Overview of the System

1 Overview of the System

The UFI11A INTERBUS fieldbus interface serves as a gateway for connecting one or
more MOVIDRIVE, MOVIDRIVEcompact or MOVITRAC 07 inverters to INTERBUS. Se­veral inverters can be connected to the INTERBUS UFI11A interface via the SBus. The
INTERBUS UFI11A interface provides the translation between the INTERBUS and the
SBus.

The UFI11A settings can be copied with the UBP11A parameter module from UFI11A
to UFI11A. For safety reasons, all inverters connected to the UFI11A must be turned off
when writing data.

3.1 Installation notes

Mounting

Pin assignment

The unit can be mounted using the integrated DIN rail mounting option or directly onto
a switch cabinet wall using the four holes integrated into the back wall of the housing. In
the latter case, the two retaining screws for the DIN rail mounting must be removed.
Basically, there are no restrictions regarding positioning in relation to the inverters to be
connected (e.g. MOVITRAC
length and the fact that the UFI11A must be the first or last node on the system bus
(SBus).

The UFI11A must have additional HF-compliant grounding if the DIN rail mounting opti­on is used in conjunction with SBus cables more than 1 m in length.

The UFI11A fieldbus interface is equipped with a 9-pin sub D male connector for the in­coming bus signal and a 9-pin sub D female connector for the outgoing bus signal ac­cording to EN 50170.

As a rule, the fieldbus interface is connected to the INTERBUS system using a twisted,
shielded cable. The shield of the INTERBUS cable must be connected on both ends, for
example on the plug housing. Note the maximum supported transmission rate when you
are selecting the bus connector.

The cable is connected to the INTERBUS plug using pins 6 and 1 (/DO and DO) and
pins 7 and 2 (/DI and DI). Communication takes place via these contacts. The RS-485
signals /DO and DO as well as /DI and DI must have the same contacts on all INTER­BUS stations. Otherwise, communication via the bus will not function.

• Switch on the system bus terminating resistor (S1 2 = ON) of the node end of the sys­tem bus. Switch off the terminating resistor on the other units (S12 = OFF). The
UFI11A fieldbus interface must always be the first or last node on the system bus. It
has an integrated terminating resistor.

• There must not be any potential difference between the units connected to the SBus.
Take suitable measures such as connecting each unit’s ground lug to a central
grounding point in the cabinet to avoid potential differences.

• Point-to-point cabling is not permitted.

24 V connection

Shielding and
routing of the bus
cables

An external 24 VDC voltage supply must be connected to terminals X1:4 and X1:5.

The voltage range for the 24 VDC voltage supply is 18 – 30 V. The current consumption
of the UFI11A fieldbus interface is 300 mA.

The INTERBUS interface supports RS-485 transmission technology and requires the
cable type specified as the physical medium for INTERBUS. This cable must be a shiel­ded, twisted-pair cable with 3 x 2 cores.

Having the bus cable correctly shielded eliminates parasitic interference which can oc­cur in an industrial environment. The following measures ensure the best possible shiel­ding:

• Finter-tighten the retaining screws of plugs, modules and equipotential bonding con­ductors.

• Use only connectors with a metal housing or a metallized housing.

• Maximize the contact area between the shield and the connector housing.

• Shield the bus cable on both ends.

• Do not route the signal and bus cables in parallel with the power cables (motor
leads); use separate cable ducts if possible.

• Only use grounded-metal cable trays in industrial environments.

• Join the signal cables and the associated equipotential bonding together at closely
spaced intervals by the shortest route.

• Avoid using plug connectors to extend bus cables.

• Route the bus cables closely adjacent to available grounding surfaces.

In the event of fluctuations in the ground potential, a compensating current may flow
along the shield which is connected at both ends and to the ground potential (PE). In this
case, make adequate provision for equipotential bonding in accordance with the rele­vant VDE regulations.

Installation and Operation with Autosetup

3.2 Setting the inverter parameters

The settings can be entered using the inverter control panel. Refer to the inverter ope­rating instructions for more information.

• Switch on the voltage supply for the UFI11A and all connected inverters.

• Set an individual SBus address (P813) on the inverters. Recommendation: Assign
the addresses starting from address 1 and working in ascending order according to
the arrangement of inverters in the switch cabinet. Do not assign address 0 since this
is used by the UFI11A.

• Check the SBus baud rate (P816, factory setting = 500 kbaud).

