Protections for over-voltage and over-current 1.2 Applications The DM556T stepper drive are designed to power 2 phase (1.8°) or 4-phase (0.9°) NEMA 23, 24, and 34 hybrid stepper motors. It can be easily adopted in many industries (CNC, medical, automation, packaging…), such as X-Y tables, engraving machines, labeling machines, mills, plasma, laser cutters, pick and place devices, and so on. -

3. Connection Pin Assignments and LED Indication The DM556T has two connector blocks P1&P2 (see above picture). P1 is for control signals connections, and P2 is for power and motor connections. The following tables are brief descriptions of the two connectors. More detailed descriptions of the pins and related issues are presented in section 4, 5, 9. -
Page 6: Led Light Indication
3.3 LED Light Indication There are two LED lights for DM556T. The GREEN one is the power indicator which will be always on generally. The RED one is a protection indicator which will flash 1-2 times in a 3-second period, when protection enabled for a DM556T. -
Page 7: Half Coil Configuration
Digital Stepper Drive DM556T 5.2.1 Half Coil Configuration As previously stated, the half coil configuration uses 50% of the motor phase windings. This gives lower inductance, hence, lower torque output. Like the parallel connection of 8 lead motor, the torque output will be more stable at higher speeds. -

Figure 8: 8-lead motor parallel connections 6. Power Supply Selection The DM556T can power medium and small size stepping motors (frame size from NEMA23 to 34). To get good driving performances, it is important to select supply voltage and output current properly. Generally speaking, supply voltage determines the high speed performance of the motor, while output current determines the output torque of the driven motor (particularly at lower speed). -
Page 9: Dip Switch Configurations
Digital Stepper Drive DM556T +24 - +48 VDC, leaving room for power line voltage fluctuation and back-EMF. Higher supply voltage can increase motor torque at higher speeds, thus helpful for avoiding losing steps. However, higher voltage may cause bigger motor vibration at lower speed, and it may also cause over-voltage protection or even drive damage. -

The current automatically reduced to 50% of the selected dynamic current 0.4 second after the last pulse. 7.3 Automatic Motor Matching & Self Configuration When powered on a DM556T will automatically configure itself with the best settings to match the driven stepper motor for optimal performance. No action is needed. -

Digital Stepper Drive DM556T Time(s) of Priority Sequence wave of red LED Description Blink Over-current protection activated when peak current exceeds the limit. Over-voltage protection activated when drive working voltage is greater than 60VDC Reserved. When above protections are active, the motor shaft will be free or the red LED blinks. Reset the drive by repowering it to make it function properly after removing above problems. -
