Three Phase Stepper Drive

SM3MD2207

The SM3MD2207 is full digital 3 phase stepper driver based on DSP control. As a new generation of digital stepper motor drives, it is combined the advanced DSP control chip with the three-phase inverter driver module . The drive voltage of which is from 160V to 230VAC.It is designed for using with the 3 phase hybrid stepper motor of all kinds with 0.57mm to 130mm outside diameter, regulated phase current from 1.3A to 7.0A. The circuit that it adopts is similar to the circuit of servo control which enables the motor to run smoothly without noise and vibration. Moreover, its torque is far greater than 2 and 5 phase hybrid stepping motors. Furthermore, the highest micro step is 60000ppr. Due to these obvious advantages, it is widely used in middle and big size numerical control devices such as curving machine, CNC machine, computer embroider machine, packing machine and etc.

Description

6 channels constant angle, constant torque micro steps, highest micro step: 60000ppr
Highest response frequency: 200Kpps
Current of winding will be reduced by approximately 50% when no step pulse command is received for 1.5 second
Opto-isolated signal I/O
Drive current is adjustable in 16 channels from 1.2A/phase to 5.8A/phase (for DVS3722: 1.3A/phase to 7.0A/phase)
Single power supply from 110V to 230VAC
Phase terminal memory function (motor phase terminal is memorized after input pulse train stopping 3s and it is recovered when stepper driver power on or signal MF changes from low level to high level)

CURRENT SETTING :

Stepper driver working current is set by DIP switches D1 to D4.
