Cause
• An amount of time after either
the HWTO1 input or the
HWTO2 input is turned OFF
until the other input is turned
OFF exceeded the value set in
the HWTO delay time of
checking dual system (4191h).
• An error of the circuit
corresponding to the
phenomenon above was
detected.
• When the FW-LS/RV-LS input
action (4701h) 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.
The LS input opposite to the
operating direction was
detected while return-to-home
operation in the 2-sensor mode
or the 3-sensor mode was
performed.
• 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 (P-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.
The HOMES input was not
detected at a position between
the FW-LS input and the RV-LS
input while return-to-home
operation in the 3-sensor mode
was performed.
Remedial action
• Increase the value set in the
HWTO delay time of checking
dual system (4191h).
• Check the wiring of the HWTO1
input and the HWTO2 input.
Check the sensor logic installed
and the "Inverting mode"
parameter.
Check the wiring of the sensor.
• 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
Homing acceleration (609Ah).
Install the HOME sensor at a
position between the FW-LS and
RV-LS sensors.
