  • Page 4: Introduction

    EM542S Digital Stepper Drive User Manual 1. Introduction The EM542S 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.

  • Page 6: Elimination Of Heat

    EM542S Digital Stepper Drive User Manual 2.4 Elimination of Heat EM542S’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.

    EM542S Digital Stepper Drive User Manual 4. Control Signal and Fault Output 4.1 Control Signal Connection The EM542S 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.

    EM542S Digital Stepper Drive User Manual 5.3 8-lead Motor Connection EM542S 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.

    EM542S Digital Stepper Drive User Manual 6.2 Power Supply Sharing Multiple EM542S drives can share the same power supply, if that power supply has enough capacity. To avoid cross interference, connect each EM542S DIRECTLY to that shared power supply separately instead of connecting those power connectors of drives in daisy-chain connection.

    EM542S 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.
