DESCRIPTION

 

 

Introduction:

The 3ND883 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 3ND583, it has broader supply voltage range and offers more microstep resolutions, thus can be used to replace more 2-phase stepping systems directly without changing application software, offering better performances. And compared to most of the microstepping drivers in the market, both driver heating and motor heating have been reduced by 15-30%. 

Features:

THigh performance, low noise and lost cost

Low driver heating and low motor heating

Supply voltage up to 80 VDC

Output current up to 8.3A (RMS 5.9A)

Input signal TTL compatible

Automatic idle-current reduction

Suitable for 3-phase stepping motors, including 3 lead and 6 lead motors

Optically isolated differential input signals, pulse frequency up to 300 KHz

16 selectable resolutions up to 25600 steps/rev

DIP switch current setting with 8 different values

PUL/DIR & CW/CCW modes optional

Over-voltage, short-voltage, over-current and short-circuit protection

Small size for easy mounting

    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 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).

    Selecting Microstep Resolution and Drive Output Current

     

     

     

    The 3ND883 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:
