Meaning
• Turn ON if an error occurs as a result of diagnosis.
• Remains ON even if the condition is restored to normal
thereafter.
• Turn ON by ON to OFF of the Motion error detection flag
(M2039) for except the stop error after confirming the error
content.
• Turn ON if an error occurs as a result of self-diagnosis.
• Remains ON even if the condition is restored to normal
thereafter.
• Turn ON by ON to OFF of the Motion error detection flag
(M2039) for except the stop error after confirming the error
content.
• Turn ON if the voltage of external battery reduces to less than
2.5[V].
• Remains ON even if the condition is restored to normal
thereafter.
• Turn on when the voltage of the external battery reduces to
less than 2.5[V].
• Turn OFF when the voltage of external battery returns to
normal.
• Turn ON if an instantaneous power failure of within 20[ms]
occurs during use of the AC power supply module.
not detected
