Rockwell Automation SF3000 Parallel Gate Amplifier System - Manual (Page 34)

5-8 Parallel Gate Amplifier
The other end of each cable has a fifteen-pin female D-shell connector that mates with
the faceplate connectors on the PGA Power Supply module. The forward gate signal
cable should be connected to Input A and the reverse gate signal cable to Input B.
Appendix F provides a list of the Power Supply module cables used with the PGA
system. Note that the Power Supply cable length must not exceed 3.7 m (12 ft).
Refer to the wiring diagrams supplied with your system for the connection instructions
specific to your installation.
5.6 Connecting the PGA Module to the Gate Coupling
Circuits
The cables that are required for connecting the PGA modules to the gate coupling
circuits are specific to your drive system. Each cable is supplied with a 15-pin male
D-shell connector on one end that mates with the PGA module’s faceplate connector.
The cable connectors are color-coded black for Output-A type PGA modules and gray
for Output-B type. The other end of the cable is supplied with either a Cannon™ round
connector plug (cable #612436 or #612567) or an Elco™ square connector plug
(cable #612434 or #612566) to mate with the connector on the DC Power Module.
If needed, a cable (#612435) with individual connectors for the six gate coupling
circuits on the Power Module can be supplied as well. This cable mates with the
connector plug on the end of cable #612436 (Output-A) or #612567 (Output-B).
Table 5.2 describes the gate signals that are transmitted via these cables. The
connector plug is shown in figure 5.5.
Appendix F provides a list of the PGA cables that can be supplied with the system.
Note that the total cable length from the PGA module to the gate coupling circuit must
not exceed 18.3 m (60 ft).
