* Note: indicated speeds are approximate and may vary with oscillator frequency and other factors.
Please verify exact value before using in any speed-critical application.
The following chart depicts revolutions per second for a 1.8 º stepper motor, in relation to the three
speed selection bits, for both full and half stepping. Please note that the speed increase is
nonlinear; i.e. finer speed control is available at slower step speeds. Again, indicated speeds are
approximate and will vary with oscillator frequency. Please verify exact value before using in any
speed-critical application.
