Fault phenomenon: When a CNC machining special machine is in the process of automatic operation, when it is executed to G 90G01Z0; this sentence occurs without any reason. Performing a system reset and restarting the machining program is also performed to G 90G01Z0; when this program is stopped, the operation is stopped. At this time, there is no alarm information.

Troubleshooting: In the absence of any alarm information, call up the diagnostic function screen, hoping to find a clue to the fault. When viewing the diagnostic function screen, it was found that the diagnosis number 005 system is interlocking with each servo axis or the start lock signal is input to 1. Then check the servo axis interlock signal of the above PMC, and find that 6130.0 is 0, and the Z axis is the first axis defined in the system. Look up the ladder diagram and see the reason why the coil 130.0 fails to be connected. Finally, it is found that the turret is lifted. The detection/proximity of the proximity switch is 1 at the same time. It is found that the turret is actually falling into position, and the proximity switch for lifting detection emits a false signal because it is stained with iron filings, so the PMC program determines the safety of the Z-axis. The movement condition is not met. After the proximity switch is cleared, the coil 6130.0 is set to 1, and the interlock state of the Z axis is released, and the fault is eliminated.
(4) No. 350 alarm, which is caused by an abnormality in the control part of the serial pulse encoder. At this time, the alarm status displayed by the diagnostic numbers 202 and 204 in the diagnostic function can be used to determine the specific cause of the fault.
(5) Alarm No. 351, which is caused by an abnormality in the communication between the serial pulse encoder and the module. At this time, the alarm status displayed by the diagnosis number 203 in the diagnostic function can be used to determine the specific cause of the fault.
(6) No. 400 alarm, which is caused by the system detecting the overheating of the servo module or servo motor. The specific cause of the fault can be determined using the alarm status shown in Diagnostics No. 200 and 201 in the Diagnostics function.
(7) No. 414 alarm, which is caused by an abnormality in the servo module or servo motor. At this time, the alarm status displayed by the diagnostic numbers 200, 201 and 204 in the diagnostic function and the alarm number displayed by the LED on the servo module can be used to determine the specific cause of the fault.
(8) No. 416 alarm, which is caused by the signal disconnection or short circuit of the position detector. At this time, the alarm status displayed by diagnosis numbers 200 and 201 in the diagnostic function can be used to determine the specific cause of the fault.
(9) No. 417 alarm, which is caused by abnormal setting of system servo parameters. At this time, the alarm status displayed by the diagnostic numbers 203 and 280 in the diagnostic function can be used to determine the specific cause of the fault.
(10) Alarm No. 749, which is caused by an abnormality in the spindle servo module. At this time, the alarm status displayed by the diagnosis number 408 in the diagnostic function can be used to determine the specific cause of the fault.
(11) No. 750 alarm, which is caused by the spindle servo module not reaching the normal starting state when the serial spindle system is energized. At this time, the alarm status displayed by diagnosis number 409 in the diagnostic function can be used to determine the specific cause of the fault.
3, can not run by hand
If the handwheel operation cannot be performed, there may be the following reasons:
The servo is not activated (not ready).
The manual pulse generator is not properly connected to the built-in I/O interface or I/O module.
The I/O interface of the built-in I/O interface or I/O module is not assigned or is not correctly assigned.
The relevant signal is not input due to a parameter setting error.
Take measures:
1) Check if the LED display on the servo amplifier is “0â€. If a number other than "0" is displayed, the servo is not activated.
2) Check if the cable is broken or shorted;
3) Check if the handwheel malfunctions (the manual pulse generator signal is correct)
4) Check the I/OLink assignment of the I/O module. 5) Check the parameters and input signals. Check the status of the CNC in the lower left corner of the CRT. The state of the CNC should be in the HND state. Otherwise, the mode selection is incorrect. Further through the PMC diagnostic function (PMCDGN) view mode selection: hand wheel mode is G0043 "MD4 = 1, MD2 = 0, MD0 = 0"
Check the handwheel feed axis selection signal to check the handwheel feedrate override selection, PMC's PCDGN to confirm the signal: G0019 MP2 and MP1 bits.
The feed of the indexing axis of the indexing table cannot be performed.
