12. ABSOLUTE POSITION DETECTION SYSTEM
12 - 5
12.3 Battery replacement procedure
Before installing a battery, turn off the main circuit power and wait for 15 minutes
or longer until the charge lamp turns off. Then, check the voltage between P+ and
N- with a voltage tester or others. Otherwise, an electric shock may occur. In
addition, when confirming whether the charge lamp is off or not, always confirm it
from the front of the driver.
The internal circuits of the driver may be damaged by static electricity. Always take
the following precautions.
Ground human body and work bench.
Do not touch the conductive areas, such as connector pins and electrical parts,
directly by hand.
Replacing battery with the control circuit power off will erase the absolute position
data.
Before replacing batteries, check that the new batteries are within battery life.
Replace the battery while only control circuit power is on. Replacing battery with the control circuit power
on triggers [AL. 9F.1 Low battery]. However, the absolute position data will not be erased.
