Size and shape




Performance introduction:

1 the AC servo control principle control mode increases the digital current loop control, three-phase sinusoidal current drive output, the three-phase hybrid motor in low speed without crawling, undocumented East, low noise

2 drive voltage amplifier level reached DC325 volts, the stepper motor is still running to tell high torque output

3 with short circuit overvoltage, undervoltage overheating protection function, high reliability


4 segments and semi flow function, there are a variety of options can be set to the minimum step angle of 0.036 degrees
