Information of the connected the YSU unit failure
EAXA board is different between
the CPU1 and the CPU2 of the
YSU unit.
Remedy
Check if the primary power supply voltage is dropping.
Check if the instant power failure has occurred.
Check if the primary power supply voltage is dropping.
Check if the instant power failure has occurred.
Check the settings for manipulator motion condition (influence by external
force, load condition).
Remove interference of the manipulator.
Check the connection of motor power line.
(1)Reset the alarm.(In case of major alarm, turn the power OFF then back
ON.)
(2)If the alarm occurs again, replace the EAXA board. Save the CMOS.BIN
before replace the board to be safe.
