PowerFlex 700S Adjustable Frequency AC Drive - Phase II Control
Table 28 - TB2 Digital Input/Output Wiring Examples
Input/Output
Connection Example
Digital Inputs used for enable and
precharge control.
Note: 24V DC supply - supports only on-board
digital inputs. Do not use for circuits outside the
drive.
Note: The factory default for all digital inputs is
24V DC.
To use 115V AC on digital inputs 4…6 see
on page
Note: Digital inputs 1…3 are always 12V DC or
24V DC.

Sourcing and Sinking Definitions
The digital inputs and digital outputs of the PowerFlex 700S AC drive
support Sourcing or Sinking configuration. Typically, digital inputs
are sourcing devices and digital outputs are sinking devices. The
following definitions apply throughout this section:
• Sourcing a Digital Input - The digital input common (return) is
connected to the power supply common. Applying a positive
voltage to the digital input causes it to activate (pull up).
• Sinking a Digital Input - The digital input common (return) is
connected to the power supply positive voltage. Applying 0V or
common to the digital input causes it to activate (pull down).
• Sourcing a Digital Output - The digital output common
(return) is connected to the power supply common. The device to
be controlled by the digital output is connect to the positive
voltage and the device common is connected to the digital
output.
• Sinking a Digital Output - The digital output common (return)
is connected to the power supply positive voltage. The digital
output is connect to the device to be controlled and the device
common is connected to the power supply common.
Note: Digital inputs 1…3 can only be configured as sourcing inputs.
Digital inputs 4…6 can be configured as sourcing or sinking inputs.
