List of absolute-encoder backup functions
Battery model
AB-5 (by IAI)
Battery voltage 3.6 V
Current capacity 2000 mAH
Detection voltage for battery
voltage low alarm
(Typical) 3.1 V, 3.0 V to 3.2 V
Detection voltage for battery
voltage low error
(Typical) 2.5 V, 2.3 V to 2.7 V
Time after alarm detection until
error detection (reference)
10 days if the controller is operated continuously at 20
C, or 7 days if no
power is supplied
10 days if the controller is operated continuously at 40
C, or 2.5 days if no
power is supplied
Minimum data retention voltage 2.7 V min. (Varies depending on the encoder characteristics.)
Time after alarm detection until
data loss (reference) With an absolute encoder, absolute reset must always be performed once an
error has been detected.
Data assurance limit during
battery replacement
15 minutes (Maximum time during
which data can be retained without
any battery in the battery holder)
Data is retained by the super
capacitor in the absolute brake unit.
