Output table
The following table lists the outputs on connector J7:
Output
Pin
Number
Explanation
Step out and
step out
J7-1 and
J7-2
Outputs step signals for controlling external devices.
Sinks up to 24 mA.
Direction out
and direction
out
J7-3 and
J7-4
Outputs direction signals for controlling external
devices. Sinks up to 24 mA.
Enable
J7-5
Input to enable the 5345/5445 for operation. Connect
this input to the I/O Return to enable the 5345/5445.
I/O return
J7-6
Provides ground for the enable input and 5 V output.
+5 V dc
J7-7
Provides power for an external device. The maximum
allowable load on this pin must be an amount that,
when added to the load on pins J3-4 and J6-8, totals to
less than 450 mA.
Fault out
J7-8
This open collector NPN transistor output is ON (low)
if no fault and OFF (high) if fault.
No connect
J7-9
This pin is not used.
Mating
connector
The J7 discrete output cables are for a PCD 9-pin screw mating
connector. The connector , supplied with the unit, is ELFH09110.
Cable
requirements
Use 22- to 14-gauge wire for the cabling. Obtain cable for output
pairs (refer to table) twisted at about 3 to 4 turns per inch (1 to
1.5 turns per centimeter). As an option, the cable may be
shielded to reduce noise pickup.
CAUTION
To avoid ground loops, connect ground shield to user interface
only.
