The next thing to configure is the axis settings including scale factors and user units.
Click on ‘Axis 1’ and then select the Settings tab from the window on the right. Select the user units required, the default is mm,
mm/s, etc. Next expand ‘Axis 1’ by clicking on the + symbol and click on ‘Axis 1_Enc’, then select the Parameter tab in the window
on the right. This is shown below:
Enter the correct scale factor for your axis. For example if you have a 2,500 line (10,000 counts/rev) encoder on your motor
connected to a 5:1 gearbox with a pulley on the output that moves a conveyor 200mm for one rev of the pulley your scale factor will
be:
200 mm /
//
/ (5 x 10,000 cts/rev) = 0.004 mm/count (or mm/INC)
Also on this same screen you need to set Encoder Sub Mask (absolute range maximum value) to 0xFFFFFFFF. This tells TwinCAT
that the MicroFlex e150 drive can handle 32bit absolute positioning.
