4.5. Integrating the Gold Guitar on a PCB
The Gold Guitar is designed to be mounted on a PCB, either by soldering its pins directly to the
PCB or by using suitable socket connectors. Refer to the Gold Line Guitar Design Guide for
further information.
4.5.1. Grounds and Returns
The returns in each functional block are listed below:
Functional Block Return Pin
Power PR (Power Return)
Internal Switch Mode P.S. PR (Power Return)
Analog input return ANLRET (J2/20)
Common return COMRET (J2/25,31,32,43,46; J1/23)
STO safety signal return STO_RET (J1/10)
Input Return IN_RET (J1/3)
Table 8: Grounds and Returns
The returns above are all shorted within the Gold Guitar in a topology that results in optimum
performance.
Caution:
Follow these instructions to ensure safe and proper implementation. Failure to
meet any of the below-mentioned requirements can result in drive, controller
or host failure.
1. When wiring the traces of the above functions, on the Integration Board, the Returns of
each function must be wired separately to its designated terminal on the Gold Guitar. DO
NOT USE A COMMON GROUND PLANE. Shorting the commons on the Integration Board
may cause performance degradation (ground loops, etc.).
