    (10-25%), quicker response time, control command smoothing, easy self-test, etc. The EM556S stepper drive can power 2 phase (1.8°) and 4 phase (0.9°) stepper motors smoothly with very low motor heating & noise. It can take 20-50VDC supply voltage and output 0.5 to 5.6A current. All the micro step and output current configurations can be easily done via built in DIP switches.

    Connectors, DIP switches, and LED locations The EM556S has 5 connectors P1, P2, P3, P4 and P5, 3 DIP switches S1, S2 and S3. P1 is for control signal connections, P2 is for fault output, P3 is for power connection, P4 is for motor connection and P5 is for fine tuning.

    3.6 Status LED Lights There are two LED lights for EM556S. The GREEN one is the power indicator which should be always on in normal circumstance. The RED one is a drive status indication light, which will be OFF while working normally but ON and flash 1 or 2 times in a 3-second period in the case of enabled over-current or over-voltage protection.

  • Page 8: Control Signal And Fault Output

    Fault Output When over voltage or over current protection happens, EM556S red status LED light will blink and the impedance state between ALM and COM- will change (from low to high or high to low depending on configuration) and can thus be detected.

    Figure 7 Brake Output Connection 5. Stepper Motor Connections EM556S can drive 2-phase and 4-phase bipolar hybrid stepper motors with 4, 6, or 8 leads, Motion Control Products also offers easy-to-use and good-performance motors with 4-leads, ideal for running with the EM556S: https://www.motioncontrolproducts.com/electric-motors/stepper-motors/hybrid-stepper-motors/...

    Although setting the drive output current to 1.4 times of driven motor phase current will get the most torque, it is suggested to set an EM556S’s output current (peak of sinusoidal) to no more than 1.2 times the stepper motor’s phase current to prevent overheating. Refer to the figure 12 for how to connect an 8-lead stepper motor for parallel connection.

  • Page 11: Selecting Supply Voltage

    7.1 Output Current Configuration (SW1-3) The EM556S has 8 output current settings which can be configured through DIP switch SW1, SW2 and SW3. 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.

    EM556S will be automatically reduced to the configured percentage. 7.3 Micro Step Configuration (SW5-8) Each EM556S has 8 micro step settings which can be configured through DIP switch SW5, SW6, SW7 and SW8. See the following table for detail. When they are set to ON, ON, ON,ON, the microstep can be set via Leadshine ProTuner.

  • Page 13: No Auto Tuning Configuration (Sw11)

    7.5 No Auto Tuning Configuration (SW11) EM556S can configure itself with the best match to the driven stepper motor. This feature may need to be disabled for some applications or when it is used to drive a specially designed stepper motor. To do that, set the DIP switch SW11 to ON position and the drive will be set to its default settings.

  • Page 14: Wiring Notes

    It is better to separate them by at least 10 cm; otherwise the disturbing signals generated by motor will easily disturb pulse direction signals, causing motor position error, system instability and other failures. ⚫ If only one power supply serves multiple EM556S drives, separately connecting the drives to the power supply is recommended instead of daisy-chaining. ⚫...

  • Page 15: Protection Functions

    11. Protection Functions EM556S incorporates are built with over-voltage and over-current error protections. When it is under error protection, the red LED light will blink for 1 or 2 or 4 times in a period of 3 seconds. If fault output connection is connected, the impedance mode between ALM+ and ALM- will be changed (See “Fault Output Configuration”...

    EM556S 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.
