System bus interface
The CAN connection of the system bus is physically designed according to ISODIS 11898 (CAN High Speed). The bus topology is the line structure.
In the default version, the frequency inverter supports a CAN protocol controller, which
may exist in either the CM-CAN communication module with CANopen interface OR in
an expansion module for the system bus, such as the EM-IO-02 expansion module.
Attention!
4.1
Installation of two optional components with CAN-Protocol controller results in a deactivation of the system bus interface in the EM-IO-02 expansion module.
Bus termination
The necessary bus terminator at the physically first and last node can alternatively be
activated via the two DIP switches S1 and S2 on the EM-IO-02 expansion module.
•
Either set S1 to ON and S2 to OFF for a regular passive termination,
•
or switch S1 and S2 to ON for an active termination. This results in an improved
edge shape of the CAN signals, which improves the signal shapes, in particular in
extended systems.
Switch S3 is used to configure the analog input (see chapter "Analog input
EM-S1INA“).

Baud rate setting/line length
The setting of the baud rate must be identical in all nodes on the system bus. The
maximum possible baud rate is based on the necessary overall line length of the system bus. The baud rate is set via the parameter Baud-Rate 903 and thus defines the
possible line length.

A baud rate under 50 kBaud, as is defined according to CANopen, is not sensible for
the system bus as the data throughput is too low.
The maximum line lengths stated are guidelines. If they are made complete use of, a
calculation of the admissible length is to be done on the basis of the line parameters
and the bus driver (PCA82C250T).
4.5
Setting node address
A maximum of 63 slaves or frequency inverters with system bus can be operated on
the system bus. Each frequency inverter is given a node ID, which may only exist
once in the system, for its unambiguous identification. The setting of the system bus
node ID is done via the parameter Node-ID 900.

Thus, the system bus possesses a maximum number of 63 nodes (Network nodes),
plus one frequency inverter as a master.
Note:
14
With the factory setting of parameter Node-ID 900 = -1, the system bus
is deactivated for this frequency inverter.
If the Node-ID 900 = 0 is set, the frequency inverter is defined as a master. Only one frequency inverter on the system bus may be defined as a
master.
06/05
4.6
Functional overview
To start with, the system bus produces the physical connection between the frequency
inverters. Logical communication channels are produced via this physical medium.
These channels are defined via the identifiers. As CAN does not possess a nodeoriented, but a message-oriented addressing via the identifiers, the logical channels
can be displayed via it.
In the basic state (factory setting) the identifiers are set according to the Predefined
Connection Set of CANopen. These settings are aimed at one master serving all the
channels. In order to be able to build up process data movement via the PDO channels
between individual or a number of inverters (transverse movement), the setting of the
identifiers in the nodes has to be adapted.
Note:
For understanding, it is important to observe that the data exchange is
done message-oriented. The frequency inverter can transmit and receive a
number of messages, identified via various identifiers.
As a special feature, the properties of the CAN bus mean that the messages transmitted by one node can be received by a number of nodes simultaneously. The error
monitoring methods of the CAN bus result in the message being rejected by all recipients and automatically transmitted again if there is a faulty reception in one receiver.
4.7
Network management
The network management controls the start of all the nodes on the system bus. Nodes
can be started or stopped individually or together. For node recognition in a CAL or
CANopen system, the slaves on the system bus generate a starting telegram (boot-up
report).
If a fault occurs, the slaves automatically transmit a fault report (emergency message).
For the functions of the network management, the methods and NMT telegrams (network management telegrams) defined according to CANopen (CiA DS 301) are used.

