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

PUL+(+5V) |
Pulse signal: In single pulse (pulse/direction) mode, this input represents pulse signal, effective for each rising edge or falling edge (set by inside jumper J1); 4-5V when PUL-HIGH, 0-0.5V when PUL-LOW. In double pulse mode (pulse/pulse) this input represents clockwise (CW) pulse. For reliable response, pulse width should be longer than 1.5μs. Series connect resistors for current-limiting when +12V or +24V used. |
|
PUL-(PUL) |
|
|
DIR+(+5V) |
DIR signal: In single-pulse mode, this signal has low/high voltage levels, representing two directions of motor rotation; in double-pulse mode (set by inside J1 jumper), this signal is counter-clock (CCW) pulse, effective for low level. For reliable motion response, DIR signal should be ahead of PUL signal by 5μs at least. 4-5V when DIR-HIGH, 0-0.5V when DIR-LOW. |
|
DIR-(DIR) |
|
| ENA+(+5V) | Enable signal: This signal is used for enabling/disabling the driver. High level (NPN control signal, PNP and Differential control signals are on the contrary, namely Low level for enabling.) for enabling the driver and low level for disabling the driver. Usually left UNCONNECTED (ENABLED). |

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.
