I have 4 300w p5 motors here, got them off ebay rather then the surpluscenter deal, and the encoder wires are 8 pin not 15. I assumed that this would be exactly the same as the surplus center ones, just with single ended outputs instead of differential.
From testing it looks like these motors don't have commutation signals, only differential encoder outputs.
Does anyone know how you get the back off these motors to get at the encoder? Its sealed so the back looks to be glued in place. Im hoping that its still got an encoder with commutation, and the wiring is all that has been changed. If not im totally screwed, as i cant afford to buy another set of drives to get around this.
motors are labelled p50b07030dcs50
also just to make sure, when im looking at commutation signals from drive they should be logic high for 1/3 of the rotation, and logic low for 2/3 right? |
