Rockwell Automation LPM20 Liquid-Cooled AC Drive with High Performance Drive Control - Manual (Page 41)

Installation/Wiring 1-29
Figure 1.11 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 all
Digital Inputs is 24V. This must
be switched in order to use
115V.
Note:
Digital Inputs 1, 2, and 3 are
always 24V dc.
Sourcing Digital Inputs - using internal power supply Sourcing and Sinking Definitions
The digital inputs and digital outputs of the LPM20
with High Performance Drive Control 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
A. Connect the digital input common (return) directly
to the power supply common.
B. Applying positive voltage to the digital input will
cause it to activate (pull up).
Sourcing a Digital Output
A. Connect the digital output common (return)
directly to the power supply common.
B. Connect the device to be controlled by the digital
output to the positive voltage, and the device
common to the digital output.
Sinking a Digital Input
A. Connect the digital input common to the power
supply positive voltage.
B. Applying 0V or common to the digital input will
cause it to activate (pull down).
Sinking a Digital Output
A. Connect the digital output common (return) to the
power supply positive voltage.
B. Connect the digital output to the device to be
controlled, and the device common to the power
supply common.
Note:
Digital Inputs 1, 2, and 3 can only be configured as
sourcing inputs. Digital Inputs 4, 5, and 6 can be
configured as sourcing or sinking inputs.
