Hi Tom, Bits: Of course, I meant 2 bits. Yes. Accuracy, a sample: Imagine an encoder with only three(!) points. At 0°, 120° and 240°. Further we take a stepper with only 4(!) steps. At 0°, 90°,180°,270° So, this seem for me not accurate. The encoders result and the steppers postion never match! It h...

Hi Tom I do not understand why it is irrelevant to have matching drivers. There is no microstepping on these drivers. So be it, your surely know. Thanks for the tip with the lower 4 bits! This makes it easier on the pin count. So, the 5 axis are easy with KFLOP. Last question: The drivers have diffe...

Ok, I just studied more... It seems not to be a clever idea to combine a 1024 pulse encoder with a 5-phase motor (500 steps per rev) because there is not a single point where they match. It is 0.35156° per step for the encoder and 0.72° for the stepper. Am I completely wrong? They sell them as indus...

Thanks for the reply, >Do you have detailed specifications on the encoders and Drivers? I attached some images. The encoder is a KOYO TRD-3A1024-2610. So it has 1024 positions per 360°. I have no manual,I assume the outputs are Open Collector type. The driver is from Vexta (CSD5807N-P) http://site.m...

Hello The KFlop board looks impressive. i would be happy to have some starting help. I'm planning a closed loop setup. My Encoders have a grey code output (10Bits, Open Collector). So I need for each stepper 10Bits/Pins. The advantage is, the position is clear at startup. My Motor driver has differe...
