PROFIBUS (PROcess FieldBUS) is a standard for Fieldbus communication in
automation technology
PROFIBUS DP (PROFIBUS for Decentralised Peripherals) is an implementa-
tion of PROFIBUS optimized for distributed I/O applications. PROFIBUS DP
devices can co-exist with non-DP PROFIBUS devices on the same bus.
PROFIBUS FMS (PROFIBUS Fieldbus Message Specification) is an imple-
mentation of the PROFIBUS tailored for demanding communication tasks.
PROFIBUS FMS devices can co-exist with non-FMS PROFIBUS devices on
the same bus.
PROFIdrive implements a common PROFIBUS DP device profile for motion
control applications such as drives and Inverters.
Some products allow customisation of their behaviour by allowing the execu-
tion of a sequence of user instructions.
Electrical termination of a signal involves providing a terminator at the end of
a wire or cable. Termination prevents an RF signal from causing interference
by being reflected back at the end of the cable.
The rotational force exerted by a motor shaft. The units of measurement con-
sist of the distance (radius from shaft centre axis) and force applied at that
distance. Units are usually given as Newton-meters, pound-feet or ounce-
inches.
An undesired event that causes the Inverter to stop operation is called a "trip"
event (as in tripping a circuit breaker). The Inverter keeps a history log of trip
events. They also require an action to clear.
Within the context of this document, Unit refers to the 3G3AX-MX2-PRT-E
Option Board.
A Variable Speed Drive is a piece of equipment used to control the speed of
machinery.
The monitored output frequency is called HIW in the PROFIdrive device pro-
file.
The commanded frequency reference is called HSW in the PROFIdrive device
profile.
The combination of the task ID and parameter number in the PKW messaging
area is called PKE in the PROFIdrive device profile.
The parameter processing messaging area is called PKW in the PROFIdrive
device profile.
The parameter number is called PNU in the PROFIdrive device profile.
The parameter value in the PKW messaging area is called PWE in the PRO-
FIdrive device profile.
The process data (cyclically transferred) is called PZD in the PROFIdrive
device profile.
The control word is called STW in the PROFIdrive device profile.
The status word is called ZSW in the PROFIdrive device profile.