4.7.1
SDO channels (parameter data)
Each frequency inverter possesses two SDO channels for the exchange of parameter
data. In a slave device, these are two server SDO's, in a device defined as a master a
client SDO and a server SDO. Attention must be paid to the fact that only one master
for each SDO channel may exist in a system.
Note:
Only one master can initiate by the system bus an exchange of data via
its client SDO.
The identifier assignment for the SDO channels (Rx/Tx) is done according to the Predefined Connection Set.
This assignment can be amended by parameterization, in order to solve identifier conflicts in a larger system in which further devices are on the CAN bus alongside the
frequency inverters.
Attention! In a system in which a frequency inverter works as a master, the identifier allocations for the SDO channel may not be altered.
In this way, an addressing of individual nodes via the field bus/system
bus path of the master frequency inverter is possible.
Parameters are read/written via the SDO channels. With the limitation to the SDO
Segment Protocol Expedited, which minimizes the handling needed for the parameter
exchange, the transmittable data are limited to the uint / int / long types. This permits
complete parameterization of the frequency inverters via the system bus, as all the
settings and practically all the actual values are displayed via these data types.
4.7.2
PDO channels (process data)
Each frequency inverter possesses three PDO channels (Rx/Tx) for the exchange of
process data.
The identifier assignment for the PDO channel (Rx/Tx) is done by default according to
the Predefined Connection Set. This assignment corresponds to an alignment to a
central master control.
In order to produce the logical channels between the devices (transverse movement)
on the system bus, the amendment of the PDO identifiers for Rx/Tx is necessary.
Each PDO channel can be operated with time or SYNC control. In this way, the operation behavior can be set for each PDO channel:
The setting of the operation mode is done via the following parameters:
TxPDO1 Function 930, TxPDO2 Function 932 und TxPDO3 Function 934
RxPDO1 Function 936, RxPDO2 Function 937 und RxPDO3 Function 938
Operation mode
0 -deactivated
1 -time-controlled
2 -SYNC controlled
Function
no exchange of data via the PDO channel (Rx and/or Tx)
Tx-PDO’s cyclically transmit according to the time specification
Rx-PDO‘s are read in with Ta = 1 ms and forward the data
received to the application
Tx-PDO’s transmit the data from the application that are
then current after the arrival of the SYNC telegram.
Rx-PDO’s forward the last data received to the application
after the arrival of the SYNC telegram.
For synchronous PDO’s, the master (PC, PLC or frequency inverter) generates the
SYNC telegram. The identifier assignment for the SYNC telegram is done by default
according to the Predefined Connection Set. This assignment can be altered by
parameterization.

Master functionality
An external control or a frequency inverter defined as a master (node ID = 0) can be
used as a master. The fundamental tasks of the master are controlling the start of the
network (boot-up sequence), generating the SYNC telegram and evaluating the emergency messages of the slaves.
Further, there can be access to the parameterization of all the frequency inverters on
the system bus by means of a field bus connection via the client SDO of the master
frequency inverter.
4.8.1
Control boot-up sequence, network management
The Minimum Capability Boot-Up method defined according to CANopen is used for
the state control of the nodes (nodes).
This method knows the pre-operational, operational and stopped states.
After the initialization phase, all the nodes are in the pre-operational state. The system
bus master transmits the NMT command Start-Remote-Node. With this command,
individual nodes or all the nodes can be started together. The frequency inverter defined as a master starts all the nodes with one command. After receipt of the Start
Remote Node command, the nodes change into the Operational state. From this time
on, process data exchange via the PDO channels is activated.
A master in the form of a PLC/PC can start the nodes on the system bus individually
and also stop them again.
As the slaves on the system bus need different lengths of time to conclude their initialization phases (especially if external components exist alongside the frequency
inverters), an adjustable delay for the change to Operational is necessary. The setting
is done in a frequency inverter defined as a system bus master via Boot-Up Delay
904.

4.8.2
SYNC telegram, generation
If synchronous PDO’s have been created on the system bus, the master must send the
SYNC telegram cyclically. If a frequency inverter has been defined as a system bus
master, the latter must generate the SYNC telegram. The interval for the SYNC telegram of a frequency inverter defined as the system bus master is adjustable. The
SYNC telegram is a telegram without data.
The default identifier = 128 according to the Predefined Connection Set.
If a PC or PLC is used as a master, the identifier of the SYNC telegrams can be
adapted by parameterization on the frequency inverter.
The identifier of the SYNC telegram must be set identically in all nodes on the system
bus.
The setting of the identifier of the SYNC telegram is done via the parameter SYNCIdentifier 918.

