DM556 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.
DM556 Digital Stepper Drive User Manual 1. Introduction The DM556 is a new digital stepper drive based on Leadshine’s widely implemented DM stepper drives (10+ millions of units in field). While retaining features of simple design, easy setup, high precision and reliability, Leadshine has also upgraded it by adopting the latest stepper control technology and added additional advanced features for better torque (10-25%), quicker response time, control command smoothing, easy self-test, etc.

DM556 Digital Stepper Drive User Manual 2.4 Elimination of Heat DM556’s working temperature is less than 60℃ (140°F) It is recommended to use automatic idle-current mode to reduce motor heating. That means set the SW4 pin of DIP switch at “OFF” position. It is recommended to mount the drive vertically to maximize heat sink area.
DM556 Digital Stepper Drive User Manual 3.2 P2 - Fault and Brake Output Connector Details Output Connection: Optional. (1) Maximum 30V/100mA output (2) Sinking or sourcing (3) The resistance between ALM and COM- is low impedance as default (configurable by DIP switch SW12), and will change to high when the drive goes into error protection.
DM556 Digital Stepper Drive User Manual 4. Control Signal and Fault Output 4.1 Control Signal Connection The DM556 can accept differential or single-ended control signals (pulse, direction, and enable) in open-collector or PNP connection through the P1 connector (figure 2). It is recommend to add an EMI line filter between the power supply and the drive to increase noise immunity for the drive in interference environments.

Stepper Motor Connections DM556 can drive 2-phase and 4-phase bipolar hybrid stepper motors with 4, 6, or 8 leads, Leadshine also offers easy-to-use and good-performance motors with 4-lead that have been tested with DM556: (http://www.leadshine.com/series.aspx?type=products&category=stepper-products&producttype=stepper-motors&subt ype=hybrid-stepper-motors&series=cm) 5.1 4-lead Motor Connection (recommended)
DM556 Digital Stepper Drive User Manual 5.3 8-lead Motor Connection DM556 can power 8-lead in series or parallel connection in series or parallel. Series connected 8-lead stepper motors are typically implemented in applications which higher torque at lower speed movement is required. Because a stepper motors under series connection has the most inductance, the performance will start to degrade when the motor runs at higher speed.
DM556 Digital Stepper Drive User Manual 6.2 Power Supply Sharing Multiple DM556 drives can share the same power supply, if that power supply has enough capacity. To avoid cross interference, connect each DM556 DIRECTLY to that shared power supply separately instead of connecting those power connectors of drives in daisy-chain connection.

DM556 Digital Stepper Drive User Manual 12. Troubleshooting In the event that your drive doesn’t operate properly, the first step is to identify whether the problem is electrical or mechanical in nature. The next step is to isolate the system component that is causing the problem. As part of this process you may have to disconnect the individual components that make up your system and verify that they operate independently.
