E0558 : Z1-axis spindle inverter error. Re-start the machine.
Error code
E0558
Message
Z1-axis spindle inverter error. Re-start the machine.
What was
detected
The Z1-axis spindle inverter overload, primary side voltage drop,
overcurrent, or regenerative voltage was detected.
During what
operation it
occurred
At any time during Z1-axis spindle rotation.
State after
detection
The Z1- and Z2-axis retreat to their upper ends. The drives for the other
axes come to an immediate stop. The power supply shuts off.
Phenomenon Probable causes Remedy Reference
What to do
The error occurs
when the spindle
starts to rotate.
The inverter internal
voltage setting is too
low.
Contact your
nearest DISCO
Service Office.
Theflangeistoo
heavy or improperly
balanced.
Remove the flange
to check whether
the spindle can
rotate by itself.
Report the check
result to your sales
representative at
the nearest DISCO
Service Office.
The error occurs
during cutting.
Blade abrasiveness is
impaired.
Conduct dressing.
The cutting condition
setup is improper.
Correct the cutting
condition setup.
Recovery
(1) Cancel the alarm.
(2) Turn OFF the machine power.
(3) Wait more than one minute, and then turn the power back ON.

E0576 : Pressure of water dropped.
Error code
E0576
Message
Pressure of deionized water dropped.
What was
detected
The supply pressure of deionized water dropped to under the lower limit
defined on the SENSOR THRESHOLD DATA screen [screen 6.6].
During what
operation it
occurred
While the wheel coolant water is supplied.
State after
detection
The wheel coolant water stops. The spindle continues rotation.
Phenomenon Probable causes Remedy Reference
What to do
The error occurs
even when the
deionized water
supply pressure is
proper.
The wire of the
pressure sensor is
broken.
Contact your
nearest DISCO
Service Office.
The sensor is
defective.
Replace the sensor.
The setting value of
the lower limit is too
high.
Correct the setting
value.
Recovery
(1) Cancel the alarm.
(2) Press the <Sensor> button to call up the SENSOR STATUS screen.
(3) Make sure that the deionized water pressure gauge reads 0.3MPa.
(4) Turn ON the wheel coolant water again.