The temporal cycle for the SYNC is set on a frequency inverter defined as a system
bus master via the parameter SYNC-Time 919.
Note:

A setting of 0 ms for the parameter SYNC-Time 919 means "no SYNC

4.8.3
Emergency message, reaction
If a slave on the system bus suffers a fault, it transmits the emergency telegram. The
emergency telegram marks the node ID for the identification of the failed node via its
identifier and the existing fault message via its data contents (8 bytes).
After a fault has been acknowledged on the slave, the latter again transmits an emergency telegram with the data content zero.
The emergency telegram has the identifier 128 + node ID ( = 129 ... 191)
The system bus master evaluates the emergency telegrams of the slaves. Its reaction
to an emergency telegram can be set with Emergency Reaction 989.
Operation mode
0 -Error
1 -No Error
Function
The system bus master receives the emergency
telegram and switches-off
The Emergency Telegram is displayed as warning.
Operation mode - parameter 989 = 0 – Error
Behavior of the system bus master in Emergency Reaction 989 = 0 / Error:
As soon as the system bus master receives an emergency telegram, it also breaks
down and reports the failed node on the basis of its ID via the kind of error. Only the
node is reported, not the cause of the error.
The fault message on the system bus master via Current error 260 is 21nn with nn
= node ID (hexadecimal) of the slave in which a fault switch-off exists.
In addition, the system bus master reports the warning Sysbus (0x2000) via the parameter Warnings 270 Bit 13.
If a fault switch-off occurs on a number of slaves, the first slave to transmit its emergency telegram is displayed on the system bus master.
Operation mode - parameter 989 = 1 – No Error
Behavior of the system bus master in Emergency Reaction 989 = 1 / No Error:
As soon as the system bus master receives an emergency telegram, it reports the
warning Sysbus (0x2000) via the parameter Warnings 270 Bit 13.
Note:
20
In both cases, the Boolean variable SysbusEmergency with source number
730 is set to TRUE in the system bus master. It can be used in the system
bus master and (in transmission via a TxPDO) in the slaves for a defined
shutdown.
SysbusEmergency is also set if the system bus master breaks down.
Resetting of SysbusEmergency is done with the fault acknowledgment.
06/05
4.8.4
Client SDO (system bus master)
Each node on the system bus can be addressed via the SDO channels. In this way,
each node can be addressed and parameterized by one master via its client SDO1. All
the parameters of the data types uint/int/long are accessible. String parameters can
not be processed. If a frequency inverter has been defined as a system bus master,
each node on the system bus in this frequency inverter can be addressed by means of
a field bus connection (RS232, RS485, Profibus-DP) via its client SDO1.
Attention! The second SDO channel SDO2 of the frequency inverters is planned for
the parameterization of the frequency inverters via a visualization tool on
the system bus.
The service used is SDO Segment Protocol Expedited according to CANopen. The frequency inverter defined as a system bus master automatically generates the correct
telegrams. If the SDO channel is operated via a PLC/PC on the system bus, the telegrams must be generated according to the specification.

If a PC or PLC is used as a master, the identifier of the SYNC telegrams can be adapted
by parameterization on the frequency inverter. The identifier of the SYNC telegram must
be set identically in all nodes on the system bus.

Emergency message, fault switch-off
As soon as a fault switch-off occurs in a slave frequency inverter, the emergency telegram is transmitted. The emergency telegram marks the node ID for the identification
of the failed node via its identifier and the existing fault message via its data contents
(8 bytes).
The emergency telegram has the identifier 128 + node ID.
After a fault acknowledgment, another emergency telegram is transmitted, with the
data content (Byte 0 ...7) being set to zero this time. This identifies the node's repeated readiness for operation. If a further fault occurs subsequently, it is transmitted
in a new emergency telegram.
The acknowledgment sequence is based on the definitions according to CANopen.

