*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 1-10s or∞ can be selected
by using user parameter.
Exception: Battery alarm is fixed 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 ∞.
How to Clear the Battery Alarm
Replace the battery for absolute encoder when battery alarm occurs according to P.276,
"How to Replace the Battery". After replacement, clear the battery alarm in the following
3 methods.
(a) "Connector X4" Connecting Alarm clear input (A-CLR) to COM– for more than 120ms.
