Page 7: Pin Assignment And Description
3. Pin Assignment and Description The DM542 has two connectors, connector P1 for control signals connections, and connector P2 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 8: Connector P2 Configurations
4. Control Signal Connector (P1) Interface The DM542 can accept differential and single-ended inputs (including open-collector and PNP output). The DM542 has 3 optically isolated logic inputs which are located on connector P1 to accept line driver control signals. These inputs are isolated to minimize or eliminate electrical noises coupled onto the drive control signals. -
Page 9: Connections To 6-Lead Motors
DM542 Fully Digital Stepper Drive Manual V1.0 Connections to 6-lead Motors Like 8 lead stepping motors, 6 lead motors have two configurations available for high speed or high torque operation. The higher speed configuration, or half coil, is so described because it uses one half of the motor’s inductor windings. -
Page 10: Parallel Connections
6. Power Supply Selection The DM542 can match medium and small size stepping motors (from NEMA frame size 17 to 34) made by Leadshine or other motor manufactures around the world. To achieve good driving performances, it is important to select supply voltage and output current properly. -
Page 11: Selecting Supply Voltage
DM542 Fully Digital Stepper Drive Manual V1.0 Selecting Supply Voltage The power MOSFETS inside the DM542 can actually operate within +20 ~ +50VDC, including power input fluctuation and back EMF voltage generated by motor coils during motor shaft deceleration. Higher supply voltage can increase motor torque at higher speeds, thus helpful for avoiding losing steps. -
Page 12: Dynamic Current Setting
DM542 Fully Digital Stepper Drive Manual V1.0 connection methods. Phase current rating supplied by motor manufacturer is important in selecting driver current, however the selection also depends on leads and connections. The first three bits (SW1, 2, 3) of the DIP switch are used to set the dynamic current. Select a setting closest to your motor’s required current. -
Page 13: Wiring Notes
DM542 Fully Digital Stepper Drive Manual V1.0 8. Wiring Notes In order to improve anti-interference performance of the driver, it is recommended to use twisted pair shield cable. To prevent noise incurred in PUL/DIR signal, pulse/direction signal wires and motor wires should not be tied up together. -
Page 14: Sequence Chart Of Control Signals
DM542 Fully Digital Stepper Drive Manual V1.0 10. Sequence Chart of Control Signals In order to avoid some fault operations and deviations, PUL, DIR and ENA should abide by some rules, shown as following diagram: Figure 11: Sequence chart of control signals Remark: t1: ENA must be ahead of DIR by at least 5µs. -
Page 15: Frequently Asked Questions
DM542 Fully Digital Stepper Drive Manual V1.0 12. Frequently Asked Questions In the event that your driver 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. -
