9-3 Description of input signals
Operation input signals vary depending on the input mode. The input mode can be changed by the setting of the "Operation
input mode selection" parameter (ID: 1819). Refer to p.64 for details.
Operation input signals
2-Wire mode: FWD input, REV input, STOP-MODE input
3-Wire mode: START/STOP input, RUN/BRAKE input, CW/CCW input
2-Wire mode
z
FWD input, REV input
When the FWD input is turned ON, the motor rotates in the forward direction. The motor decelerates to a stop when the signal is
turned OFF.
When the REV input is turned ON, the motor rotates in the reverse direction. The motor decelerates to a stop when the signal is
turned OFF.
The chart below shows an example when the "Motor rotation direction" parameter (ID: 450) is set to “Positive direction=CW.”
If the "Operation input mode selection" parameter (ID: 1819) is set to "2-Wire mode 1,” the motor decelerates to a stop when both
the FWD input and the REV input are turned ON.
z
STOP-MODE input
This is a signal to select how the motor would stop when the FWD input or the REV input is turned OFF.
When the STOP-MODE input is OFF, the motor decelerates to a stop according to the deceleration time of the operation data
number.
When the STOP-MODE input is ON, the motor stops at the shortest time (instantaneous stop).
