IntroductionConstant angle, constant torque microstep driver supplies regulated phase current for supply voltage from 110V to 220V AC. It is designed for use with the 3-phase hybrid stepper motor of all kinds with 86mm to 110mm outside diameter and 5.2A current max. the circuit that it adopts is similar to the circuit of servo control in theory which enable the motor run smoothly at low speed nearly withour vibration and noise, output much greater torque at high speed than 2-phase and 5 phase hybrid stepper motor. The precision of location is up to 60,000 steps/rev. It is widely used in small-sized numerical control device such as medical machine, robot, instrumentation, curving machine, laser labeling machine, inner laser curving machine. Feature * High reliability, low price * 16 channels constant angle and constant torque, highest microstep up to 60000 steps/rev * Highest response frequency up to 200Kpps * Current of winding will be reduced to set value when no step pulse command is received for 0.1 second * Bipolar constant current chopping mode * Opto-isolated signal I/O * Driving current is adjustable from 0.6A/phase to 7.0A/phase devided into 16 channels * Single power supply from 110V to220VAC * Phase remembering function (The driver remembers motors phase when theres no input pulse is received for 5s and it recovers the motors phase when the power on or signal MF is inactive)