• Set the Setpoint source (P100) to SBus (value 10).

• Set the Control signal source (P101) to SBus (value 3).

• Set the terminal assignment of the binary inputs. The value 0 is recommended for
P60- in MOVITRAC

–DI01 CW/STOP (applied to 24 V, enable CW direction of rotation)
–DI02 CCW/STOP (applied to 24 V, enable CCW direction of rotation)
–DI03 FIX SETPT SW.OV(not connected)
–DI04 n11/n21 (not connected)
–DI05 n12/n22 (not connected)
–Program the unused terminals to "NO FUNCTION" if you are using a MOVIDRIVE

or MOVIDRIVE compact.

• Important: If you need to set P815 SBus timeout delay for MOVITRAC
only possible using a PC. The default value is 0, which means timeout monitoring is
switched off. Set P815 to the value 1 s.

3.3 Autosetup

Switch on the Autosetup function using the DIP switch on the UFI11A. The function is
active for as long as the SYS-FLT LED is flashing briefly with a long interval between
flashes. The LED stays off after the scanning process if at least one inverter has been
detected.
ted by switching the DIP switch off and on again. The SYS-FLT LED remains on follo­wing Autosetup if no inverter is detected. In this case, check the cabling of the SBus, the
terminating resistors of the SBus, the voltage supply to the inverters and the SBus
address settings (P813).

The Autosetup DIP switch must stay switched on.

3.4 Configuration of the fieldbus master

You will find detailed information in the section "INTERBUS interface."

• Set the required process data length via DIP switches 1 ... 5. You will need three pro­cess data words for each drive inverter connected to the UFI11A. That means you
will have to set 9 words in case you are operating three MOVITRAC

on again.

• Start the "CMD Tool" project planning software for your INTERBUS interface.

• Enter the bus setup via "Configuration frame / Read in" or "Read in configuration
frame."

• Assign program addresses of the control program to the INTERBUS process data of
the inverters. This assignment takes place via the context menu "Process data" or
"Process data manager."

• Enhance the control program by the data exchange with the UFI11A.

3.5 Starting the inverters

You can operate up to eight inverters on the INTERBUS via one UFI11A. The INTER­BUS master and the UFI11A will exchange setpoints and actual values of all inverters
connected to the UFI11A in contiguous data packages. It is important for you to know
where a particular inverter is located in the data package (process image). The relation­ship is shown in the following illustration:

5.2 Configuration of the INTERBUS interface

Under the cover plate, there is a DIP switch for setting the INTERBUS data length of the
fieldbus interface. The process data length can be set to a maximum of 24 words using
switches S1-1 to S1-5. The PCP length can be set using switches S1-6 and S1-7. PCP
is the parameter channel of the INTERBUS and is used for setting the parameters of the
UFI11A and the connected inverters.

Fig. 20: UFI11A DIP

switches

The process data channel is the means by which the connected inverters are controlled
and their status read. Since all data of the connected inverters are transmitted by the
INTERBUS, you will have to enter the sum of the process data lengths of all individual
inverters. In Autosetup, this means three words per inverter.

Fig. 21 shows an example setting of six process data words for two inverters. The value
of each switch in determining the process data length is shown on the right.

A maximum of 3PDs can be assigned to one station on the SBus.

The PCP channel can be set to 0, 1, 2, or 4 words. At least one word must be set to
enable parameter data to be exchanged. Higher settings increase the transmission
speed. Fig. 8 shows the possible settings for the PCP channel.

5.4 Control via INTERBUS

Data exchange between the INTERBUS master and the UFI11A takes place using the
I/O area. The process data for all inverters connected to the UFI11A are located in a
contiguous block in this area.

If there is more than one inverter, the associated process data words are appended at
the end (see Fig. 23). The number of process data words per inverter is 3 words with
Autosetup.

The inverters are located in ascending (SBus) address sequence with their associated
process data lengths in the process image, for example an inverter with address 1 and
3 words, then an inverter with address 2 and 3 words, then an inverter with address 3
and 2 words, etc.

5.5 PCP interface

Phone: [phone] - Fax: [phone] - Web: www.clrwtr.com - Email: [e-mail]

The UFI11A fieldbus interface offers a standardized interface for parameter setting
using the "Peripherals Communication Protocol" (PCP). This communications channel
gives you full access to the parameters of the UFI11A fieldbus interface and the drive
parameters of the inverters connected to the UFI11A.

