Communications
Pin Assignment - P1 Power, I/O and SPI
Connections
Pin # Function Description
Pin 1 N/C No Connect
Pin 2 N/C No Connect
Pin 3 Opto Reference
The Signal applied to the Optocoupler Reference will
determine the sinking/ or sourcing configuration of the inputs.
To set the inputs for sinking operation, a +5 to +24 VDC
supply is connected. If sourcing, the Reference is connected
to Ground.
Pin 4 Step Clock/Channel
A/ Clock Up
Step Clock input. The step clock input will receive the clock
pulses which will step the motor 1 step for each pulse. It
may also receive quadrature and clock up type inputs if so
configured.
Pin 5 Enable
Enable/Disable Input will enable or disable the driver output
to the motor. In the disconnected state the driver outputs are
enabled in either sinking or sourcing configuration.
Pin 6 Direction/Channel B/
Clock Down
Direction input. The axis direction will be with respect to the
state of the Direction Override Parameter. It may also receive
quadrature and clock up type inputs if so configured.
Pin 7 +5 VDC Output Supply voltage for the MD-CC300-000 Cable ONLY!
Pin 8 SPI Clock The Clock is driven by the SPI Master. The clock cycles once
for each data bit.
Pin 9 GND Communications Ground.
Pin 10 MISO Master-In/Slave-Out. Carries output data from the MFM back
to the SPI Master.
Pin 11 CS SPI Chip Select. This signal is used to turn communications
on multiple MFM units on or off.
Pin 12 MOSI Master-Out/Slave-In. Carries output data from the SPI Master
to the MFM.
