TOPIC: Question on basic SmartMotor control

Question on basic SmartMotor control 1 year, 10 months ago #1670


I have what is hopefully a very basic SmartMotor control question. I have four SM23165DTs connected via Add-A-Motor cables in a standard daisy chain configuration. Communications with all motors are good. I'd like to have all four motors run in this fashion:

Start at position 0, velocity 0
Accelerate one-half shaft rotation (to position 2000), reaching some maximum velocity
Decelerate one-half shaft rotation (to position 4000), reaching velocity 0
Set origin to the current position (4000)
(Repeat forever)

The load on the shaft is minimal. Just getting started on this, so I do not know if Position Mode, Velocity Mode, or Torque Mode is best. Any help/suggestions/direction you can provide would be much appreciated!

Best regards,
Eric Alexander

Hi Eric,

This would best be done using Position Mode and Relative Position Moves. There is a section in the Support Download section called Developers Tools and Sample Programs. You will find a SmartMotor Developer Worksheet there that will help you calculate your Velocity and Accel/Decel values.
