If the monitor lamp blinks at 1 Hz, the EPROM is faulty. If the flashing frequency is 2 Hz, the PLC is faulty. If it flashes at 4Hz, keep the battery alarm, indicating that the voltage is insufficient. Indicates that the interface board 03731 of the operation panel is faulty or the CRT is faulty. 1) No basic screen display after power is turned on (a) No monitor light on the board number 03840. (b) The monitor light on the 03840 board is on. 1 The monitor light flashes. If the blinking frequency of the monitor light is 1 Hz, the EPROM has a fault; if the flashing frequency is 2 Hz, the PLC has a fault; if it flashes at a frequency of 4 Hz, the battery alarm is maintained, indicating that the voltage is insufficient. 2) Displaying confusion on the CRT (a) Keep the battery (lithium battery) voltage too low, and the 711 alarm can usually be displayed. 3) The program cannot be started in automatic mode (a) In this case, an alarm No. 351 is generated, indicating that the machine is not returned to the reference point after the CNC system is started. 4) Feed axis motion failure (a) The feed axis cannot move. The reasons for this failure are: 5) Spindle failure If the actual spindle speed exceeds the maximum speed of the selected gear, an alarm No. 225 is generated; if the spindle position loop monitoring fails, an alarm No. 224 occurs. 6) V·24 serial interface alarm (a) When data has not been sent or received within 20 seconds: Bluetooth Speaker,Portable Bluetooth Speaker,Mini Bluetooth Speaker,bluetooth Wireless Speaker,portable wireless speaker Shenzhen Lanejoy Technology Co.,LTD , http://www.brassinsert.net
2 The monitor light is left and right. Indicates that the interface board 03731 of the operation panel is faulty or the CRT is faulty.
3 The monitor light is always on. The usual causes of such failures are: CPU failure; EPROM failure; system bus (ie backplane) failure, incorrect board settings, machine data errors, and circuit boards (eg memory boards, coupling boards, The hardware of the measuring board) is faulty.
(b) The storage area is confusing due to the power strip or storage being pulled out. This is a soft fault and can be eliminated by simply clearing and re-entering the CNC internal program.
(c) A hardware failure on the power board or memory board causes the program to display confusion.
(d) If the alarm No. 513 is displayed on the CRT, the capacity of the memory is insufficient.
(b) The system is in an automatic hold state.
(c) It is forbidden to start the cycle. Check the interface signal Q64.3 between the PLC and the NC.
1 operation is wrong;
2 The signal transmitted from the PLC to the NC is not normal;
The 3-position control board is faulty (such as the 03350, 03325, 03315 boards are faulty).
4 An alarm No. 22 occurred, indicating that the position loop is not ready.
5 The measurement system is faulty. For example, alarms 108, 118, 128, 138 are generated, which is caused by the measurement sensor being too dirty. If a 104, 114, 124, 134 alarm is generated, the position loop has a hardware failure.
6 The motion axis is in the software limit state. Simply lift the machine axis in the opposite direction to release it.
7 When the alarms 101, 111, 121, and 131 occur, the machine tool is in mechanical clamping state.
(b) The feed axis is not moving continuously.
(c) Feed axis flutter.
1 The speed loop and current loop parameters of the feed drive unit are not optimized or the AC motor phase loss or the speed measuring component is damaged, which can cause the feed shaft to vibrate.
The position control board of the 2CNC system is faulty.
3 The mechanism has too much friction.
4 The numerical control machine data is incorrect. The correct setting of the machine data is as follows.
(d) The feed axis is out of control.
1 If there is an alarm of 101, 111, 121, 131, please check the clamping.
2 If there are alarms 102, 112, 122, 132, the command value is too high.
3 The feed drive unit is faulty.
4 The numerical control machine data setting is wrong, causing the position control loop to be positive feedback.
The polarity of the command line of the 5CNC device to the drive unit is incorrect.
(e) No. 103-133 alarm. This is the contour monitoring alarm. The speed loop parameters are not optimized or the KV factor is too large.
(f) No. 105~135 alarm. The position drift is too large. When the shift amount exceeds 500 mv, the drift compensation parameters N230 to N233 are checked.
1 external equipment failure;
2 The cable is incorrect;
The 303840 board is faulty.
(b) The punched tape information cannot be entered for the following reasons:
1 The key switch on the operation panel is in the off position, which causes the tape program to be unable to input;
2 If the data protection switch on the 0384 board is not in the release position, the data tape cannot be input;
3 If the subprograms L80 to L99 and L900 to L999 cannot be input, it is mostly caused by the PLC and NC interface signal Q64·3 being "1" (loop disabled).
(c) Stop bit error.
1 baud rate setting error;
2 the reader is faulty;
3 Machine data error.
