Digital 2 Phase Stepper Motor Driver DQ245M

DQ245M is 2-phase stepper motor driver based on advanced DSP control. It is new fully digital driver configured by DSP control chip and unique circuit. The driving voltage is DC24V-50V, adapting to all models of 2-phase hybrid stepper motor whose current is below 4.0A and with 42-57mm outer diameter. The internal driver circuit is similar to that of servo control, which makes the motor run smoothly, almost no vibration and noise. The max positioning accuracy can be up to 40,000 steps/R. It is widely applied in medium/small NC equipment with high resolution like engraving machines, small CNC machine, 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 stepper pulse stops over 100ms. 5)Optical isolating signals I/O6)Driving current can be adjusted from 1.2A/phase to 4.0A/phase through the 16 channels. 7)Single power supply (Voltage range: DC24V-50V)8)Phase memory function (Note: The driver can memorize the motor phase automatically when the input stops over 3 seconds. And also it 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. Nearly no vibration at low speed.
