Error status #1 The power indicator does not light when the power is turned on.
Probable causes
Check/repair/adjust
Parts to be replaced
1. (Check the LEDs)
Turn on the power switch and check that the
various LEDs illuminate in the following order.
a. LD2 (red) on motor PCB does not illuminate.
→
#1-2, #1-3, #1-4
b. LD2 (red) on power PCB does not illuminate.
→
#1-5, #1-6, #1-7, #1-8
c. LD3 (green) on motor PCB does not
illuminate.
→
#1-9
d. Power indicator on panel does not
illuminate.
→
#1-10
2.
Malfunction of power cord
Turn off the power switch and disconnect the
power supply connector which links the power
cord for the power switch and the motor PCB,
turn on the power switch, and then measure the
voltage between terminals 1 and 3 of the
cord-side connector.
OK if the voltage is the same as mains voltage.
In addition, check that the power supply voltage
at the wall outlet is within the range of the
specification v/- 10%.
After inspecting, turn off the power switch and
connect the power supply connector.
3. Blown
fuse
Turn off the power switch, wait for five minutes
or more, and then remove fuses F1 and F2 from
the motor PCB and check the continuity.
OK if there is continuity.

(10A-250V)
4. Malfunction of motor PCB 1
Turn off the power switch and remove P2
(DCIN) from the power PCB, turn the power
back on, and then check LD2 (red) on the motor
PCB.
OK if illuminated.
After checking, turn off the power switch, wait
for five minutes or more, and then insert P2 into
the power PCB.
Turn the power back on, and then with P2
inserted into the power PCB, check the voltage
between terminals 1 and 3 of P2.
OK if 240 to 380V DC.

5. Malfunction of power PCB
Turn off the power switch and disconnect
connector P1 (POWER2) from the main PCB
and connectors 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.
After checking, turn off the power switch, wait
for one minute or more, and then insert P1 into
the main PCB and P4 and P6 into the motor
PCB.
