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.
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.
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.
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.
Replace the PCB-ASSY-HCB1M.
Replace the PCB-ASSY-IPB5-100.
Replace all four FFCs.
Replace the robot cable.
