Error status #1 The power indicator does not light when the power is turned on.
Probable causes
Check/ repair/ adjust
Parts to be replaced
6.
Malfunction of main
PCB
Turn off the power switch, disconnect connector
P4 (POWER3) and P6 (POWER2) from the motor
PCB, and then turn on the power switch and
check LD2 (red) on the power PCB.
OK if illuminated.
(LD1 (red) on power PCB does not illuminate)
After checking, turn off the power switch, wait for
one minute or more, and then insert P4 and P6
into the motor PCB.

7.
Malfunction of main
PCB 2
Turn off the power switch, disconnect connector
P1 (POWER2) from the main PCB and
connectors P1 (MT
-
ENC), P2 (MAIN) and P3
(PANEL) from the motor PCB, and then turn on
the power switch and check LD2 (red) on the
power PCB.
OK if illuminated.
After checking, turn off the power switch, wait for
one minute or more, and then insert P1 into the
main PCB and P1, P2 and P3 into the motor PCB.

8.
Malfunction of panel PCB
Turn off the power switch, disconnect connector
P1 (POWER2) from the main PCB and
connectors P1 (MT
-
ENC) and P2 (MAIN) from the
motor PCB, and then turn on the power switch
and check LD2 (red) on the power PCB.

9. Poor harness connection
Turn off the power switch, check that connector
P4 (POWER3) is inserted into the motor PCB,
and then turn on the power switch and check the
voltage between terminals 1 and 4 of P4.
OK if approximately 24 V DC.
