3.6 Status LED Lights There are two LED lights for EM422S. 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. -

Figure 6 Sourcing output 5. Stepper Motor Connections EM422S can drive 2-phase and 4-phase bipolar hybrid stepper motors with 4, 6, or 8 wires, Leadshine also offers easy-to-use and good-performance motors with 4-lead that have been tested with EM422S: (http://www.leadshine.com/series.aspx?type=products&category=stepper-products&producttype=stepper-motors&subt ype=hybrid-stepper-motors&series=cm) -

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 EM422S’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 11 for how to connect an 8-lead stepper motor for parallel connection. -
Page 10: Power Supply Selection
6. Power Supply Selection EM422S is designed to power small size stepping motors (frame sizes NEMA 8 to 17) made by Leadshine or other motor manufacturers. To get optimal performances, it is important to select proper power supply type, voltage, and supply output current. -
Page 11: Micro Step Configuration (Sw4-6)
1.56A 7.2 Micro Step Configuration (SW4-6) Each EM422S has 8 micro step settings which can be configured through DIP switch SW4, SW5, SW6. See the following table for detail. When they are set to ON, ON, ON, the microstep can be set via Leadshine ProTuner. -
Page 12: 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 EM422S drives, separately connecting the drives to the power supply is ... -
Page 13: Protection Functions
11. Protection Functions EM422S 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”... -
Page 14: Troubleshooting
EM422S 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. -
