tem configuration is correct, replace
installed motor with correct one. If set
data by system configuration is not cor-
rect, set the correct system configura-
tion.
• If the error occurs again, replace
WRCA01 and/or WRCF01 circuit board.
• Replace the amplifier, motor for axis
where the error occurred.
• Check the connection of UVW wire of
motor again.
<Error in robot axis>
Check that the type of motor is same as
