-- Please see the file "StepperMotorWiring.bmp" for info on connecting 4 & 6 |
-- wire motors to your device. This source should drive either type, though connection |
-- to 4-wire motors requires significantly more FET's to buffer outputs. The |
-- circuitry for 6-wire motors is more straightforward. |
-- |
-- Another practical consideration is the threshold voltage of the FET's used to |
-- buffer the logic outputs & provide current drive to the motor. Most power |
-- FET's have a threshold voltage in the 5-12V range (or even higher), |
-- while logic devices now run in the 3.3V and lower range. Thus, you must be |
-- careful to choose a FET with a low threshold voltage, or a level-converter must |
-- be utilized between the logic output and the gate of the drive FET's. |
-- |
-- One of the most advantageous abilities of stepper motors is the ability to |
-- provide static holding force in any position. Of course this consumes power |
-- and heats the motor up significantly (though steppers are rated to handle this) |
-- use of the "static holding" input port will specify this behavior. |
