Input signals
The signal state represents "ON: Carrying current state" or "OFF: Not carrying current state" of the internal
photocoupler rather than the voltage level of the signal.
•
FWD input and REV input
When the FWD input is turned ON, the motor rotates in the clockwise direction according to the time set with the
acceleration/deceleration time potentiometer. The motor stops when the signal is turned OFF.
When the REV input is turned ON, the motor rotates in the counterclockwise direction according to the time set with
the acceleration/deceleration time potentiometer. The motor stops when the signal is turned OFF.
If both the FWD input and REV input are turned ON, the motor stops instantaneously.
The rotation direction of the motor can be changed using the "Motor rotation direction selection" parameter of the
MEXE02
or
OPX-2A
.

•
STOP-MODE input
This signal is used to select how the motor should stop when the FWD input or REV input is turned OFF.
When the STOP-MODE input is ON, the motor stops according to the time set with the acceleration/deceleration time
potentiometer.
When the STOP-MODE input is OFF, the motor stops instantaneously.
Note
When the electromagnetic brake type motor is used in vertical drive such as elevating equipment, be sure
to turn the STOP-MODE input ON before stopping the motor. Stopping the motor while the STOP-MODE
input remains OFF may cause the moving part to fall.
•
M0 input
This signal is used to select how the motor speed is set.
When the M0 input is ON, the motor rotates at the speed set with the external potentiometer or external DC voltage.
When the M0 input is OFF, the motor rotates at the speed set with the internal potentiometer.
By switching the M0 input, the motor can be operated at two speeds through use of both the external potentiometer
and internal potentiometer.
Refer to p.35 for details.
Up to eight speeds can be set by assigning the M0 to M2 inputs using the
MEXE02
or
OPX-2A
.
•
ALARM-RESET input
This signal is used to reset the present alarm that the protective function of the driver was activated. Be sure to
remove the cause of the alarm before turning the ALARM-RESET input ON.
To reset an alarm, turn both the FWD input and REV input OFF, and remove the cause of the alarm before turning the
ALARM-RESET input ON (keep it ON for 10 ms or more) and then OFF. The ALARM-RESET input is disabled while the
FWD input or REV input is being ON.
If the alarm cannot be reset with the ALARM-RESET input, turn o the main power supply and turn on it again. If the
control power supply is used, also turn on the control power supply again.

The electromagnetic brake holds the position at the same time when an alarm is generated. If the
MEXE02
or
OPX-2A
is used,
the electromagnetic brake can be set to hold the position after the motor coasts to a stop.
Note
•
Continuing the operation without removing the cause of the alarm may result in damage to equipment.
•
Alarms of overcurrent, EEPROM error, and communication switch setting error cannot be reset with the
ALARM-RESET input.
