X3 Digital Outputs

The control outputs are located on the X3 connector. A customer provided, external power supply must be used if digital outputs are to be used. The opto outputs provide status information and are not required for operation, Table 3-5.

Pin	Signal	Switch = Closed (active)	Switch = Open (not active)
Number	Name
X3-4	Fault +	Drive OK - no faults detected	Fault is detected
X3-5	Fault -	Drive OK - no faults detected	Fault is detected
X3-18	MAO1	Machine Output 1 = Logical 1	Machine Output 1 = Logical 0
X3-19	MAO2	Machine Output 2 = Logical 1	Machine Output 2 = Logical 0
X3-20	DrOK	Drive OK - no faults detected	Fault is detected

Fault Relay	A normally closed relay contact that opens if a fault occurs. The contact is rated:
	24VDC @ 0.8A maximum or 110VAC @ 0.3A maximum.
MaO1 & 2	Two machine outputs are provided. Either output can be set to one of the
	following conditions: CW Warning, CCW Warning, In Position, Error Flag,
	Following Error Warning, MAI1-2, Drive Overtemperature or I2T Warning.
	Each output is rated 30VDC @ 35mA maximum.
DrOK	This output is active when the control is ready for operation.
	This output is rated 30VDC @ 35mA maximum.
