3.3.2 LEDs

The 2 bicolor LEDs in the VLT® PROFIBUS DP MCA 101 indicate the status of PROFIBUS communication.

The LED marked NS (FCD 302: NS2) indicates the network status, that is, the cyclic communication to the PROFIBUS master. When this light is a 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, acyclic DP-V1 communication from either a PROFIBUS master class 1 (PLC) or a master class 2 (MCT 10 Set-up Software, FDT tool). When this light is a 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.

Control Programming Guide

4 Control

4.1 PPO Types

The PROFIBUS prole for frequency converters species a number of communication objects (parameter process data objects, PPO). The PROFIBUS prole for frequency converters is suitable for data exchange between a process controller (for example PLC) and a frequency converter. All PPOs are dened for cyclic data transfer (DP-V0) for transferring process data (PCD) and parameters (PCA) from the master to the slave, and conversely.

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

•

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

PCD 2: The next 2 bytes are

•

entries (see parameter 9-15 PCD Write Congu- ration [1]), but congurable for PCD read entries

(see parameter 9-16 PCD Read Conguration [1]).

PCD 3–10: In the remaining bytes, the process

•

data can be parameterized with process signals, see parameter 9-23 Parameters for Signals.

The setting in parameter 9-15 PCD Write Conguration determines the signals for transmission (request) from the master to the frequency converter.

rst 2 bytes of the process data area

xed for PCD write

The setting in parameter 9-16 PCD Read Conguration determines the signals for transmission (response) from the frequency converter to the master.

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 utilization of I/O and PLC capacity, access parameters via DP-V1. To access via DP-V1, select a pure process data object (PPO type 3, 4, 6, 7, or 8).

Select the PPO type in the master conguration. 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 parameter 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 wordor 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.

Coast stop. Bit 01=0 coast stops and activates the output relay 1 or 2 if the output frequency is 0 Hz, and if [31] Relay 123 is selected in parameter 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 parameter 3-81 Quick Stop Ramp Time.

Bit 02=0 quick stops and activates the output relay 1 or 2 if the output frequency is 0 Hz, and if [31] Relay 123 is selected in parameter 5-40 Function Relay. When bit 02=1, the frequency converter is in state 1, Switching on inhibited.

Refer to Illustration 4.4.

Bit 03, coasting/no coasting

Bit 03=0 leads to a coast stop.

When bit 03=1, if the other start conditions are fullled,

the frequency converter can start.

NOTICE

The selection in parameter 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 parameter 3-81 Quick

Stop Ramp Time.

When bit 04=0, a quick stop occurs.

When bit 04=1, if the other start conditions are fullled,

the frequency converter can start.

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 present output frequency is

maintained, even if the reference value is modied.

When bit 05=1, the frequency converter can perform its

regulating function again according to the respective

reference value.

Bit 06, ramp stop/start

Normal ramp stop using the ramp times of the actual

ramp selected. In addition, if [31] Relay 123 is selected in

parameter 5-40 Function Relay, and if the output frequency

is 0 Hz, this bit activates output relay 01 or 04.

Bit 06=0 stops the frequency converter.

When bit 06=1, if the other start conditions are fullled,

the frequency converter can start.

Synchronize and Freeze

4.6

The control commands sync/unsync and freeze/unfreeze are broadcast functions.

Use sync/unsync to synchronize control commands and/or speed reference to all the connected frequency converters.

Use freeze/unfreeze to freeze the status feedback in the slaves to obtain synchronized feedback from all connected slaves.

4.6.1 Sync/Unsync

To obtain simultaneous reactions such as synchronized start, stop, or speed change in several slaves, use sync/ unsync. 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 an unsync command is received. An unsync command stops the synchronization mechanism and enables normal DP data exchange.

Control

VLT® PROFIBUS DP MCA 101

4.6.2 Freeze/Unfreeze

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.

At the receipt of an unfreeze command, the values once again are continuously updated and the slave returns a present value, for example a value generated by current conditions.

The values are updated when a new freeze or unfreeze command is received.

