11.7.2 Precautions for using USB communication function
Note the following to prevent an electric shock and malfunction of the servo amplifier.
(1) Power connection of personal computers
Connect your personal computer with the following procedures.
(a) When you use a personal computer with AC power supply
1) When using a personal computer with a three-core power plug or power plug with grounding wire,
use a three-pin socket or ground the grounding wire.
2) When your personal computer has two-core plug and has no grounding wire, connect the
personal computer to the servo amplifier with the following procedures.
a) Disconnect the power plug of the personal computer from an AC power socket.
b) Check that the power plug was disconnected and connect the device to the servo amplifier.
c) Connect the power plug of the personal computer to the AC power socket.
(b) When you use a personal computer with battery
You can use as it is.
(2) Connection with other devices using servo amplifier communication function
When the servo amplifier is charged with electricity due to connection with a personal computer and the
charged servo amplifier is connected with other devices, the servo amplifier or the connected devices
may malfunction. Connect the servo amplifier and other devices with the following procedures.
(a) Shut off the power of the device for connecting with the servo amplifier.
(b) Shut off the power of the servo amplifier which was connected with the personal computer and check
the charge lamp is off.
(c) Connect the device with the servo amplifier.
(d) Turn on the power of the servo amplifier and the device.

(3) Battery replacement procedure
WARNING
Before replacing 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 servo amplifier.
CAUTION
The internal circuits of the servo amplifier 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.
POINT
Replacing battery with the control circuit power off will erase the absolute
position data.
Before replacing batteries, check that the new battery is 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.
