Fault: Power Lost
Signal !!
“0” → ”9”
→ ”9” →
”0” is
displayed
by
rotating.
The Power Lost signal
of the YPS power unit
was detected.
YIF circuit
board
failure
-Turn the power OFF then back ON.
-If the error occurs again, make sure that
the following connectors are connected
properly and there is no wiring error
(disconnection).
(1) YPS-CN158
(2) YRK-CN5
-If the error occurs again though check
the wiring, remove all the circuit boards
from the CPU rack and reinstall them.
-If the error occurs again though reinstall
them, replace the YIF circuit board. After
replacing the board, load the CMOS.BIN
file saved before the error occurs or the
CMOSBK.BIN file saved in the automatic
backup function in the maintenance
mode. (refer to *4)
Fault: I/O(JL098)
Hardware Error!!
Initialization of JL098
incorporated in the
robot I/F circuit
board(YIF) was failed.
YIF circuit
board
failure
-Turn the power OFF then back ON.
-If the error occurs again, remove the YIF
circuit board from the CPU rack and
reinstall it.
-If the error occurs again though reinstall
them, replace the YIF circuit board. After
replacing the board, load the CMOS.BIN
file saved before the error occurs or the
CMOSBK.BIN file saved in the automatic
backup function in the maintenance
mode. (refer to *4)
Fault:
SERVO(JL101)
Hardware Error!!
Initialization of JL101
incorporated in the
robot I/F circuit
board(YIF) was failed.
YIF circuit
board
failure
-Turn the power OFF then back ON.
-If the error occurs again, remove the M
III cable of the YIF circuit board and
insert it again.
-If the error occurs again though remove
and then insert the M III cable, replace
the YIF circuit board. After replacing the
board, load the COMS.BIN file saved
before the error occurs or the
CMOSBK.BIN file saved in the automatic
backup function in the maintenance
mode.(refer to *4)
Fault: Watch Dog
TimeOut Signal !!
An error was detected
in the watch dog circuit
(which supervises the
proper operation of the
circuit board)
incorporated in the
robot I/F circuit board.
YIF circuit
board
failure
-Turn the power OFF then back ON.
-If the error occurs again, remove the YIF
circuit board from the CPU rack and
reinstall it.
-If the error occurs again though reinstall
them, replace the YIF circuit board. After
replacing the board, load the CMOS.BIN
file saved before the error occurs or the
CMOSBK.BIN file saved in the automatic
backup function in the maintenance
mode. (refer to *4)
