Mitsubishi M80 system battery is out of power, how to lose the coordinate zero point? Tip: The absolute value is wrong (servo alarm 25...

Setting the absolute value zero point: a. First, set the parameter #2049. The setting method is divided into two situations: if it is the absolute value zero point for the first time, #2049 is set to "4" absolute value reference point mode, and the machine tool is powered off, (servo It also needs to be turned off) and then turned on the power. Otherwise, the servo digital tube will call the alarm on the 25th.

The absolute position is lost due to the battery failure. The zero position does not match the mechanical design. During the maintenance process, the motor, screw rod, etc. were disassembled, resulting in the loss of the absolute value position.

It may be the loss of the origin position due to the low battery voltage. The origin needs to be reset.

Is it a pseudo-absolute value system with a battery? If the absolute position is lost, the battery must be out of power. Once the power is cut off or the machine is crashed, there will be a pulse accumulation error. Countermeasure: Change the battery first.

In the second case, if you have returned to the absolute value of zero before, you hope to return to zero again. The following situations must return to zero again: the absolute position is lost due to the battery failure. The zero position does not match the mechanical design. During the maintenance process, the motor, screw rod, etc. were disassembled, resulting in the loss of the absolute value position.

May I ask how to cut the tool of Mitsubishi CNC system?

In the correct part, press the menu to the processing part, and the parameter 8002 can be entered to zero.

Manual knife steps: x0dx0a can be of any size of 6mm or 8mm, etc. It is better to use an integer knife stick, which should be a standard point. X0dx0a (1) Use 6MM, the Z axis is manually lowered to about 6MM from the surface of the workpiece, and the handwheel movement unit is changed to 0.01.

Mitsubishi's knife is the simplest. When Z finds the position you want, assuming that what you want is a 0-point surface, then select the knife length option in the tool interface, then press the Z key, move the cursor to the ( ) behind Z and enter 0, and then press the OK key to complete the knife on the Z side.

Trial cutting method is the most widely used method in practice. The following is an example of the RFCZ12 lathe using MITSUBISHI 50L numerical control system to introduce the specific operation method.After the workpiece and tool are clamped, the spindle is driven to rotate, and the tool holder is moved to the outer circle of the workpiece.

Modified the coordinate offset! There are two cases. One is to use a 10mm tool stick to indirectly face the tool on the surface of the workpiece, and then -10 down in the coordinate offset or the Z coordinate of G54. Another situation is to face the knife on another unrelelegant plane.

What are the types of abnormal stop of EMG in Mitsubishi M70 system

1. It may be caused by motor overload, abnormal stop. It may also be caused by damage to the motor bearing.

2. Press the RELEASER button and shake the handwheel at the same time. Situation description: After hitting the knife, the Z axis did not return to zero, and the program went directly. G91 G28Z0 stopped urgently when it returned to the mechanical zero.When it doesn't work to turn off the power. Be sure to return to zero and be sure to re-top the Z axis.

3. Press the OT/EMG RELEASER on the EMG button by hand, flash the red light button, and shake the handwheel at the same time. After hitting the knife, the Z axis does not return to zero, and go directly to the program. When G91 G28Z0 returns to the mechanical zero, it stops urgently. When the power is turned off, it returns to zero again, and the Z axis to the knife again. , the stroke switch is not in contact with the positioning iron, just adjust the gap between the two.

4. Regarding his problem unlocking, you should first turn off the whole machine. Restart your Mitsubishi machine. Get up and get angry. There may be some problems in the future. It has returned to the starting state. The factory settings are out, and you can adjust them.

5. Mitsubishi System Processing Center G Instruction: M70 automatic tool establishment.M71 knife sleeve down. M72 knife-changing arm 60°. M73 spindle loosening knife. M74 changing arm 180°. Change the parameters of K4 and K5 to 1 in the MDI state, and then press the start button in the manual state. It can complete the change action step by step.
