3 Phase Stepper Controller

The 3DM583 is a versatility fully digital stepping driver based on a DSP with advanced control algorithm. It brings a unique level of system smoothness, providing optimum torque and nulls mid-range instability. Motor self-test and parameter auto-setup technology offers optimum responses with different motors and easy-to-use. The driven motors can run with much smaller noise, lower heating, smoother movement than most of the drives on the markets. Its unique features make the 3DM683 an ideal solution for applications that require low-speed smoothness.

The 3ND583 is a high resolution 3-phase microstepping driver based on precision current control technology. It’s suitable for driving 3-phase hybrid stepping motors from NEMA size 17 to 34. By using the advanced pure-sinusoidal current control technology, both the noise and vibration of the stepping motor have been greatly reduced, which makes the stepping motors offer servo-like performances. Compared to the 3MD560, it’s lighter and smaller, and compared to most of the microstepping drivers in the market, both driver heating and motor heating have been reduced by 15-30%.

Selecting Microstep Resolution and Drive Output Current

The 3ND583 uses an 8-bit DIP switch to set motor dynamic current, standstill current and microstep resolution, as shown below:

Microstep Resolution Selection

Microstep resolution is set by SW6, 7, 8 of the DIP switch as shown in the following table:

Current Settings

The first four bits (SW1, 2, 3, 4) of the DIP switch are used to set the dynamic current. Select a setting closest to your motor’s required current.

Note: Due to motor inductance, the actual current in the coil may be smaller than the dynamic current setting, particularly under high speed condition.
