4-6 Control Wiring for PowerFlex 700S Drives with Phase II Control
I/O Wiring Examples
Table H TB2 Terminals — Digital 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
Digital Inputs is 24V. This
must be switched in
order to use 115V.
Sourcing Digital Inputs - Internal Power Supply 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 will
cause 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 will
cause 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.
