"How to Replace the Battery". After replacement, clear the battery alarm in the following
3 methods.

A2 Battery alarm Battery voltage is 3.2 V or lower. Fixed at ∞
A3 Fan alarm Fan has stopped for 1 sec. 1 s to 10 s or ∞

AC Deterioration diagnosis warning
Load characteristic estimates and torque command under
constant speed has exceeded the set range.
1 s to 10 s or ∞
C3 Main power off warning
In case that Pr7.14 (Detection time of main power off warning)
is 10 to 1999, the mains power between L1 and L3 has stopped
instantaneously for more than the time prescribed in Pr7.14.
1 s to 10 s or ∞
*1 Alarms can be cleared by using the alarm clear. Because the all existing alarms are kept cleared while the
alarm clear input (A-CLR) is kept ON, be sure to turn it OFF during normal operation. Either 1 s-10 s or
∞
can be
selected by using user parameter.
Exception: Battery alarm is xed at ∞ because it is latched by the encoder.
Because the end of life alarm means that the life expectancy cannot be extended, the alarm is set at ∞.
