Hi,

what I said in previous post about input 12 was just an example. If for example tool is stuck in the spindle input 12 is not active. If tool is properly released from spindle input 12 is active. All I want to do is put this in the  m6start macro. So If tool is stuck in the spindle I want macro to stop and wait for input 12 to be active or cancel  m6 macro. The same I want to do when spindle is running I want not to do a toolchange, or when chuck is not properly closed to repeat tool clamp.

Hello,

All the sensors in the spindle are working fine also my macro and toolchange. All I want to do is to put those signals into the macro to prevent all I written In previous post to happen.

Hello,

I've tried the new firmware from Rufi and it looks a lot better than before. CDFF gain is 0..15 for IIR filter setting to smooth the output. High value will smooth more but the PID response will become slower. I have settled in smooth level 5. It works a lot better in voltage, torque and velocity mode.  I'm now trying to tune servo drives in velocity mode in which was previously impossible. If i'm not using smooth level (cdff) i get follow error right away and can't tune out, but with smooth level 5 I can get tuning a lot better.
Can somebody please help me understand PN17 parameter on page 37 on the manual of my servo drives and how do you properly set it.

Hello,

sorry for late answer. I have a brand new ELTE ATC spindle and tool holders came with spindle. Spindle already have sensors built in. If for an example tool is stuck in spindle I don't get signal in input12 (input 12 active - spindle chuck is open). I have noticed in my test runs of my home built cnc that in long or heavy cuts tool can stuck in spindle but I dont know why. That could be disaster if this hapens while is changing tools. My m6start macro is working good but it is not safe. I would like to put in my macro to wait or cancel tool change if the tool get stuck in spindle, or when spindle is running or when it's not properly closed to prevent start of the spindle.Thanks.

Peter

I'm using 2MHz dspmc and servos with 3000rpm so my max speed is 3000 devideed by 10 (planetary gearbox 10:1) is 300rpm of the pinion . So 300rpm * 133,33mm = 39999 mm/min max speed. 39999 mm/min devided by 60 is 666,65 mm/sec. 1mm is 750,018 counts. 750,018 * 666,65 mm/sec = 499999,5 counts per second (max). If my calculations are correct I'm using 4 times lower limit than max limit of dspmc. It looks like you have done calculations correct.

Is there any way to calculate this value?

I'm using 750W servo motors and 2500 quadrature encoders for X,Y and Z axis. So one revolution of the motor is 10.000 counts. I'm using planetary gearboxes with 10:1 reduction. This means one revolution of the pinion is 100.000 counts. One revolution of the pinion moves gantry 133,33mm.
