DriveTools SP Software
A software suite designed for running on various Microsoft Windows operating
systems. This software suite provides a family of tools, including DriveExecutive
software (version 3.01 or later), that you can use to program, monitor, control,
troubleshoot, and maintain Allen-Bradley products. DriveTools SP software,
version 1.01 or later, can be used with PowerFlex 750-Series, PowerFlex 7-Class,
and PowerFlex 4-Class drives, and also legacy drives that implement a SCANport
communication interface. Information about DriveTools SP software can be

Fault Action
A fault action determines how the option module and connected drive act when
a communication fault (for example, a disconnected cable) occurs or when the
controller is switched out of run mode. The former uses a communication fault
action, and the latter uses an idle fault action.
Fault Configuration
When communication is disrupted (for example, a cable is disconnected), the
option module and PowerFlex drive can respond with a user-defined fault
configuration. The user sets the data that is sent to the drive using specific fault
configuration parameters in the option module. When a fault action parameter is
set to use the fault configuration data and a fault occurs, the data from these
parameters is sent as the Logic Command, Reference, and/or Datalinks.
GSD (Generic Station Description)
File
A device database text file used by the network configuration tool to identify a
Profibus module and its capabilities. The file is normally registered in the
Profibus configuration tool for a device, and is supplied with the device via
removable media or on the internet as a download.
HIM (Human Interface Module)
A device that can be used to configure and control a drive. The PowerFlex 20-
HIM-A6 or 20-HIM-C6S HIM can be used to configure PowerFlex 750-Series
drives and their connected peripherals.
Hold Last
When communication is disrupted (for example, a cable is disconnected), the
option module and PowerFlex drive can respond by holding last. Hold last results
in the drive receiving the last data received via the network connection before the
disruption. If the drive was running and using the Reference from the option
module, it will continue to run at the same Reference.
Idle Action
An idle action determines how the option module and connected drive act when
the controller is switched out of run mode.
I/O Data
I/O data, sometimes called ‘implicit messages’ or ‘input/output’, is time-critical
data such as a Logic Command and Reference. The terms ‘input’ (To Net) and
‘output’ (From Net) are defined from the controller's point of view. Output is
produced by the controller and consumed by the option module. Input is
produced by the option module and consumed by the controller.
Logic Command/Logic Status
The Logic Command is used to control the PowerFlex 750-Series drive (for
example, start, stop, and direction). It consists of one 32-bit word of output to the
option module from the network. The definitions of the bits in this word are
shown in
