2-3. Remedies for Errors Requiring Emergent Stop
E0002 : EM switch pressed.
Error code
E0002
Message
EM switch pressed.
What was
detected
The signal input from the EMO switch was detected.
During what
operation it
occurred
At any time.
State after
detection
The Z-axis retreats to the upper end and the power turns OFF.
The other axis drive systems come to an immediate stop.
(If the error occurs during spindle rotation, the power turns OFF and the
spindle enters the free running state with the covers locked.)
Phenomenon Probable causes Remedy Reference
What to do
EMO operation is
not actuated even
after the EMO
switch is pressed.
The switch is
defective.
Replace the switch.
Contact your
nearest DISCO
Service Office.
The wiring is
shorted.
Contact your
nearest DISCO
Service Office.
The EMO operation
is actuated although
the EMO switch is
OFF.
The switch is
defective.
Replace the switch.
Contact your
nearest DISCO
Service Office.
The wiring is broken. Contact your
nearest DISCO
Service Office.
Recovery
(1) Turn the EMO switch in the direction of the arrow to put it back to the

E0003 : Insufficient main air ... Reinitialize.
Error code
E0003
Message
Insufficient main air ... Reinitialize.
What was
detected
The air pressure dropped to below 400 kPa and there was an input on the
pressure sensor.
During what
operation it
occurred
At any time.
State after
detection
The Z-axis retreats to the upper end and the spindle stops. The other axis
drive systems come to an immediate stop.
Phenomenon Probable causes Remedy Reference
What to do
The error occurs
when the supply air
pressure is lower
than 0.4MPa.
The supply air
pressure is too low.
Correct the air
supply pressure.
Check that the
supply air piping is
not clogged or bent.
The error occurs
when the supply air
pressure is 0.4MPa
or higher.
The pressure sensor
limit setting is
improper.
Set the pressure
sensor to 0.4MPa.
Recovery
(1) Cancel the alarm.
(2) Press the <Sensor> button to call up the SENSOR STATUS screen.
(3) Make sure that the air pressure gauge reads 0.5MPa.
(4) Effect system initialization.

E0007 : UPS has been actuated.
Error code
E0007
Optional accessory
Message
UPS has been actuated.
What was
detected
The low voltage level of 170 or less continued for 2 seconds or longer and
then the UPS unit was actuated.
During what
operation it
occurred
At any time.
State after
detection
The Z-axis retreats to the upper end. The spindle and spinner will stop
within 20 seconds. Other axes come to an immediate stop.
Phenomenon Probable causes Remedy Reference
What to do
The error recurs
when the power is
turned back ON.
The facility power
supply has failed or
its voltage has
dropped.
Contact facility
maintenance
personnel and have
them check the
power source
voltage.
Do not touch the
machine for a
period of 90 s after
machine power
OFF because the
UPS unit supplies a
hazardous voltage
to the machine.
Recovery
(1) Cancel the alarm.
(2) Turn OFF the machine power.
(3) Wait more than one minute and then turn the power back ON.
(4) Effect system initialization.
