Microstep Selection (SW1 Settings)
Switches 2, 3 and 4, of the DIP switch select the number of microsteps per step. The table below
shows the standard resolution values along with the associated positions for the select switches.
The standard waveforms are sinusoidal. Switch 1 selects the auto reduce current enable or dis-
able. With Switch 1 On, reduce current is enabled, with Switch 1 Off, reduced current is disabled.

Motor Selection
The DPC50501’s bipolar microstep driver is compatible with both bipolar and unipolar motor
configurations, (i.e. 8 and 4 lead motors, and 6 lead center tapped motors).
Step motors with low current ratings and high inductance will perform better at low speeds, pro-
viding higher low-end torque. Motors with high current ratings and low inductance will perform
better at higher speeds, providing more high-end torque.
Since the DPC50501 is constant current source, it is not necessary to use a motor that is rated
at the same voltage as the supply voltage. What is important is that the driver is set to the ap-
propriate current level based on the motor being used.
Anaheim Automation offers a comprehensive line of step motors in 17, 23, 34 and 42 frame
sizes. Contact the factory to verify motor/drive compatibility.
