Configure the Frequency Converter

3.3.1 Frequency Converter Parameters

The following parameters are important when configuring the frequency converter with a PROFIBUS interface:

3.3.2 LEDs

The 2 bi-colour LEDs in the PROFIBUS card indicate the status of PROFIBUS communication.

The LED marked NS (FCD 302: NS2) indicates the network status, that is, the cyclical communication to the PROFIBUS master. When this light is constant green, data exchange between the master and the frequency converter is active.

The LED marked MS (FCD 302: BUS MS) indicates the module status, that is, acyclical DP V1 communication from either a PROFIBUS master class 1 (PLC) or a master class 2 (MCT 10, FDT tool). When this light is constant green, DP V1 communication from master classes 1 and 2 is active.

For details of the full range of communications status indicated by the LEDs, refer to chapter 8 Troubleshooting.

4.1 PPO Types

The PROFIBUS profile for frequency converters specifies a number of communication objects (Parameter process data objects, PPO). The PROFIBUS profile for frequency converters is suitable for data exchange between a process controller (for example PLC) and a frequency converter. All PPOs are defined for cyclic data transfer (that is, DP V0), so that process data (PCD) and parameters (PCA) can be transferred from the master to the follower and vice versa.

Pure process data objects

PPO types 3, 4, 6, 7 and 8 are pure process data objects for applications requiring no cyclic parameter access. The PLC sends out process control data, and the frequency converter then responds with a PPO of the same length, containing process status data.

Illustration 4.1 shows the available PPO types:

PCD 1: The first 2 bytes of the process data area

•

(PCD 1) comprise a fixed part present in all PPO types.

PCD 2: The next 2 bytes (PCD 2) are fixed for PCD

•

write entries (see parameter 9-15 PCD Write Configuration [1]), but configurable for PCD read entries (see parameter 9-16 PCD Read Configuration [1]).

PCD 3-10: In the remaining bytes, from PCD 3

•

and on, the process data can be parameterised with process signals, see parameter 9-23 Parameters for Signals.

The signals for transmission from the master to the frequency converter are determined by the setting in parameter 9-15 PCD Write Configuration (request from master to the frequency converter).

The signals for transmission from the frequency converter to the master (response from the frequency converter to master) are determined by the setting in parameter 9-16 PCD Read Configuration .

Parameter channel and process data

PPO types 1, 2 and 5 consist of a parameter channel and process data. Use the parameter channel for reading and/or updating of parameters (successively). Alternatively, for better utilisation of I/O and thus PLC capacity, access parameters via DP V1, by selecting a pure process data object (PPO type 3, 4, 6, 7 or 8).

Select the PPO type in the master configuration. The selection is automatically recorded in the frequency converter. No manual setting of PPO types in the frequency converter is required. Read the current PPO type in 9-22 Telegram Selection. The setting [1] Standard telegram 1 is equivalent to PPO type 3.

In addition, all PPO types can be set up as word-consistent or module-consistent. The process data area can be word or module consistent, whereas the parameter channel must always be module consistent.

Word-consistent data is transmitted as individual

•

independent words between the PLC and the frequency converter.

Module-consistent data is transmitted as sets of

•

interrelated words transferred simultaneously between the PLC and the frequency converter.

control of the frequency converter in 8-50 Coasting Select to 8-56 Preset Reference Select.

NOTICE

The setting of 8-01 Control Site overrules the settings in 8-50 Coasting Select to 8-56 Preset Reference Select. The

setting of terminal 37 Coast stop (safe) overrules any other parameter.

Each of the digital input signals can be programmed to logic AND, logic OR, or to have no relation to the corresponding bit in the control word. In this way the following signal sources initiate a specific control command, for example stop/coast:

fieldbus only,

•

fieldbus AND digital input, or

•

either fieldbus OR digital input terminal.

•

CAUTION

To control the frequency converter via PROFIBUS, set 8-50 Coasting Select to either [1] Bus , or to [2] Logic AND, and set 8-01 Control Site to [0] or [2].