Overview of basic
structure

PCP services

The PCP channel must be set to one, two or four words using the DIP switches on the
UFI11A to enable access to the parameter values of the UFI11A fieldbus interface or the
inverter. Changing the number of PCP words varies the access speed to parameter va­lues via the PCP channel. The PCP interface is implemented using PCP version 3.0 in
the UFI11A.

The UFI11A fieldbus interface supports the PCP services shown in Fig. 10. However,
only the following services are relevant for setting parameters:

• Establishing the connection (Initiate)

• Reading of parameter values (Read)

• Writing of parameter values (Write)

• Cancelling the connection (Abort)

Canceling the

Reading parame­ter values with
"Read"

Writing parameter
values with "Write"

Parameters in the
object list

The "Initiate" PCP service establishes a communication link for exchanging parameters
between an INTERBUS master and the UFI11A fieldbus interface. The connection is al­ways established from the INTERBUS master. Various arrangements relating to the
communication link are checked during establishment of the connection, such as sup­ported PCP services, user data length, etc. The fieldbus interface responds with a posi­tive initiate response if the connection is established successfully. If the connection can
not be established, then the arrangements for the communications link on the INTER­BUS master do not match those on the fieldbus interface. The fieldbus interface re­sponds with an initiate error response. In this case, compare the configured communi­cations relationship list in the INTERBUS master with that in the fieldbus interface.

As a rule, an attempt to re-establish an existing communication link leads to an abort.
The communication link is then dropped, which means the "Initiate" PCP service must
be run a third time in order to re-establish the communication connection.

The "Abort" PCP service cancels an existing communications link between the INTER­BUS master and the fieldbus interface. Abort is an unconfirmed PCP service and can be
triggered either from the INTERBUS master or from the fieldbus interface.

The "Read" PCP service gives the INTERBUS master read access to all communication
objects (drive parameters) of the fieldbus interface. All drive parameters and their coding
are presented in detail in the Fieldbus Unit Profile documentation and the list of MOVID-

®

parameters.

RIVE

The "Write" PCP service gives the INTERBUS master write access to all parameters of
the fieldbus interface. The fieldbus interface generates a write error response if incorrect
access is made to a parameter (e.g. the value written is too large). Precise information
is given relating to the cause of the error.

The "Read" and "Write" PCP services give the INTERBUS master access to all parame­ters defined in the object list of the UFI11A. All the parameters of the fieldbus interface
which can be accessed via the bus system are described as communication objects in
the static object list of the UFI11A. All objects in the static object list are addressed using
indices. The following table shows the structure of the object list of the UFI11A.

The index range is subdivided into three logical areas. The UFI11A parameters are
addressed using indices 8300 – 8313dec. Indices below 8300dec can be used for ac­cessing parameters which are not contained in the object list, or for addressing parame­ters which are found on an inverter connected to the UFI11A.

Object description
of the UFI11A or

The parameters of the connected inverters are described in detail in the SEW document
"Parameter List." In addition to the parameter index, additional information about coding,
the range of values and the meaning of the parameter data is provided. The object de­scription in the object list is identical for all parameters. Even read-only parameters are
given the Read all/Write all attribute in the object list because the inverter undertakes
the corresponding check itself and sends back a return code if necessary. The following
table shows the object description of all parameters.

This object enables you to address all the parameters of the UFI11A itself and the con­nected inverters. The object contains a selection option for the subchannel and address
information for selecting the target unit. It contains information about the data length and
frame type and an acyclical MOVILINK parameter channel. The required service and
data value are specified here. The length is fixed at 12 bytes.

Data Data Data

The subchannel determines to which interface the data will be directed. The setting 0
addresses the parameters of the UFI11A and the subaddress is of no importance. The
setting 1 on the subchannel addresses the standard interface (the SBus in case of the
UFI11A).

The subaddress byte allows selection of the target unit. If you want to address the pa­rameters of a drive inverter connected to the UFI11A via SBus, you will enter the SBus
address of the respective drive inverter.

The frame type must be set to 86hex (only acyclical parameter data). The data length
for this frame type is fixed at 8 bytes.

Variable data
channel performs a
write service

If a write service is performed via the data channel (e.g. write parameter or write para­meter volatile), the UFI11A responds with the current service confirmation when the ser­vice has been performed. The corresponding error code is returned if the write service
is not successful.

