Selection Considerations Chapter 1
Hardware Enable Circuits
The PowerFlex 700AFE bus supply digital input 6 can be programmed for any
available digital input functions, including hardware enable. It has a hardware
enable jumper (J5) on the main control board (Figure 7 on page 51
). By
default, hardware enable is not used, jumper (J5) is installed, so digital input 6
can be configured for other uses. If hardware enable is used, jumper (J5) is
removed, which requires a hardware enable contact wired to Di 6. Verify that
parameter P226 [Digital In6 Sel] is set to ‘1’ (Enable).
The PowerFlex 755TM bus supply Main Control Board Port 0, Digital input
Di 0 can be configured for any available digital input functions, including DI
ENABLE. See Figure 8 on page 54
to identify the ENABLE jumper (J7). By
default, hardware enable is not used and the ENABLE jumper (J7) is installed.
If hardware enable is used, ENABLE jumper (J7) is removed.
If the Main Control Board Port 0, Di 0 is used for the hardware enable input,
verify that 0: P105 [DI L Enable] is set = 0: P100.0 [Digital In Sts].
TIP If desired, a digital input on an installed I/O option module can also be
assigned to the hardware ENABLE input by setting 0: P105 [DI L Enable] = to
the Port and digital input status parameter and bit on the I/O option module
that will be used as the hardware ENABLE.
