Hi all

I have an SQT10M and apparently the Mitsubishi Spindle Controller board has a problem. I now have a decision to make but before I can I need to know the following; My current board is designated FR-SF-2-11KP-TC-BN408U 009 and I have available a new board designated FR-SF-2-11KP-BN408U 067. Are these two boards compatible please?

the desigination you gave is for the entire spindle drive.the internal boards will be the same between the two units though. what kind of problem do you have on the spindle?

[Ambermile]

Hi, well yes I realise that and it's a big beastie too! Having spoken to Mazak it is their opinion that either the complete drive or maybe just the SF-CA PCB. The errors I am getting are as follows:

On the Monitor I am getting:

23 - Illegal Memory Servo
204 - Spindle Controller Malfunction Machine
128 - Emergency Stop NC

On the FR-SF board I am getting:

A.L0 12


and on the board above the FR-SF board (axis drives?) I get

Alternately F1 56 and F2 56


The price Mazak want is sort of scarey though!!

alarm 12 is a memory error on the sf-ca card.
you just need to swap the card itself, make sure to change the software chips,the eeprom chip and set the jumpers the same way as the original card and you should be good to go.
if any questions on this feel free to ask

[Ambermile]

Well, Mazak want £1731 exchange for the SF-CA board and I can get the complete FR-SF assembly for less than that?

I really am not sure what to do here... maybe just ge the machine up again and sell it!


Arthur

[kevins75]

here is a diagram of the board, the eproms and eeprom are the chips that need to be swapped.

[Ambermile]

Ah - that's an FR-SF Checking and adjustment procedure...

Arthur

PS - seem to have lost a post here?

[kevins75]

hopefully right file

[Ambermile]

Thanks for that, any ideas what would cause this to happen? The machine was not used for maybe three weeks and next turn on gave this error?

Arthur

[kevins75]

did you check the parameters on the drive to see if scrambled?

[Ambermile]

OK - I have not been able to move any further on this until yesterday when I turned the machine on and all was fine!! I left it on for a couple of hours then shut down and went home. Today, it's gone again! I have re-seated all the plugs on the SF-CAA board and also removed/re-inserted the EPROM chips and still no different - got the original three red alarms again and cannot get rid of them! Clearly I have an intermittent fault which wuld point to either a dry solder joint or a dodgy plug connection... I *really* don't want to have to buy a new board just to clear this problem, any more ideas?

try tapping on the top of the caa card and watch the 7 segment display to see if it flickers between different conditions.

I have several of these SE drives on machines.One of them threw a 12 alarm after it had been sitting unused for a while.It would not let me re-enter the parameters but would reset to the default parameters.This meant that when you programme an M05 the spindle would cost to a halt rather than wind down under power.We overcome this by programming S5 before the M05 and it winds down to 5rpm before coasting to a halt.Better than the £3K I was quoted for a board.