For more detailed information and examples of logical relationship options, see chapter 8 Troubleshooting.

Table 4.5 Control Word Bits

Explanation of the control bits Bit 00, OFF 1/ON 1

Normal ramp stops using the ramp times of the actual selected ramp. Bit 00="0" leads to the stop and activation of the output relay 1 or 2 if the output frequency is 0 Hz and if [Relay 123] has been selected in 5-40 Function Relay. When bit 0="1", the frequency converter is in State 1: “Switching on inhibited”. Refer to Illustration 4.4.

Bit 01, OFF 2/ON 2

Coasting stop. When bit 01="0", a coasting stop and activation of the output relay 1 or 2 occurs if the output frequency is 0 Hz and if [Relay 123] has been selected in 5-40 Function Relay. When bit 01="1", the frequency converter is in State 1: “Switching on inhibited”. Refer to Illustration 4.4.

Bit 02, OFF 3/ON 3

Quick stop using the ramp time of 3-81 Quick Stop Ramp Time.

When bit 02="0", a quick stop and activation of the output relay 1 or 2 occurs if the output frequency is 0 Hz and if [Relay 123] has been selected in 5-40 Function Relay. When bit 02="1", the frequency converter is in State 1: “Switching on inhibited”.

Control Programming Guide

Refer to Illustration 4.4.

Bit 03, Coasting/No coasting

Coasting stop Bit 03="0" leads to a stop. When bit 03="1", the frequency converter can start if the other start conditions are fulfilled.

NOTICE

The selection in 8-50 Coasting Select determines how bit 03 is linked with the corresponding function of the digital inputs.

Bit 04, Quick stop/Ramp

Quick stop using the ramp time of 3-81 Quick Stop Ramp Time.

When bit 04="0", a quick stop occurs. When bit 04="1", the frequency converter can start if the other start conditions are fulfilled.

NOTICE

The selection in parameter 8-51 Quick Stop Select determines how bit 04 is linked with the corresponding function of the digital inputs.

Bit 05, Hold frequency output/Use ramp

When bit 05="0", the current output frequency is being maintained even if the reference value is modified. When bit 05="1", the frequency converter can perform its regulating function again; operation occurs according to the respective reference value.

Bit 06, Ramp stop/Start

Normal ramp stop using the ramp times of the actual ramp as selected. In addition, activation of the output relay 01 or 04 if the output frequency is 0 Hz if Relay 123 has been selected in 5-40 Function Relay. Bit 06="0" leads to a stop. When bit 06="1", the frequency converter can start if the other start conditions are fulfilled.

NOTICE

The selection in 8-53 Start Select determines how bit 06 is linked with the corresponding function of the digital inputs.

Bit 07, No function/Reset

Reset after switching off. Acknowledges event in fault buffer. When bit 07="0", no reset occurs. When there is a slope change of bit 07 to "1", a reset occurs after switching off.

Bit 08, Jog 1 OFF/ON

Activation of the pre-programmed speed in 8-90 Bus Jog 1 Speed. JOG 1 is only possible if bit 04="0" and bit

00-03="1".

Bit 09, Jog 2 OFF/ON

Activation of the pre-programmed speed in 8-91 Bus Jog 2 Speed. JOG 2 is only possible if bit 04="0" and bit

00-03="1".

Bit 10, Data invalid/valid

Used to tell the frequency converter whether the control word is to be used or ignored. Bit 10=“0” causes the control word to be ignored, giving the opportunity to turn off the control word when updating/reading parameters. Bit 10=“1” causes the control word to be used. This function is relevant, because the control word is always contained in the telegram, regardless of which type of telegram is used.

Bit 11, No function/Slow down

Used to reduce the speed reference value by the amount given in 3-12 Catch up/slow Down Value value. When bit 11="0", no modification of the reference value occurs. When bit 11="1", the reference value is reduced.

