Glossary of Terms
ToolSuite - Is the suite of programs developed by Siemens that allows easier access to the NXG drive for
A
programming and monitoring. It is comprised of the following components:
•
ToolSuite Launcher - also referred to as ToolSuite; used for coordinating other tools.
•
SOP Utilities - used to launch an editor that compiles or reverse compiles a System Program. It also allows
for serial connection to the drive for uploading and downloading System Programs.
•
Configuration Update - allows for backing-up, updating, and cloning drives via direct access to the Flash
Disk.
•
Host Simulator - used for monitoring, programming, and controlling a drive remotely from a PC over the
built-in ethernet port of the drive. Parameter changes, status display, and graphing of internal variables are
its main functions.
•
Debug Tool - this tool is used to display the diagnostic screens of the drive for diagnosing drive problems or
improving performance via the built-in ethernet port of the drive.
ToolSuite Launcher - see ToolSuite definition.
Torque - The force that produces (or attempts to produce) rotation, as in the case of a motor.
Uploading - Uploading is a process by which information is transmitted from the drive to a remote device such as a
PC. The term uploading implies the transmission of an entire file of information (e.g., the system program) rather
than continued interactive communications between the two devices. The use of a PC for uploading requires
communications software to be available on the PC.
Variable frequency drive (VFD) - A VFD is a device that takes a fixed voltage and fixed frequency AC input source
and converts it to a variable voltage, variable frequency output that can control the speed of an AC motor.
Vector control - Vector control is one of two available application modes of the Perfect Harmony drive. Vector
control mode means that the control algorithm of the drive consists of a closed loop speed control component and a
closed loop torque control component. Since vector control applications require (a) precisely controlled starting
torques (±0.1%), (b) precisely controlled speeds (±0.1%), and/or (c) fast response, such applications use either an
encoder or a magnetic pickup for direct speed control feedback. Typical vector control applications include
centrifuges, extruders and test stands. Compare with standard control.
VHZ - Is an acronym for Volts per Hertz control, one of six control modes in the NXG drive. This mode is intended
for multiple motors connected in parallel. Therefore, it disables spinning load and fast bypass. This is essentially
open-loop vector control with de-tuned (smaller bandwidth obtained by reducing the gain) current regulators.
