Micro-Step Stepper Motor Driver Hardware Manual Rev r0 FEATURES & SPECIFICATIONS Compatible with both Bipolar and Unipolar stepper motor User selectable to microstep function

Automatic reduction of current drive during hold state keeps your stepper motor running cool. Two modes of operation: Pulse Mode - Pulse input determines the speed and position.

1 Micro-Step Stepper Motor Driver Hardware Manual Rev r0 FEATURES & SPECIFICATIONS Compatible with both Bipolar and Unipolar stepper motor User selectable to microstep function significantly reduce motor vibrations for quiet and more reliable stepper motor operation. Automatic reduction of current drive during hold state keeps your stepper motor running cool. Two modes of operation: Pulse Mode - Pulse input determines the speed and position. Command mode - Just specify the speed and stop position, and the PWM driver does the rest for you. This includes acceleration and decceleration ramping. VM - Power Input 7-V Run & Holding Current Adjustor - for fast and easy motor revolu on adjustment. Copyright 0 Pages of 7 pages

The connected stepper motor s revolu on can be adjust by the stepper motor resolu on, the switch code is determined by 0 &, = UP and 0 = DOWN, the switch s resolu on code combina on is illustrated above (Figure.). The switch is also depending on JP X pin, if the X pin is Lo the stepper behavior is *. Note: When X pin is Hi stepper motor is half step and when it is in Lo state the stepper motor is at full step. The higher the stepper behavior is, the vibra on lessens and vice-versa the lower the stepper behavior is, the vibra on increases. Figure. Motor Connec on Port details. Table.