Bit 12, No function/Catch up

Used to increase the speed reference value by the amount given in 3-12 Catch up/slow Down Value. When bit 12="0", no modification of the reference value occurs. When bit 12="1", the reference value is increased. If both slowing down and accelerating are activated (bit 11 and 12="1"), slowing down has priority, and the speed reference value is reduced.

Bits 13/14, Set-up selection

Bits 13 and 14 are used to select between the 4 parameter set-ups according to Table 4.6.

The function is only possible if Multi Set-up has been selected in 0-10 Active Set-up.

SYNC/UNSYNC is used to synchronise control commands and/or speed reference to all the connected frequency converters.

FREEZE/UNFREEZE is used to freeze the status feedback in the slaves to get synchronized feedback from all connected slaves.

The synchronise and freeze commands affect only process data (the PCD part of the PPO).

4.6.1 SYNC/UNSYNC

SYNC/UNSYNC can be used to obtain simultaneous reactions in several slaves, for example synchronised start, stop or speed change. A SYNC command freezes the relevant control word and speed reference. Incoming process data are stored but not used until a new SYNC command or a UNSYNC command is received. An UNSYNC command stops the synchronisation mechanism and enables normal DP data exchange.

FREEZE/UNFREEZE

4.6.2

FREEZE/UNFREEZE can be used for simultaneous reading of process data, for example, output current, from several slaves.

A FREEZE command freezes the actual values and upon request the slave sends back the value that was present when the FREEZE command was received.

Upon receipt of an UNFREEZE command the values once again is continuously updated and the slave returns a present value, for example, a value generated by conditions at present time.

The values is updated when a new FREEZE or UNFREEZE command is received.

4.6

Synchronise and Freeze

The control commands SYNC/UNSYNC and FREEZE/ UNFREEZE are broadcast functions.

Parameter Access

5 Parameter Access

5.1 Parameter Access in General

Programming Guide

5.1.2

Read/Write in Double Word Format

In an automated system, frequency converter parameters can be accessed either from the process controller (that is, PLC), or from various kinds of HMI equipment. For parameter access from controllers and HMI, observe the following:

Parameters are located in 4 separate set-ups. Parameter access in the frequency converter is performed via several separated parameter channels. Use the separated channels individually to access a certain parameter set-up. Select the desired set-up in 0-11 Edit Set-up or 9-70 Edit Set-up.

Using the above mechanism it is possible to read or write to and from parameters in a certain set-up from a master class 1, for example a PLC. And it is also possible to simultaneously access parameters in a different set-up from a master class 2, for example a PC tool, without interfering with the set-up selection for the programming sources.

Parameters can be accessed via the following sites:

LCP

•

FC Protocol on RS485 or USB

•

Cyclical data access on DP-V0 (PCV Channel)

•

PROFIBUS Master Class 1

•

PROFIBUS Master Class 2 (3 connections possible)

•

Using the special request IDs 0X51 (read) and 0X52 (write), it is possible to read and write to all parameters containing numeric values in a general format of double word. The value element must be right aligned and unused MSBs filled with zeros.

Example: Read of a parameter of type U8 is transmitted as 00 00 00 xx, where xx is the value to be transmitted. The data type signalled by the telegram is 43h (dword).

5.1.3 PROFIBUS DP-V1

Using the acyclic DP-V1 transmission, it is possible to read and write parameter values, as well as to read a number of descriptive attributes for each parameter. Access to parameters via DP-V1 is described in chapter 5.2 DP-V1 Parameter Access.

PROFIBUS DP-V0/PCV Channel

5.1.4

Parameter access via the PCV channel is performed using PROFIBUS DP-V0 cyclic data exchange, where the PCV channel is part of the PPOs described in chapter 4.1 PPO Types. Using the PCV channel, it is possible to read and write parameter values, as well as read a number of descriptive attributes for each parameter. The functionality of the PCV channel is described in chapter 5.3 PCV Parameter Access.

5 5

NOTICE

Although the parameter channels are separated, data conflict can occur if write to parameters is made from an HMI unit into a set-up which is actively in use by the frequency converter or the process controller (e.g. a PLC).

