Leadshine 3ND883 three-phase gear driver

Description

The 3ND883 is a high-resolution three-phase microstepping driver based on precision current control. It is suitable for driving NEMA size 17 to 34 three-phase hybrid stepper motors. Using advanced pure sine wave current technology, it makes stepper motors close to servo motors in smoothness and noise. Compared to the 3ND583, it has a wider supply voltage range and offers a larger microstepping range, due to which they can be used to replace more two-phase stepping systems directly without changing the software, offering better performance.

General characteristics:< br> High performance, low noise
Low motor heating
Supply voltage up to 80VDC
Output current up to 8.3A (RMS 5.9A)
Input signal TTL compatible
Auto reduction no-load
Suitable for 3-phase stepper motors, including 3/6 wire
Optically isolated differential input signals, pulse frequency up to 300 kHz
16 selectable resolutions up to 25600 steps/rev
DIP-current setting switch with 8 different values
modes PUL / DIR & CW / CCW optional
Overload, short voltage, over current, and over temperature protection
Small size for easy mounting

The driver is suitable for a wide range of NEMA 17 to 34 stepper motors. Used with various kinds of machine tools such as XY tables, engraving machines, labeling machines, laser cutting machines, transfer machines, etc. Extremely well suited for applications requiring low noise, low heat, high speed and accuracy.

Options

The driver uses an 8-bit DIP switch to set the microstep resolution and motor operating current:

&nbsp; SW 1 ┐ &nbsp; &nbsp; SW 2 ├─ Operating current &nbsp; SW 3 ┘ &nbsp; &nbsp; SW 4 ── Holding current (50%/100%) &nbsp; SW 5 ┐ &nbsp; &nbsp; SW 6 │ &nbsp; &nbsp; SW 7 ├─ Microstep resolution &nbsp; SW 8 ┘ &nbsp;

Setting the operating current, the first three DIP switches (SW1, 2, 3):

Peak current, A Effective current, A SW1 SW2 SW3 2.2 1.6 off off off 3.1 2.2 on off off 3.9 2.8 off on off 4.8 3.4 on on off 5.7 4.1 off off on 6.6 4.7 on off on 7.4 5.3 off on on 8.3 5.9 on on on

Setting the holding current with switch SW4.
In the OFF position, the holding current is set to 50% of the operating value,
in the ON position, it is set equal to the selected value of the operating current.

Microstep mode selection

is set by DIP switches SW5, 6, 7, 8 as shown in the table:

Steps/revolution for motor 1,2 SW5 SW6 SW7 SW8 200 on on on on 400 off on on on 1600 on off on on 3200 off off on on 6400 on on off on 12800 off on off on 25600 on off off on 500 off off off on 1000 on on on off 1200 off on on off 2000 on off on off 4000 off off on off 5000 on on off off 6000 off on off off 8000 on off off off 10000 off off off off
