6.3.2 AXG1A Remote Transmitter
IMPORTANT
• Removing and installing the cover are necessary for
hardware switches. Perform removing and installing the
cover as described in Subsection 4.4.5. When opening
the cover, wait for more than 20 minutes after turning off
the power. This work must be carried out by the trained
personnel having knowledge of safety standard.
• To preserve the safety, do not touch the electrical circuit
and the cables except the setting switches.
(1) Remove the cover (See Figure 6.3.3).
Figure 6.3.3 Removing the cover
(2) Set the switches.
Figure 6.3.4 Hardware switches
(3) Install the cover.
NOTE
On the front of the amplifier, the burnout switch (i.e.,
Switch 1-1) and the write protect switch (i.e., Switch 1-2)
are located adjacent to each other. Accordingly, special
care should be taken when making switch settings.
(1) Setting of Burnout Switch
The burnout function sets the direction of current output in
situations where the CPU has become damaged.
Upon shipment from the manufacturing plant, the burnout
direction is set to High (i.e., >21.6 mA); however, in cases
where the optional codes C1 or C2 have been specified,
the output direction will be set to Low (i.e., <2.4 mA).
Modification of the burnout direction must be carried out
using the burnout switch (i.e., Switch 1-1) (See Figure 6.3.4).

(2) Setting of Write Protect Switch
The write protect function is to prevent the overwriting of
parameters.
Write protection can be carried out using either the write
protect switch (Switch 1-2) (See Figure 6.3.4) or software
F0612.ai
function with parameter setting.
If either of these items is activated, the overwriting of
parameters will be prohibited.

• If the hardware switch is set to "ON", the condition of
preventing parameter overwriting kept until the switch
is set to "OFF".
• For write protect by parameter (software), read the
user's manual of applicable communication type as
listed in Table 1.1.