4.9.4
Server SDO1/SDO2
The communication channel for the exchange of parameter data is the SDO channel.
Communication works according to the client/server model. The server is the node
holding the data (here the frequency inverter), the client the node requesting or wanting to alter the data (PLC, PC or frequency inverter as system bus master).
For the frequency inverter, two server SDO channels have been implemented.
The first SDO channel SDO1 is used for the parameterization of the PLC/PC as a master or frequency inverter with field bus connection as a system bus master.
The second SDO channel SDO2 is reserved for a visualization tool for parameterization. An exchange of data can only be implemented by the master via a client SDO.
The SDO channels are stipulated for the server SDO’s via identifiers according to the
Predefined Connection Set to CANopen. As CANopen only provides for and defines one
SDO channel in the Predefined Connection Set, the second SDO channel can be deactivated.
In addition, the number of system bus nodes and the adjustable node ID are limited
to 63.
Identifier assignment according to the Predefined Connection Set:
Identifier Rx-SDO = 1536 + Node-ID
Identifier Tx-SDO = 1408 + Node-ID
(Node-ID = 1 ... 127, Identifier = 1537 ...
1663)
(Node-ID = 1 ... 127, Identifier = 1409 ...
1535)
Identifier assignment for SDO1/SDO2 compatible with the Predefined Connection Set:
Identifier Rx-SDO1 = 1536 + Node-ID (Node-ID = 1 ... 63, Identifier = 1537 ... 1599)
Identifier Tx-SDO1 = 1408 + Node-ID (Node-ID = 1 ... 63, Identifier = 1409 ... 1471)
Identifier Rx-SDO2 = 1600 + Node-ID (Node-ID = 0 ... 63, Identifier = 1600 ... 1663)
Identifier Tx-SDO2 = 1472 + Node-ID (Node-ID = 0 ... 63, Identifier = 1472 ... 1535)
This corresponds to the factory settings of the frequency inverters for the SDO‘s.
The node ID = 0 for SDO2 is the system bus master.
Attention! The SDO2 must be deactivated in a CANopen system in order not to generate any compatibility problems.
If a frequency inverter has been defined as the system bus master, the above settings
for the SDO1 must be maintained in all the frequency inverters. In this way, access to
the parameterization of the frequency inverters via a field bus connection on the master frequency inverter is possible.
The client SDO1 in the master frequency inverter addresses the server SDO1 of the
slaves via the above identifiers.
Attention! The identifiers for a visualization tool on the second SDO channel SDO2
cannot be changed.
06/05
25
If a PC or a PLC is used as a master, the identifiers of the Rx/Tx-SDO1 can be
adapted by parameterization on the frequency inverter.
Attention!
In free assignment of identifiers, there may not be any double occupancy!
The identifier range 129...191 may not be used as the emergency telegrams can be found there.

Expedited. The data (type uint, int, long) are exchanged in a telegram.
Access to the parameters in the frequency inverters with a statement of parameter
number and data set is displayed via the addressing defined for object access pursuant to the specifications of CANopen via Index/Sub-Index.
Index = parameter number / Sub index = data set.
The data to be transmitted have a length of 2 bytes for uint/int and 4 bytes for long.
For standardization and simplification, 4 bytes are always transmitted.
The data are on bytes 4...7 of the SDO telegram.
uint/int variables are transmitted in bytes 4 and 5
with bytes 6 und 7 = 0.
long variables are transmitted in bytes 4...7.

Communication via field bus connection (SDO1)
If a frequency inverter has been defined as the system bus master and equipped with
a field bus interface, access to the parameterization of all the nodes in existence on
the system bus is possible by means of this field bus interface via the first SDO channel (SDO1). An extension has been created in the protocol frame of the field buses for
this purpose.
Attention! The prerequisite for this mechanism is that the identifier setting for the
first SDO channel (SDO1) corresponds to the Predefined Connection Set.
The parameter addressed must also exist in the system bus master.
4.10.2.1 Profibus-DP
If an object with communication channel (PKW) is used in Profibus-DP, access to all
the other nodes on the system bus can be done via it. The structure of the communication channel permits an additional addressing of a system bus node. This is done by
the use of an unused byte in the communication channel.

Process data channels, PDO
4.11.1
Identifier assignment process data channel
The process channel for the exchange of process data under CANopen is the PDO
channel. Up to three PDO channels with differing properties can be used in one device.
The PDO channels are defined via identifiers according to the Predefined Connection
Set to CANopen:
Identifier 1. Rx-PDO =
Identifier 1. Tx-PDO =
512 + Node-ID
384 + Node-ID
Identifier 2. Rx-PDO =
Identifier 2. Tx-PDO =
768 + Node-ID
640 + Node-ID
Identifier 3. Rx-PDO = 1024 + Node-ID
Identifier 3. Tx-PDO = 896 + Node-ID
This corresponds to the factory settings of the frequency inverters for the Rx/TxPDO‘s. This occupancy is aligned to an external master (PLC/PC) serving all the channels.
If the PDO channels are used for a connection of the frequency inverters amongst one
another, the identifiers are to be set accordingly by parameterization.
Attention! In free assignment of identifiers, there may not be any double occupancy!
The identifier range 129...191 may not be used as the emergency telegrams can be found there.