This method offers the advantage that the write services are processed simply by sen­ding a WRITE "MOVILINK parameter channel" once and evaluating the "write confirma­tion." The following table shows how write services are performed via the variable data
channel.

Variable data
channel performs a
read type service

A PCP WRITE service has to be performed before a parameter can be read via the data
channel. The PCP WRITE service defines where the UFI11A data should be available.
A read service must take place on the variable data channel in order for these data to
get to the master. As a result, a PCP WRITE and a PCP READ are always required for
performing read services via the variable data channel. The following table shows how
read services are performed via the variable data channel.

INTERBUS Interface

The WRITE service on the "download parameter block" object starts a parameterization
mechanism on the UFI11A. This writes all the parameters specified in the user data area
of the object one after the other in the UFI11A itself or a connected inverter and therefore
sets the parameters of the UFI11A or the inverter. The UFI11A is addressed using
address 0. An inverter connected to the UFI11A is addressed using its SBus address.
The write service is terminated with a positive write response once the download para­meter block has been processed successfully (i.e. all parameters transferred by the IN­TERBUS fieldbus interface have been written). A negative write response is returned in
case of an error. The return code contains more detailed information about the type of
error, as well as the number of the parameter (no. 1 – 38) where the error occurred (see
example).

Write error response for an error when writing the 11th parameter:
Error class: 8 Other
Error code: 0 Other
Additional code high: 11dec Error when writing parameter 11
Additional code low: 15hex Value too large

Note the following points when using the download parameter block:

• Do not perform a factory setting within the download parameter block!

• All parameters written after the parameter lock has been activated will be rejected.

This object is 4 bytes long and, when read access is executed, it returns the numerical
value of the last index which can be addressed directly using the PCP services. PCP
accesses to indices greater than this numerical value must be made using the "MOVI­LINK parameter channel with acyclical routing" object. Access is also possible using ob­ject 8299 "MOVILINK parameter channel acyclical" if the parameters of the UFI11A are
to be addressed.

There are two different procedures involved in setting the drive inverter parameters via
the acyclical MOVILINK parameter channel:

• Parameter channel performs a write service

• Parameter channel performs a read service

If a write service is performed via the acyclical parameter channel (e.g. write parameter
or write parameter volatile), the UFI11A responds with the current service confirmation
when the service has been performed. The appropriate error code is returned if the write
access is not successful.

This method offers the advantage that the write services are processed simply by sen­ding a WRITE "MOVILINK parameter channel" once and evaluating the "write confirma­tion". The following table shows how write services are performed via the acyclical MO­VILINK parameter channel.

Control (master) UFI11A fieldbus interface

1. Initiate the service coded in the parameter channel by means of a WRITE to the "MOVILINK parameter
channel cyclical" object.

WRITE 8299 (parameter channel)

Service confirmation (OK/error code)

The WRITE service coded in the parameter channel is performed and the service con­firmation is returned directly as the response.

Parameter chan­nel performs a
read type service

A PCP WRITE service must be performed before a parameter can be read via the pa­rameter channel. The PCP WRITE service defines where the UFI11A data should be
available. A read service must take place on the acyclical parameter channel in order
for these data to get to the master. As a result, a PCP WRITE and a PCP READ are
always required for performing read services via the parameter channel. The following
table shows how read services are performed via the acyclical MOVILINK parameter
channel.

Control (master) UFI11A fieldbus interface

1. Initiate the service coded in the parameter channel by means of a WRITE to the "MOVILINK parameter
channel cyclical" object.

2. READ "MOVILINK parameter channel cyclical" and evaluation of the service confirmation in the para­meter channel.

WRITE 8299 (parameter channel)

OK

READ 8299 (parameter channel)

Data = Parameter channel with result

1. Reception is confirmed immediately, the parameter channel is evaluated and the re­quested service performed.

2. Service confirmation is entered in the parameter channel and can be evaluated by
READ access in the master.

The acyclical MOVILINK parameter channel is only handled locally on the fieldbus inter­face and is defined as in the following table.

5.6 Return codes for parameter setting

Different return codes will be sent back to the master used for parameter setting in case
of inccorrect parameters. These codes will give the user a detailed insight into the re­ason for an error. The return codes are usually structured according to EN 50170 with
the following elements:

•Error class

•Error code

• Additional code

These return codes apply to all communication interfaces of the UFI11A.

Error class

Error code

The element "Error class" classifies the type of error. The following error classes are
listed according to EN 50170.

