Chapter 1 Selection Considerations
Hardware Enable Circuits
The PowerFlex 700S drive digital input Di 6 can be programmed for any
available digital input functions, including hardware enable. The PowerFlex
700S drive has a hardware enable jumper (P22) on the main control board. See
Figure 9
to identify jumper (P22). By default, hardware enable is not used,
jumper (P22) is closed (connected to pins 1
…3), and Di 6 can be configured
for other uses. If hardware enable is used, jumper (P22) is open (connected to
pins 2
…4), requiring a hardware enable contact wired to Di 6. Parameter P830
[Dig In6 Sel] is not available when HW Enable is enabled (jumper (P22) is
open, on pins 2-4).
The PowerFlex 755T Main Control Board Port 0, Digital input Di 0 can be
configured for any available digital input functions, including DI ENABLE.
See Figure 11
to identify the ENABLE jumper (J7). By default hardware
enable is not used and jumper (ENABLE) is installed. If hardware enable is
used, ENABLE jumper (J7) is removed.
• If the Main Control Board Port 0, Di 0 will be used for the hardware
enable input, verify that parameter 0:103 [DI M Enable] is set =
0:100.00 [Digital In Sts].
• If it is desired to use the same Port 0, Di 0 input for the line side
converter enable, 0:105 [DI L Enable] is set = 0:100.00 [Digital In Sts].
This setting is not applicable to PowerFlex 755TM common bus
inverters.

Comparison
This section compares customer power terminals of the PowerFlex 700S
frames 9…14 drives and PowerFlex 755TL/TR drives and PowerFlex 755TM
common bus inverters frames 8…12.

TIP If desired, a digital input on an installed I/O option module can be assigned
to the hardware ENABLE input by setting 0:103 [DI M Enable] and/or 0:105
[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.