Operation modes process data channel
The transmit/receive behavior can be time controlled or controlled via a SYNC telegram. The behavior can be parameterized for each PDO channel.
Tx-PDO’s can work time controlled or SYNC controlled. A time controlled TxPDO
transmits its data at the interval of time set. A SYNC controlled TxPDO transmits its
data after the arrival of a SYNC telegram.
RxPDO’s in the time controlled setting forward the received data to the application
immediately. If an RxPDO has been defined as SYNC controlled, it forwards its received data to the application after the arrival of a SYNC telegram.

Communication relationships of the process data
channel
Regardless of the process data to be transmitted, the communication relationships of
the process data channels must be defined. The connection of PDO channels is done
via the assignment of the identifiers. The identifiers of Rx-/Tx-PDO must match in each
case.
There are two principal possibilities:
-
one Rx-PDO to one Tx-PDO (one to one)
connect several Rx-PDO’s to one TxPDO (one to many)
This process is documented in a tabular form via a communication relationship
list.
Example:

Virtual links
According to CANopen, a PDO telegram contains 0...8 data bytes. A mapping for any
kind of objects can be done in these data bytes.
For the system bus, the PDO telegrams are firmly defined with 8 data bytes. The mapping is not done via mapping parameters as with CANopen, but via the method of
sources and links.
Each function provides its output data via a source. These sources are defined via
source numbers. The input data of functions are defined via parameters. The link of a
data input to a data output is done via the assignment of parameters to source numbers.
Example 1:
Function A
Source-No. 27
Function C
Parameter 125
Function B
Parameter 187
Source-No. 5
In example 1, the two inputs of function C are connected with the outputs of functions
A and B. Thus, the parameterization for this connection is:
Function C
Parameter 125 = Source-No. 27
Parameter 187 = Source-No. 5
Example of a virtual link in VPlus:
Parameter
(Softwarefunction)
Source-No.
(Operation mode)
e.g. Start-clockwise 068
e.g. 71-S2IND
Digital input
The assignment of the operation modes to the software functions available can be
adapted to the application in question.
06/05
35
For the system bus, the input data of the TxPDO’s are also displayed as input parameters and the output data of the RxPDO’s as sources.
Example 2:
Function A

Source-No. 27
TxPDO
Inverter 1

RxPDO
Inverter 2
Parameter 972
Function C
Inverter 2
Source-No. 727
Parameter 125
Source-No. 724
Parameter 187
system bus
Example 2 displays the same situation as Example 1. But now, the functions A and B
are in frequency inverter 1 and function C in frequency inverter 2. The connection is
done via a TxPDO in frequency inverter 1 and a RxPDO in frequency inverter 2. Thus,
the parameterization for this connection is:
Frequency inverter 1
Parameter 977 = Source-No. 27
Parameter 972 = Source-No. 5
Frequency inverter 2
Parameter 125 = Source-No. 727
Parameter 187 = Source-No. 724
As the links with the system used exceed the device limits, they are termed "virtual
links".
36
06/05
The virtual links with the possible sources are related to the Rx/TxPDO channels. For
this purpose, the eight bytes of the Rx-/TxPDO’s are defined structured as inputs and
sources. This exists for each of the three PDO channels.
Each transmit PDO and receive PDO can be occupied as follows:
4 Boolean variables
or
4 uint/int variables 4 uint/int variables
or
2 long variables
or
a mixture paying attention to the eight bytes available

With this method, there are up to three possibilities for a meaning of the contents of
the individual bytes. Each byte may only be used for one possibility.
To ensure this, the processing of the input links is derived from the setting.
If an input link has been set to the fixed value of zero, it is not processed.
The settings for the fixed value zero are:
Source =
Source =
7 (FALSE)
9 (0)
for boolean variables
for uint/int, long variables
This is simultaneously the factory setting.

The control word of frequency inverter 1 is linked with the control word of frequency
inverter 2. In this way, both frequency inverters can be operated synchronously via
the remote control. The output of the reference value channel of frequency inverter 1
is laid onto the output of the ramp of frequency inverter 2. In this way, both frequency
inverters have a joint source of reference values and are given reference values in the
internal notation.
As an extension, a number of frequency inverters can also exist on the receive side
(Rx), these then being supplied with data parallel and simultaneously.
The input link not used in the TxPDO1 of frequency inverter 1 is on ZERO and is thus
not served.

