12 Getting Started, 10/2013, FW V4.6, A5E32899990B AA
1.4
Residual risks of power drive systems
The control and drive components of a drive system are approved for industrial and
commercial use in industrial line supplies. Their use in public line supplies requires a
different configuration and/or additional measures.
These components may only be operated in closed housings or in higher-level control
cabinets with protective covers that are closed, and when all of the protective devices are
used.
These components may only be handled by qualified and trained technical personnel who
are knowledgeable and observe all of the safety instructions on the components and in the
associated technical user documentation.
When assessing the machine's risk in accordance with the respective local regulations (e.g.,
EC Machinery Directive), the machine manufacturer must take into account the following
residual risks emanating from the control and drive components of a drive system:
1. Unintentional movements of driven machine components during commissioning,
operation, maintenance, and repairs caused by, for example:
– Hardware defects and/or software errors in the sensors, controllers, actuators, and
connection technology
– Response times of the controller and drive
– Operating and/or ambient conditions outside of the specification
– Condensation / conductive contamination
– Parameterization, programming, cabling, and installation errors
– Use of radio devices / cellular phones in the immediate vicinity of the controller
– External influences / damage
2. In the event of a fault, exceptionally high temperatures, including an open fire, as well as
emissions of light, noise, particles, gases, etc. can occur inside and outside the inverter,
e.g.:
– Component malfunctions
– Software errors
– Operating and/or ambient conditions outside of the specification
– External influences / damage
Inverters of the Open Type / IP20 degree of protection must be installed in a metal control
cabinet (or protected by another equivalent measure) such that the contact with fire inside
and outside the inverter is not possible.

3. Hazardous shock voltages caused by, for example:
– Component malfunctions
– Influence of electrostatic charging
– Induction of voltages in moving motors
– Operating and/or ambient conditions outside of the specification
– Condensation / conductive contamination
– External influences / damage
4. Electrical, magnetic and electromagnetic fields generated in operation that can pose a
risk to people with a pacemaker, implants or metal replacement joints, etc. if they are too
close.
5. Release of environmental pollutants or emissions as a result of improper operation of the
system and/or failure to dispose of components safely and correctly.
Note
The components must be protected against conductive contamination (e.g. by installing them
in a control cabinet with degree of
protection IP54 according to IEC 60529 or NEMA 12).
Assuming that conductive contamination at the installation site can definitely be excluded, a
lower degree of cabinet protection may be permitted.

Finding a suitable setting for the interfaces
The inputs and outputs of the frequency inverter and the fieldbus interface have specific
functions when set to the factory settings.
When you put the frequency inverter into operation, you can change the function of each of
its inputs and outputs and the setting of the fieldbus interface.
To make the setting process easier, the inverter has various predefined assignments

Wiring the terminal strip
NOTICE
Damage to the inverter when using long signal cables
Using long cables at the inverter's digital inputs and 24 V power supply can lead to
overvoltage during switching operations. Overvoltages can damage the inverter.
• If you use cables of more than 30 m at the digital inputs and 24 V power supply, connect
an overvoltage protection element between the terminal and the associated reference
potential.
We recommend using the Weidmüller overvoltage protection terminal with designation
MCZ OVP TAZ DIODE 24VDC.
WARNING
Danger to life as a result of hazardous voltages when connecting an unsuitable power
supply
Death or serious injury can result when live parts are touched in the event of a fault.
• For all connections and terminals of the electronic modules, only use power supplies
with protective extra low voltage (PELV), Class 2.

• Before switching on, check that no parts are loose on the machine or can be spun out.
• Before switching on, ensure that nobody is working on the machine or located within its
working area.
• Secure the machine's work area against unintended access.
• Lower hanging/suspended loads to the floor.
Procedure
To initiate motor data identification and optimization of the motor control, proceed as follows:
1.
Open by double-clicking on the control panel in
STARTER.
2.
Assume master control for the converter.
3.
Set the "Enable signals"
4.
Switch on the motor.
The converter starts the motor data identification.
This measurement can take several minutes.
After the measurement, the converter switches off
the motor.
5.
Relinquish the master control after the motor data
identification.
6.
Click the Save (RAM to ROM) button.
You have now completed motor data identification.
Self-optimization of the closed-loop control
