2.5 Power Supply Connections

Figure 2.5: Power supply connections
In order to improve the anti-interference performances of the controller, the user can use two separate power
supplies for PUL/DIR control signals and I/O signals of the DMC5400. VDD1-GND1 or 5V-GND1 is the power
supply input ports for PUL/DIR control signals (5V-GND1 ports can be used as a power supply for customer use
when use VDD1-GND1), and VDD-EXGND is the power supply input ports for I/O signals. If I/O devices
generate little interference signal, then the user can use only one power supply for both PUL/DIR control signals
and I/O signals. If the user has one 12~24VDC and one 5VDC power supplies, then the 12~24VDC supply can be
connected to the VDD&EXGND ports and 5VDC supply can be connected to 5V&GND1 ports, while left VDD1
NOT CONNECTED (NC).
