1General Safety Instructions and Information on Use
Warning!
The specifications and instructions contained in the documentation must be complied
with strictly during installation and commissioning. Before starting the relevant ac-
tivity, read the documentation carefully and comply with the safety instructions. The
term "Qualified Staff" refers to anybody who is familiar with the installation, assem-
bly, commissioning and operation of the frequency inverter and has the proper qua-
lification for the job.
1.1 General Information
Warning!
The DC-link circuit of the frequency inverter is charged during operation, i.e. there is
always the risk of contact with high voltage. Frequency inverters are used for driving
moving parts and they may become hot at the surface during operation.
Any unauthorized removal of the necessary covers, improper use, wrong installation
or operation may result in serious injuries or material damage.
In order to avoid such injuries or damage, only qualified technical staff may carry
out the transport, installation, commissioning, setup or maintenance work required.
The standards EN 50178, IEC 60364 (Cenelec HD 384 or DIN VDE 0100), IEC
60664-1 (Cenelec HD 625 or VDE 0110-1) as well as the applicable national regula-
tions must be complied with. The term „Qualified Staff“ refers to anybody who is
familiar with the installation, assembly, commissioning and operation of the frequen-
cy inverter as well as the possible hazards and has the proper qualification for the
job.
Persons who are not familiar with the operation of the frequency inverter and child-
ren must not have access to the device.
1.2 Purpose of the Frequency Inverters
Warning!
The frequency inverters are electrical drive components intended for installation in
industrial plants or machines. Commissioning and start of operation is not allowed
until it has been verified that the machine meets the requirements of the EC Machi-
nery Directive 2006/42/EEC and EN 60204. In accordance with the CE marking re-
quirements, the frequency inverters comply with the Low Voltage Directive
2006/95/EC as well as EN 61800-5-1. The user shall be responsible for making sure
that the requirements of the EMC Directive 2004/108/EEC are met. Frequency inver-
ters are only available at specialized dealers and are exclusively intended for profes-
sional use as per EN 61000-3-2.
Purposes other than intended may result in the exclusion of warranty.
The frequency inverters are also marked with the UL label according to UL508c,
which proves that they also meet the requirements of the CSA Standard C22.2-No.
14-95.
The technical data, connection specifications and information on ambient conditions
are indicated on the name plate and in the documentation and must be complied
with in any case. Anyone involved in any kind of work at the device must have read
the instructions carefully and understood them before starting the work.
1.3 Transport and Storage
The frequency inverters must be transported and stored in an appropriate way. During trans-
port and storage the devices must remain in their original packaging.
The units may only be stored in dry rooms which are protected against dust and moisture. The
units may be exposed to little temperature deviations only. Observe the conditions according to
EN 60721-3-1 for storage, EN 60721-3-2 for transport and the marking on the packaging.

The duration of storage without connection to the permissible nominal voltage may not exceed
one year.
1.4 Handling and Installation
Warning!
Damaged or destroyed components must not be put into operation because they may
be a health hazard.
The frequency inverters are to be used in accordance with the documentation as well as the
applicable directives and standards.
They must be handled carefully and protected against mechanical stress.
Do not bend any components or change the isolating distances.
Do not touch electronic components or contacts. The devices are equipped with components
which are sensitive to electrostatic energy and can be damaged if handled improperly. Any use
of damaged or destroyed components shall be considered as a non-compliance with the appli-
cable standards.
Removal of seal marks may cause restrictions on warranty.
Do not remove any warning signs from the device.
1.5 Electrical Installation
Warning!
Before any assembly or connection work, discharge the frequency inverter. Verify
that the frequency inverter is discharged.
Do not touch the terminals because the capacitors may still be charged.
Comply with the information given in the operating instructions and on the frequen-
cy inverter label.
Comply with the rules for working on electrical installations.
Rules for working on electrical installation:
−Separate completely (isolate the installation from all possible sources of electrical power.
−Fix (protect against reconnection). Reconnection must be carried out by suitably qualified
persons.
−Verify there is no electrical power. Verify that there is no voltage against earth on the plant
component by measuring with measurement device or voltage tester.
−Ground and connect in a short circuit. Connect earth conductors.
−Protect against nearby power sources and delimit the working zone.
1) In plants with a nominal power up to 1 kV deviation from description may be possible.
When working at the frequency inverters, comply with the relevant accident prevention regula-
tions, the applicable standards, standards governing work on systems with dangerous voltages
(e.g. EN 50178), directives for electrical and mechanical equipment erection and other national
directives.
Comply with the electrical installation instructions given in the documentation as well as the
relevant directives.
Responsibility for compliance with and examination of the limit values of the EMC product norm
EN 61800-3 for variable-speed electrical drive mechanisms is with the manu-facturer of the
industrial plant or machine. The documentation contains information on EMC-conforming instal-
lation.
The cables connected to the frequency inverters may not be subjected to high-voltage insula-
tion tests unless appropriate circuitry measures are taken before.
Do not connect any capacitive loads.

