1) This turns ON when the absolute battery voltage is in normal condition or the actuator is in
incremental encoder type.
2) It turns ON once the absolute battery voltage gets to 3.1V or less.
3) An alarm (Code 0EE: Absolute Encoder Error Detection 2) will be generated once the
absolute battery voltage gets to 2.5V or less and the backup data cannot be retained.
4) It turns ON if the motor temperature exceeds the value of this parameter when the overload
caution load level ratio is set to a number other than 100% in Parameter No. 143. Lower the
load level (by decreasing the acceleration speed level, etc.).
Warning: Making an operation with the backup data being lost may cause such
accidents as an injury or malfunction of the actuator body, work piece or the
whole system.
Replace the battery immediately if BALM is turned ON. [Refer to Section 6
Absolute Reset and Absolute battery] Use the dedicated battery (AB-5) for
replacement.

Anti-vibration function controls the vibration of the load caused by IAI actuators.
Measure the frequency and set it to the parameter set. (3 types at maximum)
Select a registered parameter set with the combination of these signals.
