Four sets of stepper control outputs are provided on two 9-pin female D-type connectors. The
stepper control outputs can operate at up to 3 MHz. The 9-pin D-type connectors provide 360°
shielding when using high step rates.
The signals from the NextMove PCI-2 are at TTL levels but are converted to 5 V differential
drive signals by a circuit board mounted on the breakout module. However, the outputs can
be connected directly to drives with single ended logic inputs by connecting only the positive
outputs (STEPx+, DIRx+) and GND to the drive. The complements (STEPx-, DIRx-) must be
left unconnected. The outputs may be programmed in Mint for the following functions:
H Step and direction for controlling stepper motor drives. The Mint WorkBench Axis Config
Wizard (or Mint CONFIG and AXISCHANNEL keywords) are used to assign stepper
channels to axes.
H Digital outputs for general purpose use. See the Mint keyword STEPPERIO for details.
The FREQ keyword can be used to directly control the output frequency - see the Mint help file.
4.5.5 Emulator connection
An 11-pin footprint on the rear of the card marked ‘ICE’ provides access to the processor for
boundary scan emulation. To connect the Texas Instruments emulator pod, a two row 12-pin
0.1 in pitch surface mount pin header with pin 8 missing must be fitted. The connections are
those specified by Texas Instruments. See the ‘MintMT Embedded Programming Guide’ for
details on emulator based system debugging.
