Chapter 12 Absolute System
Battery Life
The above figure comes from EVE
(1) The above figure illustrates the discharge current curve generated by constant current test.
According to the testing result shown on the graph above, when the power consumption of an
absolute encoder is 190 uA or lower, if the voltage of the battery keeps 3V or higher, the
expected battery life is about 19.7 months
an absolute encoder is set to 3.1V.
(2) The battery life expectancy is about 5 years and is able to provide 3.6V or higher voltage under
normal temperature and humidity conditions.
Note: the battery life was measured when one single battery box is connecting to one servo drive and one
servo motor.
