Leadshine 3DM683 Digital Stepper Drive work parameter 60 VDC 0.5A to 8.3A

Introduction

The 3DM683 is a versatility fully digital stepping driver based on a DSP with advanced control algorithm. The 3DM683 is the next generation of digital stepping motor controls. 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 drivers in 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.

Features:

Applications

Suitable for a wide range of stepping motors, from NEMA frame size 17 to 34. It can be used in various kinds of machines, such as laser cutters, laser markers, high precision X-Y tables, labeling machines, and so on. Its unique features make the 3DM683 an ideal solution for applications that require both low-speed smoothness and high speed performances.

Pin Function

Details

PUL+

Pulse signal: In single pulse (pulse/direction) mode, this input represents pulse signal, each rising or falling edge active (software configurable); 4-5V when PUL-HIGH, 0-0.5V when PUL-LOW. In double pulse mode (pulse/pulse) , this input represents clockwise (CW) pulse,active both at high level and low level (software configurable). For reliable response, pulse width should be longer than 2.5µs. Series connect resistors for current-limiting when +12V or +24V used. The same as DIR and ENA signals.

PUL-

DIR+

DIR signal: In single-pulse mode, this signal has low/high voltage levels, representing two directions of motor rotation; in double-pulse mode (software configurable), this signal is counter-clock (CCW) pulse,active both at high level and low level (software configurable). 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. Please note that rotation direction is also related to motor-drive wiring match. Exchanging the connection of two wires for a coil to the drive will reverse motion direction.

DIR-

ENA+

Enable signal: This signal is used for enabling/disabling the drive. High level (NPN control signal, PNP and Differential control signals are on the contrary, namely Low level for enabling.) for enabling the drive and low level for disabling the drive. Usually left UNCONNECTED (ENABLED).

Selecting Microstep Resolution and Drive Output Current

Microstep resolutions and output current are programmable, the former can be set from200 to 102,400 steps/rev and the latter can be set from 0.5A to 8.3A.

However, when it?s not in software configured mode, this drive uses an 8-bit DIP switch to set microstep resolution, and motor operating current, as shown below:

Microstep Resolution Selection

When it is not in software configured mode, microstep resolution is set by SW5, 6, 7, 8 of the DIP switch as shown in the following table:

Current Settings

When it?s not in software configured mode, the first three bits (SW1, 2, 3) of the DIP switch are used to set the dynamic current. Select a setting closest to your motor?s required current.