5.1.1 Data Store

Parameters write via the PCV channel (DP-V0) is stored in RAM only. If data has to be stored in non-volatile memory, the 9-71 Profibus Save Data Values can be used for storing one or more set-ups.

Using DP-V1 access, store parameters either in RAM or non-volatile memory by choice of a specific write-request command. At any time, store non-stored data in nonvolatile memory by activating 9-71 Profibus Save Data Values.

NOTICE

Object and data types common to both DP-V1 and PCV parameter access are listed in chapter 5 Parameter Access.

5.2 DP-V1 Parameter Access

This section is useful for the developer with some experience in:

PLC programs with PROFIBUS master class 1

•

functionality. PC applications with PROFIBUS master class 2

•

5.2.1 PROFIBUS DP-V1 Introduction

5.2.5

Principle of Data Exchange by PROFIBUS DP-V1

The PROFIBUS DP extension DP-V1 offers acyclical communication in addition to the cyclical data communication of DP-V0. This feature is possible using a DP master class 1 (for example, PLC), as well as a DP master class 2 (for example, PC Tool).

Cyclical communication means that data transfer takes place continuously with a certain refresh rate. This is the known DP-V0 function normally used for quick update of I/O process data.

In a DP cycle, the master class 1 (MC1) first updates the cyclical process data for all slaves in the system. The MC1 then sends one acyclical message to one slave. If a master class 2 (MC2) is connected, the MC1 hands over the bus rights to MC2, which is then permitted to send one acyclical message to one slave. The token is then handed back to the MC1, and a new DP cycle begins.

Acyclical communication takes the form of a once-off data transfer event, mainly used for read/write from and to parameters from process controllers, PC-based tools or monitoring systems.

Features of a Master Class 1

5.2.2 Connection

Cyclical data exchange (DP-V0)

•

Acyclical read/write from and to parameters

•

A master class 1 is used as the process controller (either PLC or PC-based), responsible for commands, speed reference, status of the application, etc. The master class 1 acyclical connection can be used for general parameter access in the slaves. However, the acyclical connection is fixed, and cannot be changed during operation.

Features of a Master Class 2

5.2.3 Connection

Initiate/abort acyclical connection

•

Acyclical read/write from and to parameters

•

The master class 2 acyclical connection is typically used for configuration or commissioning tools for easy access to each parameter in any slave in the system. The acyclical connection can be dynamically established (initiate) or removed (abort) even when a master class 1 is active on the network.

This section describes how to use DP-V1 for accessing VLT parameters.

The standard PROFIBUS DP-V1 read and write services are not sufficient for accessing the many parameters and attributes in the frequency converter. For this reason, the PROFIdrive parameter channel is defined. Using this parameter read/write is performed by addressing a single DP-V1 object in the frequency converter as shown in the example, Table 5.3.

PCD reference parameter

Process data may be scaled by a parameter, for example, the max reference of 0x4000 (in %) depends on the setting of parameter X. To enable the master to calculate the real value of the process data, it has to know the value of parameter X, and therefore the process data must deliver a reference to parameter X.

Field PCD normalisation

The field PCD normalization must express, in any case, the value that represents the 100%, that is, the normalization delivered back must be the set bit 15 and a value of 0xe (14, 214 =0x4000), and the result must be 0x800e.

For some frequency converter parameters a descriptive text is available, which can be read using this attribute. The availability of a text description for a parameter is indicated by a bit set in the identifier (ID) parameter description element, which can be read out by the description attribute (20H) sub-index=1. If bit 10 is set, a descriptive text exists for each value of the parameter. As an example, 0-01 Language has settings from 0 to 5. For each of these values a specific text exists: 0=English, 2=Deutsch, and so on.

PCA parameter characteristics

PCA part (byte 1-2). The RC part tells what the PCV part must be used for. The functions available are listed in chapter 5.3.1 PCA Handling.

