Digital Outputs

The three digital outputs are dedicated to specific
functionality based on the Operation mode selected. For
example, Output 1 is used to control the contactor that
energizes and de-energizes the motor for a Direct (FVNR)
Motor application. In this example, Output 1 is used to
control the contactor and to protect the motor. It is a
normally open contact that closes when the active control
source instructs it to do so, provided there are no faults or
inhibits present. This same output contact opens when an
active protection instructs it to do so, to protect the motor. In
the case of the Direct Operation mode, only Output 1 is
dedicated to this mode, leaving Outputs 2 and 3 available as
general purpose relay outputs or another configurable
function. This is the case for each Operation mode selected.
Any of the three outputs not dedicated to an Operation mode
may be used as general purpose outputs, controlled by a
controller via a Fieldbus. Or, configured for another specific
purpose with the Power Xpert inControl Software Tool.
Any available outputs configured as general purpose outputs
are controlled by a controller via a fieldbus network such as
EtherNet/IP, PROFIBUS, Modbus TCP or Modbus serial. The
low 4 bits of the Field Output Control Word are used for this
purpose. Any of the four low bits, 0-3 can be assigned to
control any of the available outputs. In other words, bit 2 of
the Field Output Control Word could be assigned to control
output 2. But bit 0 could also be assigned as the control bit
for that output. The Power Xpert inControl Software Tool is
used to assign the bits in the Field Output Control word to
the available outputs.
There are 2 bits that are needed to control output 3 if the
C445 is ordered with the latching relay output option. Only
output 3 can be ordered as a latching relay output. The 2 bits
used for controlling output 3 when it is a latching relay are to
set and reset the output. If output 3 is not ordered as a
latching relay, then output 3 is controlled with one bit like
outputs 1 and 2. This is the reason there are four bits in the
Field Output Control word for controlling 3 outputs.
For more information on the Operation modes and
associated output wiring refer to System Configuration
Operation on Page 65.
All the available outputs not used for an Operation mode can
be configured as general purpose outputs or can also be
configured to indicate a specific Fault, Trip, Motor or Warning
status. The available outputs can be configured for specific
purposes using the Power Xpert inControl configuration
Software Tool or via Modbus commands. Refer to
Appendix D, for the Modbus Register map for C445 to
perform this configuration using a Modbus master. The
configuration Software Tool provides a user friendly way to
configure the outputs for the various selections.

Outputs dedicated to the selected Operation mode will be
shown as Reserved in the Software Tool when online with
the C445. Available Outputs will be shown configured as
None by default. The following functions can be selected for
each of the available outputs from the following list with the
Software Tool:
