3DM580S 3-Phase Digital Stepper Drive User Manual Important Notice Read this manual carefully before any assembling and using. Incorrect handling of products in this manual can result in injury and damage to persons and machinery. Strictly adhere to the technical information regarding installation requirements.
3DM580S 3-Phase Digital Stepper Drive User Manual 1. Introduction The 3DM580S is Leadshine newest digital stepper drive based on an advanced control algorithm. 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.
Figure 2 Connectors, DIP switches, and LED locations The 3DM580S has 4 connectors P1, P2, P3 and P4, 2 DIP switches S1and S2. P1 is for control signal connections, P2 is for fault output, P3 is for power and motor connection, P4 is for fine tuning.
Motor phase W 3.3 P4 - Tuning Port 3DM580S has a tuning port with RS232 to modify the drive parameters, it’s only for tuning, not for equipment control because neither precision nor stability is sufficient. The interface definition is as follows: Figure 3 Tuning Port 3.4 Status LED (Protection Functions)
4.2 Fault Output Connection When over voltage or over current protection happens, 3DM580S red status LED light will blink and the impedance state between ALM+ and ALM- will change (from low to high or high to low depending on configuration) and can thus be detected.

5.1 Output Current (SW1-SW4) The 3DM580S has 8 output current settings which can be configured through DIP switch SW1, SW2, SW3 and SW4. For a given stepper motor, as normal setting the output current to 1.4 times of motor phase current, will make it output larger torque, but at the same time cause more heating for both the motor and drive.
5.2 Standstill Current Setting (SW5) The SW5 of an 3DM580S is used to set output current percentage when motor is standstill. Idle current percentage will be set to 50% at OFF position, and 90% at ON position. When the driven stepper motor is idle (no movement) for 0.4 second, the output current of 3DM580S will be automatically reduced to the configured percentage.
6. Power Supply Selection The 3DM580S can power small and medium size 3-phase stepper motors (frame size from NEMA17 to 34) from Leadshine or other motor manufacturers. To get good system performance, it is important to select proper supply voltage and output current.
6.2 Power Supply Sharing Multiple 3DM580S drives can share one power supply to save space and reduce cost, if that power supply has enough power capacity. To avoid cross interference, connect each stepper drive directly to the shared power supply separately. To avoid cross interference, DO NOT daisy-chain connect the power supply input pins of the Drivers.
7. Motor Selection The 3DM580S can be used to drive 3- or 6-wire three-phase hybrid stepper motors with a step angle of 1.2 degrees. The choice of motor is mainly determined by the motor torque and current rating. The torque size is mainly determined by the size of the motor.
Twelve Month Warranty Leadshine Technology Co., Ltd. warrants its products against defects in materials and workmanship for a period of 12 months from shipment out of factory. During the warranty period, Leadshine will either, at its option, repair or replace products which proved to be defective.