Control parameters
For the monitoring of the system bus and the display of the internal states, two control parameters are provided. There is a report of the system bus state and a report of
the CAN state via two actual value parameters.
The parameter Node-State 978 gives information about the Pre-Operational, Operational, Stopped state. A PDO transfer is only possible in the Operational state. The
state is controlled by the system bus master (PLC / PC / frequency inverter) via NMT
telegrams.
The parameter CAN-State 979 gives information about the state of the physical layer.
If there are transmission errors, the state changes from OKAY to WARNING until the
cancellation of the communication with BUS-OFF. After BUS-OFF, the CAN controller is
automatically re-initialized and the system bus started again.
Note:
If the BUS-OFF state occurs, the frequency inverter breaks down with
"F2210 BUS-OFF".
After Bus-OFF, the system bus in the frequency inverter is completely reinitialized.
There is a new boot-up message from the node and an emergency telegram with the
Bus-OFF message is transmitted. The change of state of the node to Operational is
done by the Start-Remote-Node telegram cyclically sent by the system bus master.

4.13
Handling of the parameters of the system bus
As soon as the system bus expansion module EM-SYS exists in an frequency inverter,
the actual value parameters for system state and bus state are activated and can be
observed in the actual value menu VAL of the control unit KP500 or with the VPlus PC
program in the menu Actual values \ System bus.
Note:
The actual value parameters are on control level 3 and are thus available
for the user at any time.
All the setting parameters for the configuration of the system bus are not directly accessible for the user. For defined customer applications, pre-defined XPI files can be
generated by VECTRON for the VPlus PC program, with which the necessary parameters are visible for the user. The application-relevant variables are then available in
these XPI files.
Note:
XPI files can be read in addition to the loaded parameter information of
the frequency inverter into the VPlus PC program.
In the menu of the software under the point Edit you find the command
"Read in XPI file".
The method of working via an XPI file has its reasoning in the fact that deep interventions in the system are possible via the system bus and can lead to serious problems
in the application with an untrained user. Via the XPI files, a user is given a selection
list pre-defined by VECTRON.
Attention! The configuration of the necessary parameters for the system bus are
accessible by a XPI file with the help of the VPlus PC program.
The control unit KP500 does not support this functionality.
If the expansion module system bus EM-SYS is installed additionally to a
communication module for the field bus connection (CM-232, CM-485 or
CM-PDP) in the frequency inverter, the parameterization can be made
with the interface adapter KP232.
Experienced users have complete access to all the existing sources and possible input
links with the XPI file of the active functions. The selection depends on the selected
configuration and control procedure.
The display of the parameters when using the XPI file is according to the following
structure:

Utilities
For the planning of the system bus according to the drive tasks in question, there are
utilities in the form of tables.
The planning of the system bus is done in three steps:
1.
2.
3.
Definition of the communication relationships
Production of the virtual links
Capacity check
The priority assignment of the identifiers is relevant for the definition of the communication relationships. Data that are to be transmitted with a higher priority must be
given low identifiers. This results in the message with the higher priority being transmitted first with a simultaneous access of two nodes to the bus.
Note:
The recommended identifier range for the communication relationships via
the PDO channels is 385 ... 1407.
The identifiers below 385 are used for the NMT telegrams (boot-up sequence, SYNC telegram) and emergency message.
The identifiers above 1407 are used for the SDO channel for parameterization.

Capacity planning of the system bus
Each PDO telegram possesses a constant useful data content of 8 Bytes. According to
worst case, this results in a maximum telegram length of 140 bits. The maximum telegram run time of the PDO’s is thus stipulated via the set baud rate.

Attention! A bus load >100% means that a telegram cannot be dispatched completely between two transmission times.
Such a setting is not admissible!
This observation must be done for each TxPDO. The sum of all the TxPDO’s decides on
the entire bus load. The bus load must be designed in such a way that any telegram
repetitions for transmission errors are possible without exceeding the bus capacity.

5.1.1
Analog input EM-S1INA
General
The analog input of the EM-IO-02 expansion module can optionally be configured as a
voltage or a current input. Parameterization of the input signal is done by the definition of a linear characteristic and assignment as a
− reference value source
(can be selected via the parameter Reference frequency source 475),
− reference percentage source
(can be selected via the parameter Reference percentage source 476),
− actual percentage source
(can be selected via the parameter Actual percentage source 478, in configuration x11) or
− limit value sources
(can be selected via the parameter Limit Source 734…737).

