Calculate SQ param. Mazatrol T1 Masak QT20

[ante708]

Hello.
Just got a "new" lathe.
Parameters was lost due to a bad battery.
I have put in all parameters from the book.

I can write programs and run them. BUT I cannot get the chuck to move its jaws with the pedals. It´s a hydraulic chuck.
When I actuate the valves manually it moves fine. The valves does not get any voltage when i use the pedals.

I think the SQ parameter is wrong, but I have searched all over and cannot find a value that works. With 512 I can run programs fine. With some other values I get errors when pressing cyclestart.
I have tested most of theese combinations 1, 2, 4, 8, 16, 32, 64, 128, 256, 512, 1024, 2048, 4096, 8192, 16384, 32768

Can anyone help me?

With SQ 512 I can get the chuck to open with an M06 line, but not close.

The in/out switch on the back of the machine seems to be backwards, I have to have it on inside clamping to be able o start a program with the aws closed.
Footpedals still does not work.

Now I got M07 working, and it holds pressure. But still no footswitch....

Have you checked that the foot switch is actually working? Might be just a faulty switch or wiring may have been damaged in transit

Solved!
A friendly member sent over a parameterlist and SQ 18576 was the right one for me.
