bprall Posted January 11, 2022 Share Posted January 11, 2022 I am trying to setup two motors on these PWM drivers using the AX1313N. Neither motor type seems to be able to be configured by the wizard. The wizard does a terrible time with the Phase scaling calculation and seems to not use the brake properly. First motor is a linear motor with 3 cycles in 2 mm of travel with a linear encoder with 0.0001 mm resolution. It is a 3->1 UVW transition for the hall sensors. I hence set -170.6667 for AbsPhasePosSf. PhasePosSf is found to be about 0.0019999. This gives me good plots of UVW vs phase position when hand pushing the motor. This these settings it can get through the voltage 6 step test but fails out on the current loop. I know this motor works fine as I ran it with an ACS controller this morning to verify proper operation. Second motor is a rotary motor with 16 poles per rotation and 40,000 encoder counts. Also 3->1 UVW transition. PhasePosSf is on the order of 1.599e-5 to provide approximately close match between the phase cycles and the UVW when manually moving the motor. I will note that the units for this position are in REV compared to mm for the other motors and I have to use 4 million user units to get the proper alignment between revs and physical motion of the motor. This motor refuses to go through the 6 voltage step test. I have check that the motor resistances are correct and not shorted or broken.
