2 этап Гибридный шаговый двигатель водителя DQ278M

DQ278M is 2 phase stepping motor driver based on DSP control. It is new fully digital driver configured by advanced DSP chip and unique control circuit. The driving voltage is DC24V-80Vand rated current is under 7.0A. The mating motor is 2 phase hybrid stepping motor with 57-86mmouter diameter. The internal driver circuit is similar to that of servo control theory, which makes the motor run smoothly, almost no vibration and noise. The max positioning accuracy can be up to 40,000 steps per revolution. DQ278Mis widely used in medium/small NC equipment with high resolution like engraving machines, small CNC machine tools, packaging machinery and etc.Features:1) High performance and competitive price2) 16-channel equal angle torque micro steps, max resolution 40,000 steps/R3) Max response frequency up to 200Kpps4) Coil current will be automatically reduced to 1/2 of pre-set current when stepping pulse stops over 100ms.5) Optical isolating signals I/O6) Driving current can be adjusted from 1.2A/phase to 7.0A/phase through the 16 channels.7) Single power supply (Voltage range: DC24V-80V)8)Phase memory function (Note: The driver can memorize the motor phase automatically when the input stops over 3 seconds. And it also can recover the phase automatically when it is re-powered or MF signals changes from low level to high level.)9) DQ series stepper motor drivers have different Algorithms for high and low speed, so motor runs more stablely and smoothly at highand low speed.