Class (hex) Designation Meaning

1 vfd-state Status error of the virtual field device

2 application-reference Error in application program

3 definition Definition error

4 resource Resource error

5 service Error during service execution

6 access Access error

7 ov Error in object directory

8 other Other error (see Additional code)

Except for error class 8 = Other error, the error class is generated by the communication
software of the fieldbus card in case of communication problems. Return codes genera­ted by the inverter system are all classified as error class 8 = Other error. You will get a
more detailed analysis of the error with the element "Additional code."

The element "Error code" gives you more detailed information on the reason for the error
within the "Error class" and is generated by the communication software of the fieldbus
card in case of communication problems. Error code = 0 (other error code) is the only
error code that has been defined for error class 8 = Other error. You will find detailed
information for this error in "Additional code."

cuted once again by turning the switch off and on again. Upon activation of the
Autosetup feature, the UFI11A automatically searches for inverters on the lower-level
SBus and indicates this activity with a brief blinking of the SYS-FLT LED. Each inverter
on the SBus must be assigned a unique SBus address (P813). To avoid confusion with
data assignments, it is recommended to assign the addresses from address 1 ans wor­king in ascending order according to the arrangement of inverters in the control cabinet.
The process image on the fieldbus side will be extended by three words for each located
inverter. The SYS-FLT LED stays on if no inverters are found. A maximum of eight in­verters can be configured. The figure shows the process image for three inverters with
three words in the process output data and process input data. Following the search, the
UFI11A cyclically exchanges three process data words with each connected inverter.
The process output data are collected from the fieldbus, divided into blocks of three and
sent. The process input data are read by the inverters, assembled and sent to the field­bus master.

Autosetup has to be executed only once. The detected configuration will be saved in the
non-volatile memory. See section "Installation and operation without PC."

Important: Execute Autosetup again in case you change the process data assignment
of the inverters connected to the UFI11A, because the UFI11A saves these values once
only during Autosetup. Likewise, the process data assignments (P860 ... P865) of the
connected inverters must not be altered dynamically either, for example by an IPOS pro­gram, following Autosetup.

6 Error Response

6.1 Fieldbus timeout

6.2 SBus timeout

6.3 Unit errors

Error Response

Switching off the fieldbus master or a wire break in the fieldbus cabling leads to a field­bus timeout in the UFI11A. The connected inverters are set to a safe status by zeros
being sent on the process output data. This corresponds to a rapid stop on control word

1. The fieldbus timeout error is self-resetting, meaning the inverters will begin receiving

the current process output data from the master immediately after fieldbus communica­tion is re-established. This error response can be deactivated using P831 on the
UFI11A.

If one or more inverters on the Sbus can no longer be addressed by the UFI11A, the
UFI11A enters error code 91, "System error," in status word 1 of the corresponding in­verter. The SYS-FLT LED lights up and the error is also displayed via the diagnostic in­terface. P815 SBus timeout delay must be set to a value other than 0 on the inverter if
it is to stop. The error is self-resetting on the UFI11A, meaning the current process data
are exchanged again immediately after communication resumes.

UFI11A fieldbus interfaces detect a range of hardware defects and respond with an in­hibit condition. Refer to the list of errors for the exact error responses and measures to
remedy the problem. A hardware defect means error 91 is entered in the process input
data of the fieldbus in status word 1 of all inverters. The SYS-FLT LED on the UFI11A
then flashes evenly. The exact error code is displayed in the status of the UFI11A using
the diagnostic interface of MOVITOOLS.

Application examples

9 Application examples

This section describes small application examples for the exchange of process data and
configuration of the UFI11A or a drive inverter connected to the UFI11A via the PCP in­terface.

9.1 Control via process data

Control of the drive inverters via process data takes place by simple reading/writing of
the program addresses to which the INTERBUS process data of the drive inverters have
been written. A simple STEP7 program for the Simatic S7 looks as follows:

L W#16#0006
T PAW 144 //write 6hex to PO1 (control word = enable)
L 1500
T PAW 146 //write 1500dez to PO2 (speed setpoint = 300 1/min)
L W#16#0000
T PAW 148 //write 0hex to PO3 (has no function after factory setting)

You will find additional information concerning control of the drive inverters via the pro­cess data channel, especially coding of the control and status word, in the manual for
the fieldbus unit profile of the corresponding drive inverter.

