4.5.5 Potentiometers
On board potentiometers are provided for setting the following motion pa-
rameters: Accel, Decel, Low Speed, and Run Speed. Run Speed can also
be set via:
a) external potentiometer, see Section 4.5.3.
b) external voltage input 0-5V or 0-10V, see Section 4.5.4.
This product is implemented using digital techniques. Micro-stepping at 1/32
step resolution (6400 pulses/revolution) is used to ensure smooth operation
at low speeds. The settings for Accel, Decel, Low Speed and Speed are
analog by nature and are converted to digital form using an 8-bit A/D. This
will result in granularity in the resolution settings. The ranges of each pa-
rameter are specified in Full Steps/sec. and Full steps/sec
