1.2.1. Safety Note
The voltage of the frequency converter is dangerous whenever connected to mains.
Incorrect installation of the motor, frequency converter or fieldbus may cause damage
to the equipment, serious personal injury or death. Consequently, the instructions
in this manual, as well as national and local rules and safety regulations, must
be complied with.
1.2.2. Safety Regulations
1.
The frequency converter must be disconnected from mains if repair work is to be carried
out. Check that the mains supply has been disconnected and that the necessary time has
passed before removing motor and mains plugs.
2.
The [STOP/RESET] key on the control panel of the frequency converter does not disconnect
the equipment from mains and is thus not to be used as a safety switch. 3.
Correct protective earthing of the equipment must be established, the user must be protected
against supply voltage, and the motor must be protected against overload in
accordance with applicable national and local regulations.
3.
Correct protective earthing of the equipment must be established, the user must be protected
against supply voltage, and the motor must be protected against overload in
accordance with applicable national and local regulations.
4.
The earth leakage currents are higher than 3.5 mA.
5.
Protection against motor overload is not included in the factory setting. If this function
is desired, set par. 1-90 Motor Thermal Protection to data value ETR trip or data value
ETR warning. Note: The function is initialised at 1.16 x rated motor current and rated
motor frequency. For the North American market: The ETR functions provide class 20
motor overload protection in accordance with NEC.
6.
Do not remove the plugs for the motor and mains supply while the frequency converter
is connected to mains. Check that the mains supply has been disconnected and that the
necessary time has passed before removing motor and mains plugs.
7.
Please note that the frequency converter has more voltage inputs than L1, L2 and L3,
when load sharing (linking of DC intermediate circuit) and external 24 V DC have been
installed. Check that all voltage inputs have been disconnected and that the necessary
time has passed before commencing repair work.
1.2.3. Warning Against Unintended Start
1.
The motor can be brought to a stop by means of digital commands, bus commands,
references or a local stop, while the
frequency converter is connected to mains. If personal
safety considerations make it necessary to ensure that no unintended start occurs,
these stop functions are not sufficient.
2.
While parameters are being changed, the motor may start. Consequently, the stop key
[STOP/RESET] must always be activated; following which data can be modified.
3.
A motor that has been stopped may start if faults occur in the electronics of the frequency
converter, or if a temporary overload or a fault in the supply mains or the motor connection
ceases.
1.2.4. Warning
Touching the electrical parts may be fatal - even after the equipment has been disconnected
from mains.

1. Introduction
Also make sure that other voltage inputs have been disconnected, such as external 24 V DC, load
sharing (linkage of DC intermediate circuit), as well as the motor connection for kinetic back up.
Please refer to the relevant Operating Instructions for further safety guidelines.

1.4. About PROFIBUS
PROFIBUS is standardized in the international standards IEC 61158 and IEC 61784, and supported
by the member companies of the PROFIBUS International user community.
PROFIBUS International (PI) is the umbrella organization for all Regional PROFIBUS Associations
(RPA) worldwide. PI has engaged PNO (PROFIBUS Nutzerorganisation e. V.), Germany, a nonprofit
organisation based in Karlsruhe, Germany, to establish Technical Committees and Working
Groups in order to define and maintain the open and vendor independent PROFIBUS technology.
Any member of PROFIBUS International may take an active part in maintenance and further development
of the PROFIBUS technology. This guarantees openness and vendor independence of
the PROFIBUS technology.
For access to the vast quantity of PROFIBUS literature including information and downloads for
PROFIBUS DP and the PROFIdrive profile, please refer to www.profibus.
1.5. About PROFIBUS DP V1

1.6.1. Bus Topology
Single master
-PLC communicates with telegrams of
constant length
-
Fits time-critical requirements
-Cyclical transmission via PPO types
-Extended diagnosis
Illustration 1.1: PROFIBUS DP V0
1.6.2. Bus Topology
Multiple master
Features of a Master class 1 connection
-Cyclical data exchange (DP V0)
-Acyclical read/write on parameters
-Extended diagnosis
The acyclical connection is fixed, and cannot
be changed during opera
tion.
Features of a Master class 2 connection:
-Initiate / Abort acyclical connection
-Acyclical read/write on parameters
Illustration 1.2: PROFIBUS DP V1
The acyclical connection can be established
(Initiate) or removed (Abort) dynamically
even when a master class 1 is active on the
network. The DP V1 acyclical connection can
be used for general parameter access as an
alternative to the PCV parameter channel.
The PROFIBUS DP extension DP V1 permits acyclical as well as cyclical data communication. This
feature can be used by a DP master class 1 (e.g. PLC), as well as a DP master class 2 (e.g. PC
tool).
