1.Emergency Alarm

1.12001 Emg. Button or Axes Emergency

1)Description

The Emergency Stop push-button switch on the operation panel is pressed down, or at least one Emergency Stop limit switch for the axes is tripped.

2)Cause of problem

The Emergency Stop push-button switch on any of the main OP, the tool magazine OP, or the chip conveyor is pressed down.

The Limit switch for an emergency stop located for each axis (X, Y, Z, W) is pressed down.

An error in the Emergency Stop switch on the OP, or the Emergency Stop limit switch for each axis, or other related parts

Disconnection of the wiring

3)Action

Check if the red mushroom push-button switch on the main OP, the tool magazine OP, or the chip conveyor is pressed down, and if so, turn the switch counter clockwise to release it.

If the Limit switch for any axis (X, Y, Z, or W) is tripped, press both the Machine Ready

switch and the Emergency Release switch simultaneously to enter the Machine Ready state. (If you want to return to the emergency stop state, simply release the switch.) Then, move the problem-making axis in jog or handle mode so as to remove it from the emergency stop limit switch.

Check the Emergency Stop push-button switch on the main OP, the Emergency Stop limit switch on the axis, and other related parts for any problem. Repair or replace the defective

part if necessary.

Disconnection of the wiring

Refer to the circuit diagram and use the electric tester to check each terminal block. If you find an error, repair or replace the defective part.

1.22002 Spindle Alarm is Detected

1)Description

There occurred an alarm from the main spindle drive unit.

2)Cause of problem

An error found in the main spindle drive unit

An error found in the spindle motor, power cable or signal cables

3)Action

Check the alarm number that is displayed on the main spindle drive unit of the electric cabinet. Take a necessary measure according to the alarm number.

Refer to "Troubleshooting by the spindle amplifier alarm" in the appendix.

Check the spindle motor for the 3-phase power source and the feedback cable if there is a problem.

1.32003 Power Circuit Overcurrent Detected

1)Description

The circuit protector that is installed in the electric cabinet is tripped.

2)Cause of problem

The circuit protector is triggered. (Abnormal signal is detected)An error in power control

The circuit protector has an error itself.

3)Action

Find out the cause that the circuit protector is tripped.

(ex) If QF22 is tripped, check the secondary circuit (L+) of QF22 if it's short-circuited, and take a necessary measure before turning the circuit protector back on.

If the alarm occurs but no circuit protector is tripped, measure the resistance of each contact point, and find out the defective circuit protector, and replace it with a new one.

If you measure the resistance on the contact point of the circuit protector that is turned on, you will get "0" ohm if it's normal.

If you have found nothing wrong in steps and above, that is thought to be caused by the I/O circuit board. Check the I/O board and repair or replace it if necessary.

1.42004 Hyd. Pump Motor Overload

1)Description

Hyd. An excessive electric current is detected in the hydraulic pump motor or the lubricant pump motor of the spindle head.

2)Cause of problem

The hydraulic pump motor, the lubricant pump motor of the spindle head, or the power cable is burnt out.

The circuit breaker that detects the excessive current is overloaded or defective itself.

3)Action

Check the hydraulic pump motor, the lubricant pump motor of the spindle head, or the

power cable if there is a problem. Repair or replace the defective part if necessary.

Check the circuit breaker for the load settings and make correction if necessary. If the circuit breaker itself has an error, replace it with a new one.

(You can detect a defective circuit breaker by checking the resistance on either circuit of M212 or 1L+)

1.72008 PSM Contact Check Error

1)Description

There occurred an error while KM10 magnetic contactor was operating.

2)Cause of problem

The operation of KM10 did not comply with the intended signal.

3)Action

The check signal (X9.6) of the magnetic contactor should turn on only while KM10 is operating.

Set "Keep Relay K17.0" to 1 if you want to enable the option of Motor Power On/Off.

If you set "K17.0=(1)" to enable the option of Motor Power ON/OFF, KM10 magnetic contactor turns off if the door is open, and turns on if the door is close.

2.32033 Air Pressure down Alarm

1)Description

The air pressure switch is tripped because the air pressure falls below the specified value.

2)Cause of problem

The factory-supplied air pressure falls below the standard (4kg).

The air pressure switch or any of its parts is defective.

3)Action

Increase the factory-supplied air pressure to more than 5kg/ .

▪Check the air pressure measurement displayed on the gauge of the air service unit, and if it's below 4kg/ , turn the air pressure handle to the right. If the gauge does not increase

any further, this indicates the current air pressure is not appropriate.

Check the air pressure switch, wiring and I/O module if there is no error. And make repair or replacement if necessary.