2Description of System VPLC
With the PLC functions (VPLC), external digital signals and internal logic signals of the frequen-
cy inverter can be combined with one another. Via analog and mathematical functions, analog
signals can be influenced or compared, the results are available for output. PLC functions are
also referred to as instructions.
The results of the instructions can be used by other device functions (e.g. comparator) or out-
put via digital outputs. The results can also be used as input values by other instructions.
The instructions can be configured via function blocks in VPLC.
The functions are processed from index to index (I).
VPLC:
−Up to 32 functions are possible.
−Each function block describes an instruction.
−The processing order corresponds to the order of indices 1 to max. 32.
Input settings (digital)
−Via a digital input buffer, digital signal sources (e.g. run signal, error signal) and digital
inputs (e.g. IN2D) can be assigned to the instruction inputs. The input buffer enables 16 en-
tries.
Input settings (analog)
−Via an analog input buffer, analog signal sources (e.g. frequencies) can be assigned to the
instruction inputs. Via the input buffers 4 inputs each can be selected for frequencies, per-
centages, currents and voltages.
Analog output settings
−Via an output buffer, the output values of the instructions can be made generally (globally)
available and used by other functions (e.g. start clockwise, data set change-over) or output
via the digital outputs of the device. Up to 16 signal sources can be used as digital output
buffer, 24 signal sources can be used as analog output buffer.
−All output values of the instructions have defined values when the frequency inverter is in-
itialized. They are FALSE (digital instructions) or have value 0 (analog instructions) for all in-
struction outputs and all output buffer values. Inverted instruction outputs will be TRUE after
initialization.
−Processing of the instructions can be activated via button "Start PLC" and deactivated via
button "Stop PLC".
Consistent data
The input buffer and output buffer guarantee consistent data during the run time.
Each instruction is described by:
−Instruction (digital: AND, OR etc., analog: addition, absolute value function, etc).
−Inputs: Inputs of the instructions (digital, analog or position).
−Function block settings: These parameters enable, depending on the selected instruction,
setting of delay times, factors or jumps between functions, for example.
−Outputs of instructions: The value of an output can be moved to the output buffer and is
now generally (globally) available to other device functions.
Each instruction has two outputs O1 and O2 (O2 = O1 inverted) or O1 = Low word and O2 =
High word).
The output values of instructions can also be used as input values in other instructions.
Values are interpreted as Percentage value internal
Internal values of the frequency inverter are processed as percentage value. Frequencies, Cur-
rents and voltage are converted.
Also Input- and Output buffer convert into percentage values.
−Current: Refers to the inverter nominal current. The inverter nominal current refers to
100.00 %

VPLC / PLC 1108/10
08/10 VPLC / PLC 11
−Frequency: Refers to Maximum Frequency 419. Maximum Frequency 419 refers to
100.00 %
−Voltage: Refers to 400 Veff (bzw. 400 √2 Vpeak). The value refers to 100.00 %.
Mathematical functions use percentage values as input and output values.
Internal conversions
Internal values of the frequency inverter are processed as percentage value. Frequencies, Cur-
rents and voltage are converted.

The instructions are processed cyclically. In the first step, the output buffer is written to the
global variables, then the input buffer is written to the sources.
Then the instructions are processed, starting with Index 1.

VPLC / PLC 08/1012
12 VPLC / PLC 08/10
A cycle is complete, if all used and successive instructions have been processed. Then the
processing cycle is started again (write output buffer, update input buffer, index 1, index 2, …).
The processing time of each instruction is approx. 1 ms.
Additionally, 1 ms is required for writing the output signals 24xx/25xx and reading of input sig-
nals 20xx/23xx.
As a result, the cycle time is the total of instructions + 1 in milliseconds.
