Introduction?br />?/p>
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%.

Connector P1 Configurations
Pin Function | Details |
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), 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). |

Selecting Microstep Resolution and Drive Output Current
?/p>
The 3ND583 uses an 8-bit DIP switch to set motor dynamic current, standstill current and microstep resolution, as shown below:

Microstep Resolution Selection
?/p>
Microstep resolution is set by SW6, 7, 8 of the DIP switch as shown in the following table:
Steps/rev.(for 1.2o motor) | SW6 | SW7 | SW8 |
200 | on | on | on |
400 | off | on | on |
500 | on | off | on |
| 1000 | off | off | on |
| 2000 | on | on | off |
| 4000 | off | on | off |
| 5000 | on | off | off |
| 10000 | off | off | off |
Current Settings
?/p>
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.
Peak Current | RMS Current | SW1 | SW2 | SW3 | SW4 |
2.1A | 1.5A | off | off | off | off |
2.5A | 1.8A | on | off | off | off |
2.9A | 2.1A | off | on | off | off |
3.2A | 2.3A | on | on | off | off |
3.6A | 2.6A | off | off | on | off |
4.0A | 2.9A | on | off | on | off |
4.5A | 3.2A | off | on | on | off |
4.9A | 3.5A | on | on | on | off |
5.3A | 3.8A | off | off | off | on |
5.7A | 4.1A | on | off | off | on |
6.2A | 4.4A | off | on | off | on |
6.4A | 4.6A | on | on | off | on |
6.9A | 4.9A | off | off | on | on |
7.3A | 5.2A | on | off | on | on |
7.7A | 5.5A | off | on | on | on |
8.3A | 5.9A | on | on | on | on |
Note: Due to motor inductance, the actual current in the coil may be smaller than the dynamic current setting, particularly under high speed condition.
