Remedy
(1)Check the following settings.
·Check the current capacity of the amplifier before/after replacement by the
model described in board.
·When the external axis is mounted, check if there is no difference between the
amplifier selected at configuration and practically mounted one.
Reference parameter: from SVCxB025
(1)Turn the power OFF then back ON.
(2)If the alarm occurs again, replace controller. Save the CMOS.BIN before
replace controller to be safe.
(1)Turn the power OFF then back ON.
(2)If the alarm occurs again, replace controller. Save the CMOS.BIN before
replace controller to be safe.
(1)Turn the power OFF then back ON.
(2)If the alarm occurs again, replace controller. Save the CMOS.BIN before
replace controller to be safe.
(1)Turn the power OFF then back ON.
(2)If the alarm occurs again, save the CMOS.BIN in maintenance mode, and
then contact your YASKAWA representative about occurrence status (operating
procedure).
(1)Turn the power OFF then back ON.
(2)If the alarm occurs again, replace controller. Save the CMOS.BIN before
replace controller to be safe.
(1)Turn the power OFF then back ON.
(2)If the alarm occurs again, check the connecting or inserting state of the
following cables.
{Robot axis}
·Cables between the controller and the encoder.
{External axis}
·Cables between the controller and the encoder.
(1)Turn the power OFF then back ON.
(2)If the alarm occurs again, replace the encoder.
(1)Turn the power OFF then back ON.
(2)If the alarm occurs again, replace controller. Save the CMOS.BIN before
replace controller to be safe.
