AC motor control DM2722 series

two-phase stepper

Mechanical Specification Descriptions The DM2722 is full digital 2 phase stepper driver based on DSP control. The drive voltage of which is from 110V to 230VAC. It is designed for use with the 2 phase hybrid stepper motor of all kinds with 86mm to 130mm outside diameter, regulated phase current 1.2A to 7.0A. The circuit that it adopts is similar to the circuit of servo control which enables the motor running smoothly without noise and vibration. The highest micro step is 60000ppr. It is widely used in middle and big size numerical control devices such as curving machine, CNC machine, computer embroider machine, packing machine etc. Features 1. 16 channels constant angle, constant torque micro steps, highest micro step: 40000ppr 2. Drive current is adjustable in 16 channels from 1.2A/phase to 7.0A/phase 3. Highest response frequency: 200Kpps 4. Current of winding will be reduced by approximately 50% when no step pulse command is received for 0.1 second 5. Opto-isolated signal I/O 6. Single power supply from 110V to 230VAC
