This auction is for One New 3ND883 3 Phase Analog Stepper Drive Available for immediate shipping from the US (not China) Features High 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 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%.

Electrical Specifications: Parameters 3ND883 Min Typical Max Unit Output current 2.1(1.5A RMS) - 8.3 (5.9 RMS) A Supply voltage 24 68 80 VDC Logic signal current 7 10 16 mA Pulse input frequency 0 - 300 kHz Isolation resistance 500 - - Mohm 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 1.5?s. 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 5?s 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). ENA-(ENA) Connector P2 Configurations Pin Function Details GND DC power ground. VDC DC power supply, (24~80)VDC, Including voltage fluctuation and EMF voltage. U Motor Phase U V Motor Phase V W Motor Phase W Current and Microstep settings: 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: Steps/rev.(for 1.2o motor) 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 Current Settings The first four bits (SW1, 2, 3, 4) of the DIP switch are used to set the dynamic current.
