Probable causes
1.
With error code [E.12], the
emergency stop switch is
activated, or it is defective.
2.
With error code [E.21], the
machine is malfunctioning.
3.
With error code [E.60], the panel
circuit board is defective.
4.
With error code [E.61], the
control circuit board is defective.
5.
With error code [E.90], the power
supply voltage has sharply
dropped.
6.
With error code [E.91], the power
supply voltage has sharply risen.
9.
With error code [E.c2], the
control box has overheated.
• Clean the air intake of the control box.
• The temperature detector is screwed into the
heatsink on the control circuit board.
Turn on the
power after the temperature of the heatsink falls.
If the error still appears, the control circuit board
is defective.
• Note: If the machine is operating with the control
box open, the heatsink will overheat, resultantly,
error [E.c2] will occur.
Control circuit
board
8.
With error code [E.c1], the box
cooling fan (at the left when
viewed from the front) is
defective.
• Check whether any thread scraps are not
entangled in the cooling fan.
• Check that connector P10 (FAN-R) on the control
circuit board is securely inserted.
Fan motor
assembly
7.
With error code [E.c0], the [MT]
PROM on the control circuit
board is defective.
10.
With error code [E.c3],
overcurrent has occurred in X-
pulse motor.
Check/repair/adjust
• Check that connector P3 (HEAD) on the control
circuit board is securely inserted and the
emergency stop switch is correctly wired.
• Check that grounding is securely made and there
is no equipment that generates strong electrical
noise nearby.
• Turn on the power again.
If nothing changes,
panel PCB is defective.
• Turn on the power again.
If nothing changes,
control PCB is defective.
• Check that the voltage of a socket is within
±
10%
of specified voltage.
• Refer to #d1-1, -1, -3
• Refer to #1.1-5
• Refer to #1.1-13
• Check that connector P7 (XPM) on the control
circuit board is securely inserted and the X-pulse
motor is securely plugged in.
• Refer to #1.1-2