Characteristic
The mapping of the analog input signals onto a frequency or percentage reference
value is possible for various demands. The parameterization is to be done via two
points of the linear characteristic of the reference channel.
The characteristic point 1, with the coordinates X1 and Y1, and the characteristic point
2, with the coordinates X2 and Y2, are to be set in the four data sets.
The characteristic points X1 and X2 are stated as percentages, as the analog input can
be switched as a current or voltage input via switch S3.

The coordinates of the characteristic points are related as a percentage to the analog
signal, with 10 V or 20 mA, and the parameter Maximum Frequency 419 or parameter Maximum reference percentage 519. The change of direction of rotation can be
done via the digital inputs and/or by selecting the characteristic points.
The definition of the analog input characteristic can be calculated via the two-point
form of the straight line equation. The speed Y of the drive mechanism is controlled
according to the analog control signal X.

Attention! Monitoring of the analog input signal via the parameter Error/Warning
Behavior 563 demands a check of the characteristic parameters. Sensible
use is only possible if the Characteristic point X1 564 is in the positive
range.
5.1.4
Operation modes
The operation modes of the analog input characteristic enable application-related scaling as a supplement to the characteristic points stated. One of the four linear types of
characteristic is selected for adaptation of the signal for the analog input signal via the
parameter Operation mode 562.
If the characteristic points are not suited for the type of characteristic selected, the
characteristic points are corrected internally.
Operation mode
1 -bipolar
11 -unipolar
21 -unipolar
2…10 V / 4…20 mA
101 -bipolar abs. value
Function
The analog input signal is mapped onto the reference
figure according to the characteristic points (X1/Y1)
and (X2/Y2).
With a negative parameter value of the characteristic
points X1 or X2, they are mapped to the reference
value zero.
If the characteristic points X1 or X2 have been set with
a negative parameter figure or smaller than 0%, the
input characteristic is mapped to the reference value
20%.
Negative parameter values of the characteristic points
Y1 or Y2 are mapped as a positive reference value in
the characteristic.
Further information on the operation modes stated in the table can be found in the
following chapter "Examples“.

5.1.4.1
Examples
The analog input signal is mapped onto a reference value as a function of the characteristic. The following examples show the operation modes for an analog voltage signal. The parameter Minimum Frequency 418 is set to the value 0.00 Hz. The characteristic point 100% for the Y axis corresponds to the parameter Maximum Frequency
419 of 50.00 Hz in the examples.
Attention! The various operation modes change the input characteristic as a function
of the parameterized characteristic points. In the following examples, the
areas of the system of coordinates from which a characteristic point is
displaced are marked.
Operation mode "1 – bipolar"
In operation mode "1 – bipolar“, the characteristic of the analog input can be freely
set by stating two characteristic points.

4.85 V, with a tolerance band of ±0.20 V.
Operation mode "21 – unipolar 2…10 V / 4…20 mA"
This operation mode limits the input characteristic to the range between 20% and
100% of the analog signal. If the value for a characteristic point of the X axis is outside 0%, it is mapped to the characteristic point (2 V / 0 Hz).
The characteristic point on the X axis is calculated according to the following formula:
characteri stic point X = parameter value X ⋅ (100.00% - 20.00%) + 20.00%

Operation mode "101 – bipolar abs. value"
The operation mode "101 – bipolar abs. value“ maps the bipolar analog signal onto a
unipolar input characteristic. The formation of the absolute value takes the characteristic into account comparable to the "bipolar" operation mode, but the characteristic
points are reflected on the X axis with a negative value for the Y axis.

Y2 = 85.00% · 50.00 Hz = 42.50 Hz
Tolerance band:
ΔX = 2.00% · 10 V = 0.20 V
In this example, the reference value is
again increased from an analog input signal of -1.44 V with a tolerance band of
±0.20 V. The theoretical change of sign of
the reference value is taken into account
and leads to the tolerance band stated.
There is no change of the direction of
rotation.
Scaling
The analog input signal is mapped to the freely configurable characteristic. The maximum admissible setting range of the drive mechanism is to be set according to the
configuration selected via the frequency limits or the percentage value limits. In the
parameterization of a bipolar characteristic, the minimum and maximum limit for both
directions of rotation are taken over. The percentage values of the characteristic
points are relative to the maximum limits selected.

