SPI Connection and Interface
Connecting the SPI Interface
The SPI (Serial Peripheral Interface) is the
communications and configuration interface
for the MDriveAC Plus Microstepping inte-
grated motor/driver.
For prototyping we recommend the purchase
of the parameter setup cable MD-CC300-000
and adapter MD-ADP-M23 attach directly to
the MDriveAC Plus via a single-end Cordset..
For more information on cables and cordsets,
please see Appendix C: Cables and Cordsets.
SPI Signal Overview
+5 VDC (Output)
This output is a voltage supply for the setup cable only. It is not designed to power any external devices.
SPI Clock
The Clock is driven by the Master and regulates the flow of the data bits. The Master may transmit data at a
variety of baud rates. The Clock cycles once for each bit that is transferred.
Logic Ground
This is the ground for all Communications.
MISO (Master In/Slave Out)
Carries output data from the MDriveAC Plus Microstepping units back to the SPI Master. Only one
MDriveAC Plus can transmit data during any particular transfer.
CS (SPI Chip Select)
This signal is used to turn multiple MDriveAC Plus Microstepping units on or off.
MOSI (Master Out/Slave In)
Carries output data from the SPI Master to the MDriveAC Plus Microstepping.
