Rockwell Automation 20D PowerFlex 700H and 700S Frame 9...14 Drives - Manual (Page 52)

52 Rockwell Automation Publication PFLEX-IN006E-EN-P - July 2013
Chapter 3 Control Wiring for PowerFlex 700S Drives with Phase II Control
Table 20 - TB2 Terminals - Digital Input Wiring Examples
Input/Output Connection Example Required Parameter Changes
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.