Error and warning behavior
The monitoring of the analog input signal necessary according to the application is to
be configured via the parameter Error/Warning behavior 563.
Operation mode
0 -Off
1 -Warning < 1 V / 2 mA
2 -Shutdown < 1 V / 2 mA
Fault switch-off
3< 1 V / 2 mA
Function
The input signal is not monitored.
If the input signal is less than 1 V or 2 mA, there is
a warning message.
If the input signal is less than 1 V or 2 mA, there is
a warning message, the drive mechanism is decelerated according to stopping behavior 1.
If the input signal is less than 1 V or 2 mA, there is
a warning and fault message and the drive mechanism stops freely.
The monitoring of the analog input signal is active independent of the release of the
frequency inverter according to the operation mode selected.
In operation mode 2, the drive mechanism is decelerated independent of the stopping
behavior set (Parameter Operation mode 630) according to stopping behavior 1
(shutdown and switch-off). If the set holding time has expired, there is a fault message. A repeat start of the drive mechanism is possible by switching the start signal on
and off if the fault has been cleared beforehand.
Operation mode 3 defines the free stoppage of the drive mechanism, independent of
the stopping behavior selected, which is stipulated with the parameter Stop function
630.
Attention! Monitoring of the analog input signal via the parameter Error/Warning
Behavior 563 demands a check of the characteristic parameters.

This completes the adjustment of the analog input.
5.1.9
Filter time constant
The time constant of the filter for the reference analog value can be set via the parameter Filter time constant 561.
The time constant states the time for which the input signal is averaged by means of a

Zero adjustment and amplification
After the adjustment has been carried out, the voltage of the output signal at 0% and
100% of the reference signals can be set with the parameters Offset 585 (zero adjustment) and Amplification 586.
The zero adjustment with the parameter Offset 585 is done specific to the application
as a percentage of the final value of the analog output (10 V).
Via the parameter Amplification 586 the amplification can be set as a percentage of
the final value of the analog output (10 V).
In the factory setting, the zero point has been set at 0% Offset, i.e. minimum value of
the reference signal equal to 0 V output signal. The factory setting amplification equal
to 100% means that the output signal is 10 V when the reference value is reached.

Digital output EM-S1OUTD
5.3.1
General
The digital output of the EM-IO-02 expansion module is designed as a make contact
relay. Parameterization of this digital output permits a linking to a variety of functions.
The selection of functions depends on the parameterized configuration.
5.3.2
Operation modes
The operation mode of the digital output (Terminals X410A.6 and 7) is selected via the
parameter Operation Mode EM-S1OUTD 533.
The operation modes to be selected correspond to the table shown in the operating
instructions of the frequency inverter in the chapter "Digital outputs“.
5.4
Digital inputs EM-SxIND
The EM-IO-02 expansion module has three digital inputs. The assignment of the control
signals to the available software functions can be adapted to the application in question. As a function of the selected Configuration 30, the factory-set assignment and
the selection of the operation mode differ. In addition to the digital control inputs available, further internal logistic signals are also available as sources.
The individual software functions are assigned to the various signal sources via parameterization-capable inputs. This enables a flexible and varied use of the digital control
signals.

The three digital inputs of the EM-IO-02 expansion module can be set via the parameter Operation mode Speed sensor 2 493 and selection of the corresponding operation
mode for the evaluation of a unipolar 24V two-channel speed sensor (incremental
speed sensor).
For parameter analog mode 553, the additional operation mode 4 – abs. value speed
sensor 2 can be selected, which can output the abs. value of the speed sensor signal 2
in the range from 0.00 Hz to maximum frequency 419 via the multifunctional output

(Alternative to exchanging the track signals).
Division marks
The number of increments of the connected speed sensor can be adjusted via the
parameter Division marks speed sensor 2 494. The number of division marks of the
speed sensor is to be selected according to the speed range of the application.
The maximum number of division marks Smax is defined by the limit frequency of
fmax = 150 kHz of the digital inputs EM-S2IND (track A) and EM-S3IND (track B).
S max = 150000 Hz ⋅
60s/ min

nmax = Max. speed of the motor in RPM
To ensure a good true running of the drive mechanism, a sensor signal must be
evaluated at least every 2 ms (signal frequency f = 500 Hz). The minimum number of
division marks Smin of the incremental speed sensor for a required minimum speed
nmin can be calculated from this requirement. The evaluation of four signal edges per
mark is firmly defined in the function of speed sensor 2.
