Panasonic MINAS A6 Multi Series - 7.3 Warning Function

Protective Functions
7-32
7.3 Warning function
 The warning will be triggered before the protective function is activated, and you can check the conditions
such as overload beforehand.
 One of the following warning modes can be selected through the setting of Pr 6.27 Warning latch state
setting: the warning non-latch mode in which the warning is automatically cleared 1 sec. after the cause of
warning is removed, and the warning latch mode in which the warning is kept issued even after the cause of
warning is removed. To clear the latched state, use the alarm clearing procedure described in previous alarm
section.
 Note that the battery warning is latched by the encoder: after unlatching at the encoder, the warning is
cleared.
