<Action>
Check the Items to be Checked on the table below, and perform the actions starting from the top
until the problem is solved.
Note:
For this error, be sure to perform the actions 1 to 5.
No Items to be Checked Action
1 The width of the V-shaped folded part
on the PCB-ASSY-HCB1M-side FFC Check that the width of the V-shaped folded part on the FFC
is proper. If not, adjust it. For the adjustment procedure, see
6.8.4 PCB-ASSY-HCB1M .
2
FFC’s external damage
Check the following to ensure that the FFC is not damaged.
-
FFC’s terminal is detached from its base.
-
FFC’s edges have not been abraded by friction.
If the FFC is damaged, replace it.
3 FFC
’s connector connection
Reconnect the FFC on both the PCB-ASSY-HCB1M side
and the PCB-ASSY-IPB5-100 side.
If the cable terminals are smeared, softly wipe them with a
soft cloth or lint-free paper dampened with ethanol before
connecting them.
4
Robot cable’s connector connection
Reconnect the robot cable on both the PCB-ASSY-HCB1M
side and PCB-ASSY-ACT3 side.
Before connecting, check that the connector terminals and
cable connection part are not disconnected. If a connection
failure is found, replace the robot cable.
