Is your port enabled under ports and pins? Is the port address correct?
To test the port go to config - ports & pins - Input signals - automated setup of inputs and trigger the inputs

Try using autocad or turbocad to draw the gasket or do as Graham says - give us the measurements.
It's that simple!

I am not so familiar with ABB products. Does your VFD have a comm port. Most VFD's have a RS485 port.
If it does - the check the manual to see if your VFD supports modbus.
The other option is to a modbus plc with an analog input card.

Does the VFD have modbus - If so I am sure you could do it.

Hi Shamus
OK lets begin at the beginning - make a simple drawing in autocad eg. a circle or square(or whatever drawing program you use) save it as a dxf.Now open mach. Go to file-lazycam. Once lazycam is open click on open DXF. You now have your drawing in lazycam. set the cut height an start height in the layers tab.click on post code.tick the relevant boxes and click OK. Now open mach and run your program.
Then I recommend that you read the wiki manual.

It depends on what you would like to us the drive for.
If you only require it for the spindle at close to synchronous speed then you can use a normal motor,
but if you are using it for a low rpm, high rpm or constant start/stop operation then it is better to use an inverter motor
which has seperate windings for the cooling fan or use an external cooling fan - at high rpm the motors fan will draw higher
current from the motor and may even stall the motor.

It should work. Most ac servo drives can be configured for step/direction, quadrature or analog inputs.
I use the delta servo drives. Check them out at www.delta.com.tw. They do have an agent in Europe.

Hi Graham

Thanks for the reply. Lets begin at the beginning.
How do I write the script for the M25.m1s file to execute 1 punch cycle?
