 | | Re: 600 mA Limit
|
| The 600 milliamp limit is per channel, but for a given motor, two channels are wired in series. So you don't get 1200 milliamps per motor but only 600. This would still yield 1200 milliamps per chip, since there are drivers for two motors. Also, if (...) (29 years ago, 28-Mar-96, to lugnet.robotics.handyboard)

|
| I just realized that getting 1200 milliamps running two motors bi-directionally is equivalent to running four motors uni-directionally at 2400 from a total power dissipation standpoint. I.e., there are still 600 milliamps running through each (...) (29 years ago, 28-Mar-96, to lugnet.robotics.handyboard)

|
| The Miniboard manual says that it can vary the motor speed at 16 levels at either direction. It was mentioned earlier that the Handyboard can vary only 8. Is this correct? I'm seeing that the Miniboard motor drivers has a higher resolution than the (...) (29 years ago, 28-Mar-96, to lugnet.robotics.handyboard)

| (...) You mean running FOUR motors uni-directionally from ONE L293D chip, right? ...and TWO motors bi-directionally from ONE L293D chip? (29 years ago, 28-Mar-96, to lugnet.robotics.handyboard)

| it is only a difference in software. The Handy Board software does eight levels; the mini board software---which is different---does 16. -Fred -- This message was composed using Articulate Systems' PowerSecretary, a Macintosh-based speech-to-text (...)
