wonderwizard Posted April 7, 2015 Share Posted April 7, 2015 Hello, I have a Turbo PMAC LV driving a (Motor 1) Stepper Motor with high resolution linear encoder, and some inherited code. I am struggling to determine if the Author is trying to drive the stepper closed loop as a high pole count brushless motor? or as a direct micro stepped stepper. Reading around it looks like the Author might be trying to do a bit of both? In particular the following ref http://forums.deltatau.com/attachment.php?aid=179 seems to disagree with the motor protection bits in PLC 6. The axis (Motor 1) is a Sanyo 1.8 degree 2 phase stepper, driving a ball screw stage, the encoder is a linear tape type with quadrature outputs. It could well be that since the Geo Brick LV Setup Assistant now supports steppers as 'high count pole-pair brushless motors" then whatever way was being done could be improved? Although looking at the spreadsheet I am confused about if I should select stepper or brushless for Cell B13?

steve.milici Posted April 27, 2015 Share Posted April 27, 2015 You should select "Stepper" and let the "Setup Assistant" make the proper setting especially for the power on PLC. Link to comment Share on other sites More sharing options...
