* High performance, low price
* Highest response frequency: 200Kpps
* The motor phase current is reduced to set current value 100 ms after receiving the last pulse edge
* Bipolar constant current chopping circuit
* Opto-isolated input/output
* Driven current is adjustable continuously from 0.5A/phase to 8A/phase (0.4A/phase to 6.4A/phase)
* Single power supply, voltage arrange from DC 24/V to 80V (DC40V to 130V)
* Work as double 4 step or 4-phase 8 step
* Overvoltage protection, overheat protection, overcurrent protection

Q2HB88 (613) full / half stepper drive, driven voltage range from 24V to 80V (40V to 130V).
It can match 2-phase hybrid stepper motors whose rated under 8A (6A), shaft diameter range from 86mm to 110mm. It is widely used in numerical device such as curving machine, medium-sized numerical control machine, packing machine.
