1. DESCRIPTION This machine has the following two types of alarms and displays them by different methods. These alarms are described on the pages that follow. Machine alarms: Alarms and warnings caused by the operation of the component parts and safety devices of the machine Executor alarms: Alarms related to regular-shaped hole macro commands The machine alarms come in two types: alarms that stop the operation of the machine and warnings that do not stop the operation of the machine.

NOTE

For the alarm numbers that appear on the MESSAGE display but not described in this manual, refer to the following manuals attached to the machine:

Alarm numbers 4xxx: Maintenance manual of Fanuc Laser C Series Other alarm numbers: Maintenance manual of Fanuc Series 160i-Model B

Some optional units have their own alarms. For these alarms, refer to the operation manuals of such optional units.

2. MACHINE ALARMS When a machine alarm occurs, the ALARM light on the NC control panel illuminates, and the machine comes to a temporary stop or total stop. Or the WARNING light flashes, and the machine continues to operate. The description of each machine alarm can be checked on the MESSAGE display. The machine alarms occur in two types. One type allows the machine to resume the operation once the cause of the alarm is removed, while the other type calls for the NC unit to be reset. When a machine alarm of the latter type occurs, remedy its cause, return the cursor to the beginning of the program, and retry the laser cutting operation.

No. Message Cause and remedy

2500 MAIN AIR PRESSURE DOWN Compressed air is supplied at less than 0.4 MPa {4.0 kgf/cm² or 57 psi}. Return the air pressure to normal, and press the ALARM RESET button to clear the alarm. Check the air supply pressure and piping. When the NC unit is in the MANUAL or RETRACT mode, this alarm message is handled as a warning.

2501 CIRCUIT PROTECTOR TRIP A circuit protector in the NC unit has been tripped by an overload in the 100 VAC or 24 VDC circuit. Turn the machine circuit breaker switch to OFF and the tripped circuit protector to ON. Return the machine circuit breaker switch back to ON, and press the NC RESET button to clear the alarm. If the cause of the trip is not known, contact AMADA.

2502 DEAD ZONE One of the workclamps has entered the dead zone where it is likely to strike the laser head. Change the NC mode to MANUAL, and move the Z-axis in the plus direction to clear the alarm. Reposition the workclamp, change the cutting start point, or correct the program.

2503 SAFETY STOP A light curtain has operated, or a sliding door of the partitions has been opened. Remove the cause, and press the SAFETY DEVICE RESET button to clear the alarm.

2504 CUTTING HEAD CONNECTION The laser head has struck the material. Change the NC mode to MANUAL, press the +Z button to raise the Z-axis, and properly install the laser head. Press the NC RESET button to clear the alarm. Since the nozzle is likely to be misaligned, adjust its center.

2505 MAIN AIR PRESSURE SWITCH NG

4. ALARM DETAILS 4-1. Details of machine alarm No. 2507

(INTERLOCK–Z) and No. 2527 (SENSING ALARM), and NC alarm (OVERTRAVEL–Z)

The Z-axis tracking sensor may be unable to properly follow the material in the cases described below. As a result, the machine alarm No. 2507 (INTERLOCK–Z), the machine alarm No. 2527 (SENSING ALARM), or cutting failure may occur. The machine alarm No. 2507 (INTERLOCK–Z) occurs when the Z-axis moves beyond the travel range in the minus direction as the sensor follows the material.

4-1-1. CUTTING NEAR MATERIAL EDGE AND NEAR ALREADY CUT EDGE

When cutting near the material edge as shown below, the distance from the edge must be at least 10 mm {0.4 in.}. When the distance from the material edge is short, the response of the sensor is small. Consequently, the material is judged to be positioned further than it actually is, and the nozzle gap is decreased. When the nozzle gap varies so much as to cause a cutting problem or alarm, press and illuminate the TRACE OFF button to cancel the tracing feature and cut the material without using the sensor.

4-1-2. CUTTING FROM MATERIAL EDGE (NARROW STRIPS, ETC.) When cutting is started or ended outside the material edge as shown below, locate the start or end point at 1 mm {0.04 in.} or less from the material edge. When the distance from the material edge is short, the response of the sensor is small. Consequently, the material is judged to be positioned further than it actually is, and the nozzle gap is decreased. When the nozzle gap varies so much as to cause a cutting problem or alarm or when the sensor strikes against the material edge, press and illuminate the TRACE OFF button to cancel the tracing feature and cut the material without using the sensor.

NOTE

In Clean Cut, Aluminum Cut, EZ Cut, or other cutting modes with a narrow nozzle gap, cutting cannot be started from the material edge.

4-1-3. CUTTING OR PASSING OVER ALREADY CUT PORTION When cutting or passing over an already cut portion as shown below, the response of the sensor is small. Consequently, the material is judged to be positioned further than it actually is, and the nozzle gap is decreased. When the nozzle gap varies so much as to cause a cutting problem or alarm or when the sensor strikes against an already cut material edge, press and illuminate the TRACE OFF button to cancel the tracing feature and cut the material without using the sensor.

4-1-4. CLEARANCE IN CUTTING END POSITION When cutting with a clearance at the end point as shown below, make the end point shorter than the approach point. When the hole diameter is 15 mm {0.59 in.} or larger and the end point is located apart, the laser beam enters deep into the already cut portion. In this case, the response of the sensor is small. Consequently, the material is judged to be positioned further than it actually is, and the nozzle gap is decreased. When the nozzle gap varies so much as to cause a cutting problem or alarm or when the sensor strikes against an already cut material edge, press and illuminate the TRACE OFF button to cancel the tracing feature and cut the material without using the sensor.

4-1-5. STEP AROUND CUTTING AREA When there is a step around the cutting area as shown below, the nozzle gap varies. This variation of the nozzle gap changes with the height H and the distance L. When the nozzle gap varies so much as to cause a cutting problem, press and illuminate the TRACE OFF button to cancel the tracing feature and cut the material without using the sensor.

4-1-6. OCCURRENCE OF PLASMA DURING CUTTING When plasma occurs during cutting, the electrostatic capacitance-type sensor becomes unstable in its detection function. When a strong flash (of bluish white light) occurs to cause the Z-axis to move unstably, produce an alarm, or touch the material, press and illuminate the TRACE OFF button to cancel the tracing feature and cut the material without using the sensor.

4-1-7. CUTTING INCLINED SURFACE Cut an inclined surface at one of the speeds described below. A higher cutting speed may produce a poor cut or bring the sensor into contact with the material. The inclined surface cannot be cut if its angle of gradient is greater than 10°.

Angle of gradient Maximum cutting speed

5° 5000 mm/min (for nozzle gap of 1.5 mm)

196.9 ipm (for nozzle gap of 0.059 in.)

10° 3000 mm/min (for nozzle gap of 1.5 mm)

118.1 ipm (for nozzle gap of 0.059 in.)

4-1-8. CUTTING BOWED OR VIBRATING MATERIAL When the material is extremely bowed or when the material is 1 mm {0.04 in.} or thinner and vibrates at its edge under the action of axis travel or assist gas, an alarm is likely to occur. When an alarm occurs, prepare jigs to fix the material, and cut the material using the jigs. If an alarm still occurs despite the use of the jigs, press and illuminate the TRACE OFF button to cancel the tracing feature and cut the material without using the sensor.