Parameter Access Programming Guide

5 Parameter Access

5.1 Parameter Access in General

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.

Parameter access from controllers and HMI

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 wanted set-up in parameter 0-11 Edit Set-up or parameter 9-70 Edit Set-up.

Using the above-mentioned mechanism allows reading or writing to and from parameters in a certain set-up from a master class 1, for example a PLC. It is also possible to access parameters simultaneously in a 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:

Although the parameter channels are separated, data conict can occur when writing to parameters from an HMI unit into a set-up actively in use by the frequency converter or the process controller (for example a PLC).

5.1.1 Data Store

5.1.2 Read/Write in Double Word Format

The special request IDs 0X51 (read) and 0X52 (write) allow reading and writing to all parameters containing numeric values in a general format of double word. The value element must be right-aligned and unused MSBs lled 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 signaled by the telegram is 43h (dword).

5.1.3 PROFIBUS DP-V1

The acyclic DP-V1 transmission allows reading and writing parameter values, as well as reading a number of descriptive attributes for each parameter. Access to parameters via DP-V1 is described in chapter 5.2 DP-V1 Parameter Access.

5.1.4 PROFIBUS DP V0/PCV Channel

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.

NOTICE

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

5 5

Parameters write via the PCV channel (DP V0) is stored in RAM only. If data has to be stored in non-volatile memory, use parameter 9-71 Probus Save Data Values for storing 1 or more set-ups.

Using DP-V1 access, store parameters either in RAM or non-volatile memory by selecting a specic write-request command. At any time, store non-stored data in nonvolatile memory by activating parameter 9-71 Probus Save Data Values.

5.2.1 PROFIBUS DP-V1 Introduction

The PROFIBUS DP extension DP-V1 oers acyclic communication in addition to the cyclic 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).

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

Acyclic communication is a used for read/write from and to parameters from process controllers, PC-based tools, or monitoring systems.

5.2.2 Features of a Master Class 1 Connection

Cyclic data exchange (DP-V0).

•

Acyclic 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, and so on. The master class 1 acyclic connection can be used for general parameter access in the slaves. However, the acyclic connection is xed and cannot be changed during operation.

5.2.5 Principle of Data Exchange by PROFIBUS DP-V1

In a DP cycle, the master class 1 (MC1) rst updates the cyclic process data for all slaves in the system. The MC1 then sends 1 acyclic message to 1 slave. If a master class 2 (MC2) is connected, the MC1 hands over the bus rights to MC2. MC2 is then allowed to send 1 acyclic message to 1 slave. The token is then handed back to the MC1, and a new DP cycle begins.

5.2.3 Features of a Master Class 2 Connection

Initiate/abort acyclic connection.

•

Acyclic read/write from and to parameters.

•

The master class 2 acyclic connection is typically used for conguration or commissioning tools for easy access to each parameter in any slave in the system. The acyclic connection can be dynamically established (initiated) or removed (aborted) even when a master class 1 is active on the network.

5.2.6 DP-V1 Features for Parameter Access

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

The standard PROFIBUS DP-V1 read and write services are not sucient for accessing the many parameters and attributes in the frequency converter. For this reason, the PROFIdrive parameter channel is dened. 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.

For a detailed description of the DP-V1 command handling, refer to the PROFIBUS DP-V1 Design Guide.

The DP-V1 parameter response telegram consists of 2 data blocks:

A response header, which indicates:

•

- If the request is performed without

errors (response ID).

- The number of parameters.

- The request reference set by the master

within the corresponding request.

A data eld, where the requested data are placed.

PCD reference parameter

Process data may be scaled by a parameter, for example the maximum 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. Therefore the process data must deliver a reference to parameter X.

Field PCD normalization

The eld PCD normalization must express the value that shows the 100%. Thus, the normalization delivered back must be the set bit 15 and a value of 0xe (14, 2

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 parameter 3-41 Ramp 1

Ramp Up Time covers a long word (32 bits). Parameter 3-41 Ramp 1 Ramp Up Time = 155 hex: In this

example, bytes 1 and 2 are set to 3155. See the values for bytes 1 and 2 in chapter 5.3.5 Example.

