signal OFF, an alarm generates and the motor stops
instantaneously. Then "
" will be shown on the display (normally closed).
H-FREE
The slight position-keeping is released when the H-FREE input is turned ON.
(When the slight position-keeping selection is set to "Enable")
Output
OUT0
OUT1
ALARM-OUT1 This signal is output when an alarm generates (normally closed).
SPEED-OUT
30 pulses are output with each revolution of the motor output shaft synchronously
with the motor operation. The pulse width of output pulse signals is 0.2 ms. You can
use the SPEED-OUT output to calculate the motor speed.
Rotation speed (r/min)
60
SPEED-OUT output frequency
D-OUT output frequency (Hz) =
T
0.2 ms
ALARM-OUT2
This signal is output when exceeding the overload warning level.
Or this signal is output when an overload alarm generates (normally closed).
MOVE This signal is output while the motor is operating.
VA
This signal is output when the motor rotation speed reaches "plus or minus range of
rotation speed attainment band against the setting speed."
A range to turn the VA output ON can be set using the "rotation speed attainment
band" parameter.
WNG
This signal is output when a warning generates. (The motor will continue to operate.)
When the warning is released, it will automatically turn OFF.
Note
Do not assign the same input signal to multiple input terminals. When the same input signal is assigned to
multiple input terminals, the function will be executed if any of the terminals becomes active.
