Functions and Operation

Outstanding feature
Using 32-bit DSP all digital control mode, advanced space vector algorithm to optimize low-vibrationand high-speed performance, and realize adaptive matching and optimizing control approach of avariety of motor, software update and easily upgrading.

Using micro-stepping algorithm to make the motor maintain optimal running performance whateverthe drive set which subdivision and greatly improve the smooth and noise under low subdivision. Evenif the user can not use the higher subdivision options due to the limit of control system output pulsefrequency , can also get both of low-speed stability and high-speed, thereby reducing therequirements of control system, and help to reduce the overall cost of the system to improve performance.

 Power Supply
The drive internal switching power supply design can adapt to a wide voltage range. Users canchoose 12V~40VDC depending on each situation. Capacity relates with the matching motor andsetting current magnitude. Generally the higher rated supply voltage is conducive to improvehigh-speed torque of the motor, but it will increase the loss and temperature of the drive. The powersupply must be noted the polarity, avoid reverse.

Micro-step selection
Users can select 16 kinds of micro-step models by the drive panel SW1, SW2, SW3, SW4 four dialswitch. It provides common two-phase step and five-phase step.
