Step 13. Editing the S Code Function

When ACR-MOTIONMAX Encounters a SCode … Example: S2000.

It will do the following Steps.

1). Check if the Requested Spindle Speed is different from the Current Spindle Speed.

2). If it is it then checks if the Speed is within the current Gear Range as defined in the Parameters.

3). If the new Speed requires a different Gear, ACR-MOTIONMAX will set the Binary code of the Gear Range to be in.

4). If Gear Change is Required then the AcroBasic shall stop the spindle and switch to the new Gear Range.

5). If the spindle was previously running (SpindleRunning Bit 190 =1) then the function will restart the spindle and wait till its running at the commanded speed.

6). If the spindle wasn’t previously running (SpindleRunning Bit 190 =0) the function should write the Dac value but not restart the spindle.

7). The function then Clears the S Strobe and sets the S Done bits to Signal ACR-MOTIONMAX to continue.
