01:51 PM s34n_: I have some questions about motor control strategy
01:52 PM s34n_: Lets say I have a univeral motor that can do 1000 rpm
01:53 PM s34n_: but I want to adjust the speed depending on feed rate of some external input
01:56 PM s34n_: so if the external feeder can feed 1000 widgets/min, the motor can run 100% to match 1 rotation/widget
01:57 PM s34n_: but if the external feeder only feeds 600 widgets/min, I want to adjust my motor.
01:57 PM s34n_: As the external feeder is constantly adjusting its rate, I also need to adjust
02:00 PM marder: hoi
02:01 PM marder: no
02:02 PM marder: adjust only if the geber has endpoint
02:02 PM s34n_: So I've considere two simple aproaches. I could trying to shape the motor curve to match the rate of the external feeder. Or, knowing that widgets are spaced every 1mm on the external meter, I could detect 1mm of travel, then run my motor 100% for 1ms
02:02 PM s34n_: *1mm on the external feeder
02:03 PM marder: der geber ist auf der gleichen acshe?
02:04 PM s34n_: so I guess the question is, should I shape the motor wave? or should I run the motor at 0 or 100% intermittently?
02:06 PM s34n_: marder: is that question for me?
