3 Phase Digital stepper controller 3DM683 (V2)

The 3DM683 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.

Compared to the 3ND583, broader input voltage and output current ranges make the 3DM683 can drive much more motors than the 3ND583, also smaller motor noise, lower heating.

• Extra-low motor noise offers excellent quietness
• Anti-Resonance, provides optimum torque and nulls mid-range instability
• Self-test and Auto-configuration technology, offers optimum responses with different motors
• Microstep resolutions programmable, from full-step to 102,400 steps/rev  
• Supply voltage up to +60 VDC  
• Output current programmable, from 0.5A to 8.3A 
• Pulse input frequency up to 200 KHz  
• Automatic idle-current reduction 
• Supports PUL/DIR and CW/CCW modes
• Suitable for 3/6 leads 3-phase motors

The 3DM683 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 SW5, 6, 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.
