•
When the “FW-LS/RV-LS input
action” parameter is set to “2:
Immediate stop with alarm”
or “3: Deceleration stop with
alarm,” both the FW-LS input
and the RV-LS input were
detected.
•
Return-to-home operation
was executed in a state where
both the FW-LS input and the
RV-LS input were detected.
Check the sensor logic installed
and the “Inverting mode”

Return-to-home
operation error
•
An unanticipated load was
applied while return-to-home
operation was performed.
•
The installation positions of
the FW-LS and RV-LS sensors
and the HOME sensor are
near to each other.
•
Position preset processing
upon completion of return-
to-home operation was failed.
•
In return-to-home operation
in the one-way rotation
mode, the HOME sensor was
exceeded while the motor
decelerated to a stop.
•
Check the load.
•
Reconsider the sensor
installation positions and the
starting direction of motor
operation.
•
See that a load exceeding the
maximum torque is not applied
upon completion of return-to-
home operation.
•
Reconsider the specifications of
the HOME sensor and the
"(HOME) Acceleration/
deceleration” parameter.

No HOMES
The HOMES input was not
detected at a position between
the FW-LS input and the RV-LS
input while return-to-home

was performed.
Install the HOME sensor at a
position between the FW-LS and
RV-LS sensors.
