• As you can see we have inserted these figu … As you can see we have inserted these figures into the drive shown in the picture above. Also take note that we have also set the command line to accept “Step/Direction in Positive Logic” and told the drive what output from the host controller to expect in this case “Open Collector Input” This now completes the RS Automation Drive setup.w completes the RS Automation Drive setup.  +
• Because we need an integer value (no Decim … Because we need an integer value (no Decimal values) we can change the 1^st Gear Ratio to allow this instead of a 1:2091.52 ratio which is not allowed in the software we change it to 100:2097152 to account for the 0.52 decimal. Therefore we calculate a ratio of these figures as and download them into the drive:- (see image)ures as and download them into the drive:- (see image)  +
• First we must tell the Drive a gearing bas … First we must tell the Drive a gearing based on the 100 count virtual encoder we have and actual motor encoder counts. In the picture above shows the drive with its motor connected which gives us an encoder count of 2097152 based on the motors encoder resolution which can be 17 bit or 21 bit etc.olution which can be 17 bit or 21 bit etc.  +
• If you want to convert the value to degree … If you want to convert the value to degrees then the calculation would simply be as in the image                                                Scale Factor = 1.1111 If we now commanded the motor to move 180 degrees the motor would rotate exactly half a turn.he motor would rotate exactly half a turn.  +
• Now if we command the motor to 5 mm it will rotate a 1 full turn of the motor and the lead screw. The picture shows the program setup.  +
• Our actual Stepper motors are 400 steps per revolution which is equivalent to an encoder quadrature count of 400/4 = 100.  +
• Take care of any physical gearboxes or gear trains you may have in your system these will need to be accounted for similar to the lead screw example  +
• The following description will be how to n … The following description will be how to now setup the Host controller (ESB-2). Assuming the “ScaleFactor” in the host controller is set to 1 if we commanded the motor to move 400 counts the motor will now complete 1 revolution. However 400 counts is an arbitrary figure so it needs converting into a “useful value” in this example we want to use millimetres therefore 1 revolution = 400 counts = pitch of a lead screw (5mm). To do this we need to set the “SCALEFACTOR” value in the mint controller software the calculation is as in the image, therefore Scale factor = 80.   
  ge, therefore Scale factor = 80.    <br/>  +
• We need to make a correlation between the 2 values of 100 counts that we want and the 2097152 of the actual motor drive system for the gearing ratio <br/>  +
