Hi,

If it is M64M, believe it has the HR113 CPU board, check if the WDER red LED glows during this problem. It is on the right hand side of the 7-segment display, in the bottom side of the CNC...

Hi CNC Viking,

Nice to learn that the RS232 problem is solved.

Regarding orientation, please ref. the attached document for your reference.

I believe the Orientation is done by Megnasensor...

Hi,

If you go to Alarm History page of the Spindle Drive, you can see any other alarm has occurred, just before alarm 33.
This you can judge with the Work Time, in the column adjacent to alarm...

Hi,

When this error window pops up, you can check the program name for which this error happens.
Depending on this program name & your observations(if it appears after a particular command or...

Hi,

Which controller? I have a backup of old machine with M50 control.

Hi,

Some more details for you as attached,

You can check the feedback from motor detector, Scale. For this you can go to the attached Drive monitor page & then page down.
Check Motor end...

Hi,


7) About the polarity. What´s you are tell me ??? Is about the movement ??? CW or CCW direction ???

You can see the difference between Motor encoder & scale feedbacks in the Servo...

Hi,

You need to collect the following data.

1) Confirm that the Scale works on +5V supply, maintain the required cable resistance & other specifications, so that the drive side power supply is...

Hi,

Sorry for the delay in reply.

For CNC RAM clear, below procedure is required. It will be the first step to recover from this error, please confirm all backup is available before doing it.
...

Hi,

Normally the +ve side is the Home position, so if the axis slows down during +ve direction seems ok.

If you can find the PLC Diagnosis Monitor, check for X001A input for Z-axis Home L.S.
...

Thank you,

Hi,

From your feedback the Encoder seems to be Incremental, because it slows down after Home Limit switch is released.

Normally for Absolute Encoder, the home return is high speed, but of...

Hi,

Sorry for the delay in reply.

Do you have any idea, if the spindle is analog (with some inverter) or a Mitsubishi Spindle drive (MDS A/B ... SPJ OR SPJ2 OR SP)?

If it a mitsubishi...

Hi,

You have a no of steps to do as below,

1) Replace with new batteries.
2) NC Memory Clear with the CS1 / CS2 rotary switch.
3) Change Language par. 1043 = 1 to English or for any other...

Hi,

I feel you are on the right track. If the turret is over shooting the commanded station & stops in between with below alarm, encoder feedback seems faulty.

Hi,

640M is the Mazatrol CNC control, with Mitsubishi 600 series H/w. It has HDD, Front IC Card (PCMCIA), normally standard. The HDD program running & Back Ethernet & IC Card PCMCIA interface is...

Hi,

If you remove the Spindle Motor fan for cleaning, please also check the condition of PLG - Gear, Sensor & the Amp PCB for the PLG. Any oil dust deposit near it, can also create problem.

Hi,

Problem could be either the Indexing speed is slow or the PLC timer for timeout is set too low.

Which controller is this machine with & any idea of the drive / motor for turret. Is it 640...

Hi,

Thanks for sharing the information.
Will be really helpful for everyone here.

Hi,

What alarms do you get? We can try to analyse with details of alarms.

Also a I/O power supply failure can generate no. of alarms.

Hi,

Seems there is command for Magazine rotation, but no actual movement.

1) Magazine rotation is from Drive / Motor or Hydraulic? If Drive or Inverter / motor, which make Mitsubishi or Yaskawa...

Hi,

The Ladder display bit seems to be 0.

Please go to

1) Menu, PAR --> PLC --> BIT SELECT,

2) Set Par #6451 bit 0 = 1,
i.e. #6451 = xxxxxxx1, where x is old bit value.

Hi,

Machine Builders normally backup the ladder in the ROM. If it is backed up, you can find the file in F0 --> ROM Write menu. It will be easy to load from this menu.

If not available in this...

Hi,

I only changed settings for Y axis.

Could you try reducing the SV005 VGN for X-axis also? The value 300 looks too high & also the resonance gets enhanced with the higher value of VGN....

1. SV038: OK, I understand. Try 0 0 0. If it does not help, go back to factory setting.
If I test SV005 as well, shall I do that seaparately and after testing 0 0 0 with SV038?

You can try both...

Hi,

Do you have the PLC Ladder Manual? If so, try to find the L Parameter for chucking type selection INTERNAL & EXTERNAL.
If you get it, you can try forcing it in I/O Monitor screen.

Hi,

Reply as below,

1)Why do you want me to insert 0 0 0 for SV038?Why not just leave it with my present values: 165 150 150 ?

It was only to check, if the vibration is due to wrong value....

Hi,

Sorry, in last reply i forgot to discuss about SV038 & Resonance. What i understand is, resonance frequency is a natural frequency of mechanical system & when it equals to that of current loop...

Hi CNC Viking,

If problem occurs after few hours, it seems to be some electronic component problem.

Is the encoder for Z-axis same? If so, could you try swapping it with X, to isolate the...
