I/O signals
10.4 Input signals
This section explains each input signal.
Note
When input signals are assigned to the direct input, in order to surely recognize the input signal, ensure the ON time
and OFF time of each input signal for at least 2 ms.
Names and functions of the operation input signals vary depending on the setting of the "Operation input mode
selection" parameter.
Operation input signals
3-Wire mode: START/STOP input, RUN/BRAKE input, FWD/REV input
2-Wire mode: FWD input, REV input, STOP-MODE input
[3-Wire mode]

START/STOP input, RUN/BRAKE input
The motor rotates according to the acceleration time when both the START/STOP input and the RUN/BRAKE input are
turned ON.
If the START/STOP input is turned OFF while the motor rotates, the motor decelerates to a stop
*
according to the
deceleration time.
If the RUN/BRAKE input is turned OFF while the motor rotates, the motor stops at the shortest time (instantaneous stop).
*
Operation of deceleration stop can be changed by setting of the "Deceleration mode selection" parameter. (p.39)
Note
•
When the START/STOP input and the RUN/BRAKE input are turned OFF simultaneously, the RUN/BRAKE input is
prioritized.
•
The actual acceleration time and deceleration time are aected by customer's conditions of use, load inertia, and
load torque.

FWD/REV input
This is a signal to change the motor rotation direction.
The motor rotates in the forward direction when this signal is turned ON, and in the reverse direction when it is turned
OFF.
The rotation direction of the motor varies depending on the setting of the "Motor rotation direction" parameter or
the gear ratio of the gearhead.
Example:
When the "Motor rotation direction" parameter is set to "positive direction (+) = CW" (factory setting)