9.2 Parameter setting via the PCP interface

This section describes how you can read or write parameters and IPOS variables via the
standardized INTERBUS PCP services "Read" and "Write." The example is valid for all
INTERBUS interface modules of generation 4 (G4) and is explained in the PHOENIX
nomenclature. The coding examples described in the following sections are represented
in the same manner as described in the INTERBUS user manual "Peripherals Commu­nication Protocol (PCP)" published by Phoenix Contact.

Prerequisites

You should have access to the following user manuals:

• INTERBUS user manual "Peripherals Communication Protocol (PCP)", PHOENIX
CONTACT, IBS SYS PCP G4 UM

• Manual for the fieldbus unit profile of the drive inverter connected to the UFI11A

52

Manual – Fieldbus Interface INTERBUS UFI11A

9.3 Representation of the coding examples

Phone: [phone] - Fax: [phone] - Web: www.clrwtr.com - Email: [e-mail]

All information of a PCP service is represented in a word-by-word manner with one word
listed below the other. This means you can consider a word as an PLC word (for examp­le Simatic data word). You will find a coding example for the UFI11A in the right table
column.

Select the UFI11A to be configured with the "Communication Reference (CR)." In the
following examples, the UFI11A has been assigned the CR = 02 hex in the CMD tool.
The index defines the parameter that is to be accessed.

Before you can use the PCP channel of the UFI11A, you will have to configure the de­vice description for the inverter in the CMD Tool.

9.4 Sequence of a parameter setting process

The Peripherals Communication Protocol (PCP) of the INTERBUS standardizes the ac­cess to parameter data of INTERBUS stations and establishes the following sequence:

• Establishing the PCP connection with the "Initiate" service.

• Reading or writing parameters with the "Read" and "Write" services.

• If the communication connection is no longer necessary, it can be disconnected with
the "Abort" service (not explained here since it often is not necessary, see PCP ma­nual).

• Initialization of the PCP connection with the "Initiate" service.

Access to the parameters of the Interbus station takes place only after the PCP connec­tion has been established with "Initiate_Request." This step can be established during
the initial startup of the system.

9.5 Reading of an UFI parameter

You read an UFI11A parameter with the "Read" service. The parameters are typically 4
bytes long (1 double word). This read service accesses only those parameters with in­dices between 8300dez and 8310dez. Parameter access to all other parameters of the
UFI11A or a drive inverter connected to the UFI11A takes place via object 8288 "Vari­able data channel with acyclical routing." The access is decribed in the next section.

9.6 Writing of UFI11A or drive parameters via object 8288

The UFI offers a special parameter access via the object 8288 "variable data channel
with acyclical routing" for the universal write access to all data of the UFI or a drive in­verter connected to the UFI (parameters, IPOS variables, IPOS program code, etc.).
The following description is the mechanism that can be used to change IPOS variables
or other variables via the parameter channel. The "variable data channel with acyclical
routing“ is available via index 8288 dez (2060 hex).

Example

Writing the value 74565 of the IPOS variable H0 = Index 11000 dez (2AF8 hex). The

9.7 Reading of UFI11A or drive parameters via object 8288

The UFI offers a special parameter access via the object 8288 "variable data channel
with acyclical routing" for the universal read access to all data of the UFI or a drive in­verter connected to the UFI (parameters, IPOS variables, IPOS program code, etc.).
The following description is the mechanism that can be used to read the IPOS variables
or other variables via the parameter channel of a drive inverter connected to the UFI
(with SBus address 1). This process requires a two-setp sequence:

• Writing the "variable data channel with acyclical routing“ with the order "Read IPOS
variable H0 to sub channel 1, sub address 1“

• Reading of the "variable data channel with acyclical routing“

The "variable data channel with acyclical routing“ is available via index 8288 dez (2060
hex).

Example

Reading the IPOS variable H0 = Index 11000 dez (2AF8 hex) of the drive inverter with

then one or more stations on the
SBus could not be addressed within
the timeout delay. If the red SYS­FLT LED is flashing, then the
UFI11A itself is in error status. In

An error occurred while the data
record was being copied. The data
are not consistent.

Check the voltage supply and the
SBus cabling, check the SBus ter­minating resistors. Check the con­figuration if the UFI11A was
configured with the PC. Switch the
UFI11A off and on again. Check
the error code using the diagnostic
interface if the error remains, and
take the action described in this
table.

Carry out the "delivery condition"
