Page 5: Introduction,Features And Applications
1. Introduction,Features and Applications Introduction The M542H is an economical microstepping driver based on patented technology of Sunwind. It is suitable for driving 2-phase and 4-phase hybrid stepping motors. By using the advanced bipolar constant-current chopping technique, it can output more speed and torque from the same motor,compared with traditional drivers, such as L/R drivers.
Page 6: Specifications And Operating Environment
Sunwind Electronics Company Ltd. Stepper Motor Driver:M542H machines, such as X-Y tables, labeling machines, laser cutters, engraving machines,pick-place devices, and so on. Particularly adapt to the applications desired with low vibration,high speed and high precision. 2.Specifications and Operating Environment Electrical Specifications(Tj=25°C)

Page 8: Pin Assignment And Description
Usually left UNCONNECTED (ENABLED). Single pulse and double pulses mode switch There are two jumpers inside the M542H specifically for switch Single pulse and double pulses mode,as shown in figure 2. Default setting is Single pulse mode.
Page 9: Connector P2 Configurations
The M542H can accept differential and single-ended input signals (including open-collector and PNP output). The M542H 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 10: Connecting The Motor
Figure 4: Connection to PNP signal (common-cathode) 5. Connecting the Motor The M542H driver can drive any 2-pahse and 4-pahse hybrid stepping motors. Connections to 4-lead Motors 4 lead motors are the least flexible but easiest to wire. Speed and torque will depend on winding inductance.
Page 11: Connections To 6-Lead Motors
Sunwind Electronics Company Ltd. Stepper Motor Driver:M542H 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.

Sunwind Electronics Company Ltd. Stepper Motor Driver:M542H Figure 7: 6-lead motor full coil (higher torque) connections Connections to 8-lead Motors 8 lead motors offer a high degree of flexibility to the system designer in that they may be connected in series or parallel, thus satisfying a wide range of applications.

Figure 9: 8-lead motor parallel connections 6. Power supply Selection The M542H can match medium and small size stepping motors (from Nema size 17 to 34) made by Sunwind or other motor manufactures around the world. To achieve good driving performances, it is important to select supply voltage and output current properly.
Page 14: Multiple Drivers
To avoid cross interference, DO NOT daisy-chain the power supply input pins of the drivers. (Instead, please connect them to power supply separately.) Attention: NEVER connect power and ground in the wrong direction, as it will damage the M542H. Selecting Supply Voltage The power MOSFETS inside the M542H can actually operate within +20V－+100VDC, max...
