ST-28H 2-Phase stepper motor driver features
1. Using quadratic subdivision c?ntrol technology when at lowspeed,the motor resonance will decrease greatly;
2. Over current , over temperature inside to protect the circuit;
3. The largest driver peak current is 5.0 amps ,and there are 16files current to select;
4. No-over current, bipolar constant current chopper withtwenty, thousand times per second;
5.16 file subdivision is adjustable, the highest resolution is 51 200 steps/roll;
6. Single pulse and double pulse working mode is adjustable
7. Up to 200KHZ frequency response;
8. Phase power automatic memory function.
