Pin Assignment - P1 I/O, SPI and Encoder

Connections

Pin #	Function	Description
		The signal applied to the Optocoupler Reference will
		determine the sinking/ or sourcing configuration of the inputs.
Pin 1	Opto Reference	To set the inputs for sinking operation, a +5 to +24 VDC
		supply is connected. If sourcing, the Reference is connected
		to Ground.
		Enable/Disable Input will enable or disable the driver output
Pin 2	Enable	to the motor. In the disconnected state the driver outputs are
		enabled in either sinking or sourcing configuration.
Pin 3	Index +	Encoder Index + Output.
Pin 4	Channel B +	Encoder Channel B + Output.
Pin 5	Channel B –	Encoder Channel B – Output.
Pin 6	N/C	No Connect.
Pin 7	Channel A +	Encoder Channel A + Output.
Pin 8	MOSI	Master-Out/Slave-In. Carries output data from the SPI Master
Pin 9	CS	SPI Chip Select. This signal is used to turn communications
		on multiple MDM units on or off.
Pin 10	+5 VDC Output	Supply voltage for the MD-CC300-000 Cable ONLY!
Pin 11	GND	Communications Ground.
Pin 12	N/C	No Connect.
	Direction/Channel B/	Direction input. The axis direction will be with respect to the
Pin 13		state of the Direction Override Parameter. It may also receive
	Clock Down
		quadrature and clock up type inputs if so configured.
Pin 14	Index –	Encoder Index – Output.
Pin 15	Channel A –	Encoder Channel A – Output.
Pin 16	SPI Clock	The Clock is driven by the SPI Master. The clock cycles once
		for each data bit.
Pin 17	MISO	Master-In/Slave-Out. Carries output data from the MDM back
		to the SPI Master.
		Step Clock input. The step clock input will receive the clock
Pin 18	Step Clock/Channel A/	pulses which will step the motor 1 step for each pulse. It
	Clock Up	may also receive quadrature and clock up type inputs if so
		configured.
		Open-Drain pending Over-temperature and Over-temperature
		Fault. When device reaches the temperature specified by
Pin 19	Fault Output	the warning temperature the output will pulse at 1 second
		intervals. When in Over-temperature fault the output will be
		active continually.
