Automatic idle-current reduction
Suitable for 2-phase and 4-phase motors
Soft-start with no "jump" when powered on
Over-voltage, over-curren protection
Anti-Resonance provides optimal torque and nulls mid-range instability
Pulse input frequency up to 200KHz, TTL compatible and optically isolated input
8 selectable peak current including 2.40A, 3.08A, 3.77A, 4.45A, 5.14A, 5.83A, 6.52A, 7.20A
Motor auto-identification and parameter auto-configuration technology, offers optimal responses with different motors
16 selectable microstep resolutions including 400, 800, 1600, 3200, 6400, 12800, 25600, 51200, 1000, 2000, 4000, 5000, 8000, 10000, 20000, 40000
Multi-Stepping allows a low resolution step input to produce a higher microstep output, thus offers smoother motor movement, works well as Cnc drive as well.