When a parameter is changed, select value 2 or 3. In this example, 3 is selected, because 3-41 Ramp 1 Ramp Up Time covers a long word (32 bits). 3-41 Ramp 1 Ramp Up Time=155 hex: In this example, byte 1 and 2 are set to 3155. See the values for bytes 1 and 2 in Table 5.18.

PVA (bytes 5-8)

The data value of 3-41 Ramp 1 Ramp Up Time must be changed to 10.00 s. The value transmitted must be 1000, because the conversion index for 3-41 Ramp 1 Ramp Up Time is 2. This means that the value received by the frequency converter is divided by 100, such that the frequency converter perceives 1000 as 10.00. Bytes 5-8=1000=03E8 hex. See chapter 5.4 PROFIBUS DP

When the option is removed, the frequency converter detects a configuration change, sets parameter 8-02 Control Word Source back to default setting RS-485, and trips. If an option is installed after initial power-up, the setting of parameter 8-02 Control Word Source does not change, but the frequency converter trips and displays: Alarm 67 Option Changed. When retrofitting a bus option into a frequency converter that did not have a bus option installed to begin with, take an active decision to move the control to bus-based.

7.1 Example 1: Process Data with PPO Type 6

This example shows how to work with PPO type 6, which consists of control word/status Word and reference/main actual value. The PPO also has 2 additional words, which can be programmed to monitor process signals:

STW MAV

The application requires monitoring of the motor torque and digital input, so PCD 3 is set up to read the current motor torque. PCD 4 is set up to monitor the state of an external sensor via the process signal digital input. The sensor is connected to digital input 18.

An external device is also controlled via control word bit 11 and the built-in relay of the frequency converter. Reversing is permitted only when the reversing bit 15 in the control word and the digital input 19 are set to high.

For safety reasons the frequency converter stops the motor if:

The PROFIBUS cable is broken.

•

The master has a system failure.

•

The PLC is in stop mode.

8.1 Diagnosis

PROFIBUS-DP provides a flexible way of performing diagnosis of slave units, based on diagnosis messages.

During normal cyclical data exchange:

1. The slave sets a diagnosis bit, which requests the master to send a diagnosis message during the next scan cycle, instead of the normal data exchange.

2. The slave answers the master with a diagnosis message consisting of standard diagnosis information, 6 bytes, and possibly extended, vendor specific, diagnosis information. The standard diagnosis messages cover a limited range of general diagnosis possibilities, whereas the extended diagnosis function offers detailed

See chapter 8.3 Warnings and Alarms for the extended diagnosis messages for the frequency converter. A master or a network analysing tool is able to translate these diagnosis words into real text messages using the GSD-file.

messaging specific to the frequency converter.

NOTICE

DP V1 diagnosis is supported for PROFIBUS SW version

2.X and later versions. The default setting of the PROFIBUS option is DP V1 diagnosis. When DP V0 diagnosis is required, change the setting under DP slave Properties.

8.5 Extended Diagnosis

Receive the extended diagnosis function, alarm and warning information from the frequency converter. The setting of parameter 8-07 Diagnosis Trigger determines which frequency converter events trigger the extended diagnosis function:

When parameter 8-07 Diagnosis Trigger is set to

•

[0] Disable, no extended diagnosis data are sent regardless of whether they appear in the frequency converter.

When parameter 8-07 Diagnosis Trigger is set to

•

[1] Alarms, extended diagnosis data are sent when one or more alarms arrive in the alarm 16-90 Alarm Word or 9-53 Profibus Warning Word.

When parameter 8-06 Reset Control Word Timeout is set to [2] Alarms/Warnings, extended diagnosis data are sent if 1 or more alarms/warnings arrive in the alarm 16-90 Alarm Word or 9-53 Profibus Warning Word, or in the warning

16-92 Warning Word.

The extended diagnosis sequence is as follows: If an alarm or warning appears, the frequency converter indicates that to the master by sending a high priority message via the output data telegram. This causes the master to send a request for extended diagnosis information to the frequency converter, to which the frequency converter replies. When the alarm or warning disappears, the frequency converter again indicates that to the master, and on the following request from the master,