IND (bytes 3–4)

Used when reading/changing parameters with subindex, for example parameter 9-15 PCD Write Conguration. In the example, bytes 3 and 4 are set to 00 hex. See the values for bytes 3 and 4 in chapter 5.3.5 Example.

PVA (bytes 5–8)

Change the data value of parameter 3-41 Ramp 1 Ramp Up Time to 10.00 s. The value transmitted must be 1000, because the conversion index for parameter 3-41 Ramp 1 Ramp Up Time is 2. Therefore, 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 Parameter

and Data Type. See the values for bytes 5–8 in chapter 5.3.5 Example.

These values are for bytes 9 and 10 in chapter 5.3.5 Example. Quick stop: 0000 0100 0110 1111=046F hex. Stop: 0000 0100 0011 1111=043F hex.

6.1 8-** PROFIBUS Parameters

This chapter describes the general parameters relating to PROFIBUS and the communication settings of the frequency converter.

Not all product series support all parameters, just as the parameter settings may vary between the product series. For details of the parameters in parameter groups 8-**

Comm. and Options, 9-** PROFIBUS, and 16-** Data Readouts, refer to the programming guide of the

specic

product series.

Control by using control word only.

8-02 Control Word Source

Option: Function:

NOTICE

This parameter cannot be adjusted while the motor is running.

Select the source of the control word: 1 of 2

serial interfaces or 4 installed options. During

initial power-up, the frequency converter

automatically sets this parameter to [3] Option

A if it detects a valid

in slot A. When the option is removed, the

frequency converter detects a conguration

change, sets parameter 8-02 Control Word

Source to default setting [1] FC RS485, 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

shows: Alarm 67, Option Changed.

When retrotting a bus option into a

frequency converter that did not have a bus

option installed earlier, change the control to

bus-based. This change is required for safety

reasons to avoid an unintended change.

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 extra words, which can be programmed to monitor process signals:

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 allowed 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.

Troubleshooting Programming Guide

8 Troubleshooting

8.1 Diagnosis

VLT® PROFIBUS DP MCA 101 provides a exible way of performing diagnosis of slave units, based on diagnosis messages.

During normal cyclic 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-specic, diagnosis information. The standard diagnosis messages cover a limited range of general diagnosis possibilities, whereas the extended diagnosis function oers detailed messaging specic to the frequency converter.

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

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.

8.2 No Response to Control Signals

Check that:

The control word is valid.

•

When bit 10=0 in the control word, the frequency converter does not accept the control word. The default setting is bit 10=1. Set bit 10=1 via the PLC.

The relationship between bits in the control word

•

and the terminal I/Os is correct. Check the logical relationship in the frequency converter. Set the logic to bit 3=1 and digital input=1 to achieve a successful start.

Select the FC control mode, digital input, and/or serial communication, using parameter 8-50 Coasting Select to parameter 8-56 Preset Reference Select.

Fault Messages via DP Diagnosis

8.4

The standard DP function features an online diagnosis, which is active during DP initialization and data exchange mode.

Troubleshooting Programming Guide

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 is sent regardless of whether it appears in the frequency converter or not.

When parameter 8-07 Diagnosis Trigger is set to [1]

•

Alarms, extended diagnosis data is sent when 1 or more alarms arrive in the alarm

parameter 16-90 Alarm Word or parameter 9-53 Probus Warning Word.

When parameter 8-06 Reset Control Word Timeout is set to [2] Alarms/Warnings, extended diagnosis data is sent if 1 or

more alarms/warnings arrive in the alarm

parameter 16-90 Alarm Word or parameter 9-53 Warning Word, or in the warning parameter 16-92 Warning Word.

The extended diagnosis sequence is as follows: If an alarm or warning appears, the frequency converter sends a high-priority message to the master via the output data telegram. The master then sends a request for extended diagnosis information, to which the frequency converter replies. When the alarm or warning disappears, the frequency converter again sends a message to the master, and on the following request from the master, returns a standard DP diagnosis frame (6 bytes).
