ALM-RST input
The ALM-RST input is a signal to reset an alarm status. (The alarm will be reset at the ON edge of the input.)
To reset an alarm, turn the operation input signal OFF, and remove the cause of the alarm before turning the ALM-RST
input ON. In the case of the 3-wire mode, when both the START/STOP input and RUN/BRAKE input are being ON, the
ALM-RST input is disabled. (In the case of the 2-wire mode, when either the FWD input or the REV input is being ON, the
ALM-RST input is disabled.) If an alarm cannot be reset with the ALM-RST input, once turned o the power supply and
turn on again.

*
If an alarm is generated while the motor rotates, the motor will stop. The stopping method varies depending on the alarm
type.
Note
•
Continuing the operation without removing the cause of the alarm may cause damage to equipment.
•
Alarms of overcurrent, EEPROM error, and CPU error cannot be reset with the ALM-RST input.

INFO-CLR input
The INFO-CLR input is a signal to clear an information status. (Information will be cleared at the ON edge of the input.)
This signal is used when the "INFO auto clear" parameter is set to disable. If it is turned from OFF to ON while information
is being generated, the information status will be cleared.

Parameter name Description Setting range Factory setting
INFO auto clear
This is a function to clear the information status automatically when the cause of
the generated information was removed.

HMI input
The HMI input is a signal to release the function limitation of the
MEXE02
.
When the HMI input is turned ON, the function limitation of the
MEXE02
is released.
When the HMI input is turned OFF, the function limitation is imposed.
[Functions to be limited]
•
Writing of operation data and parameters
•
I/O test
•
Teaching/remote operation
•
Clearing of records and others
•
Conguration
•
Initialization (restores to the factory setting)
Even if the function limitation of the
MEXE02
is imposed by the HMI input, it can be released by executing "HMI
release" such as inputting the key code using the
MEXE02
or RS-485 communication.
Note
•
The HMI input is always ON (active state) as an internal signal if it is not assigned to the direct input or the remote
input. When this signal is in an ON state (active state), the function limitation of the
MEXE02
is not imposed (the
HMI input is not assigned at the time of shipment).
•
If the HMI input is assigned to both the direct input and the remote input or to multiple terminals, when all
assigned input terminals are turned ON, it is in an ON state (active state) as an internal signal and the function
limitation is released.
