Hardware Enable Circuitry
Each main control board has one digital input, Digital Input 0, that can be used
as a general purpose programmable input, or by removal of a jumper,
configured as a dedicated hardware enable, which is unaffected by parameter
settings.
• PowerFlex 755T - Digital Input 0 is found on TB1
To configure Digital Input 0 as a dedicated hardware enable, complete the
following steps.
1. Access the control pod as described beginning on page 138
