Note
•
Do not turn off 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 effective. When setting the
speed increasing ratio to other than 1.00, the speed increasing ratio will be effective.
•
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, the "overload alarm detection time except when holding
a shaft" is maximum 5 seconds.

Input
IN0

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 alarm. Refer to p.34 for timing chart.
EXT-ERROR
When turning this signal OFF, an alarm generates and the motor stops instantaneously.
Then "
AL6E
" 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

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 becomes equal the value set by 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.
