I try to find bldc parameters As bldc.pattern only needed with Halls, then only bldc.0.scale and bldc.0.poles remain? The motor pole pair pitch is 72 mm, and encoder is 200 pulses per mm. I set bldc.0.scale to 14400 and bldc.0.poles is 2 But still something's wrong. Also, there's a question about bldc init. I came up with init on Estop: net estop-out iocontrol.0.user-enable-out => bldc.0.init => hm2_7i43.0.3pwmgen.00.enable net x-is-init bldc.0.init-done => iocontrol.0.emc-enable-in => pid.x.enable It works, but after init is complete, motors power off, and power on when the machine is ON. Which is bad as they can loose the init position. How do I make it right?
