Reference data retention time after power is cut off
4 levels of 5, 10, 15 and 20 days
Notes: (1) If vibration, shock or other external force is applied to the actuator or the slider or other part
is moved while the power is cut off, the absolute data may be lost.
If the RDY/ALM LED illuminates in green or STATUS1 LED illuminates in red on the front
panel the next time the power is turned on, an absolute encoder error is present. In this
case, you must reset the alarm and perform home return.
Do not move the slider or rod while the power is cut off.
(2) Since the surrounding air temperature during charge affects the charge efficiency, it is
recommended that the controller be used at normal temperature (+10 to +30
C).
If the temperature exceeds 45
C, not only the charge efficiency will drop and the battery
will not be charged sufficiently, but the controller performance may also drop or battery fluid
may leak out.
