2 Introduction

This document describes the features of the Profibus-DP communication module CM-

PDP for the frequency inverter of the series ACT and ACU.

For the Profibus-DP connection, the frequency inverter must be equipped with the

Profibus-DP communication module CM-PDP. The Profibus component CM-PDP is enclosed with the inverter as a separate part and must be fitted by the user. This is extensively described in the chapter "Assembly".

Note:

These instructions are not to be understood as fundamental information on the Profibus-DP. They presuppose underlying knowledge of the methods and modes of effect of the Profibus-DP on the part of the user.

In some points, setting and display possibilities are described alternatively to the control unit KP500 via the VPlus PC program. The operation of a PC with the VPlus program on the frequency inverter with use of the

Profibus component CM-PDP is only possible via an optional interface adapter KP232 on the slot of the keypad.

The Profibus component CM-PDP has the ident number 0x0696 (hexadecimal). The device's data set file has the designation VEC_0696.GSD and is attached to the appendix of this documentation. Identification number and designation of the GSD file have been assigned by the Profibus user organization in Karlsruhe.

Attention! With the help of the Profibus-DP communication module CM-PDP it is possible to access ALL parameters of the frequency inverter from the external control. The control of the access by control levels with the control unit KP500 or the PC software VPlus does not exist. A change of parameters, whose meaning does not admit to the user can lead to the inoperability of the frequency inverter.

3 Assembly of the Profibus-DP communication module CM-PDP

The Profibus component CM-PDP is delivered pre-fitted for assembly in a housing. In addition, a PE spring is enclosed for the PE connection (screening) of the communication module.

Caution! Before the assembly of the Profibus component CM-PDP, the inverter must be switched free of voltage.

Assembly under voltage is not admissible and leads to a destruction of the frequency inverter and / or the Profibus component.

In the first step, the covers are to be removed. After this, the plug-in section for the

Profibus-DP communication module CM-PDP is accessible.

To start with, the supplied PE spring is fitted with the help of the M4 screw in the device. The spring must be aligned centrally.

The Profibus component CM-PDP can now be fitted and screwed onto the PE spring with the M2 screw available on the module.

M4

Caution! The Profibus-DP communication module CM-PDP is pre-fitted in a housing.

The PCB visible on the back may not be touched, as modules can be damaged by this.

After this, the covers have to be fitted again. In the upper cover, the pre-stamped breakthrough for plug X310 is to be broken out and the cover fitted again.

7 Setting PPO type

As a function of the application in question, various objects with differing lengths and contents are used for the exchange of data. The objects PPO1, PPO2, PPO3 and

PPO4 are available. These objects are set up according to the PROFIDRIVE profile.

The required object is to be set on the DP master in the hardware configuration.

There is no setting for the required object on the frequency inverter, it sets itself automatically to the projected object.

Configuration process on the DP master

The configuration process of the frequency inverter with the Profibus communication module CM-PDP is displayed here with the example of a Siemens STEP7 hardware configurator. The process is principally valid for other configurations in an equivalent form.

First, the GSD file VEC_0696.GSD is installed in the hardware configurator (if not already existent). This is done with the menu selection Extras \ Install new GSD.

Here, you enter the path and the name for the GSD file (VEC_0696.GSD).

If the GSD file has been installed, the frequency inverter appears under the selection

PROFIBUS-DP \ Further FIELD DEVICES \ Drives \ ACT 10

From this position, an ACT frequency inverter can now be connected to the required

Profibus phase by Drag & Drop.

The four possible objects PPO1 to PPO4 are now visible under the menu point

ACT 10. The required object is now assigned to the inverter by Drag & Drop.

The screen shot from the STEP7 hardware configuration shows an ACT frequency inverter with the station address 3 and the object PPO2.

8 Commands SYNC / FREEZE

The Profibus component supports the Profibus commands SYNC/UNSYNC and

FREEZE/UNFREEZE. These commands are used to synchronize a number of slaves.

With the FREEZE command, all the slaves keep their input data. They are then read out in sequence by the bus master. As all the slaves keep their inputs simultaneously with the FREEZE command, the bus master is given a process pattern of all the slaves at a defined time. With the UNFREEZE command, this state is canceled and the slaves update their inputs again.

With the SYNC command, all the slaves keep their outputs. Data arriving subsequently are not put through to the outputs, but buffered. The bus master can give new commands to the slaves and activate all the slaves simultaneously with the UNSYNC command. They immediately take over the buffer data to their outputs with the UNSYNC command.

9 Available objects / scanning times

If a Profibus slave has been recognized, parameterized and convalued by its master on the bus, there is a cyclic exchange of data with the DATA_EXCHANGE Profibus service, in which the output data are transmitted from the master to the slave and the input data from the slave to the master in one cycle. The repeat rate with which the slaves carry out the exchange of data with the master, the so-called bus rotation time, is a function of the transmission rate set, the number of subscribers and the size of the objects transmitted. If there are few subscribers, a high transmission rate and short objects being exchanged, bus rotation times of 1 to 2 ms are possible.

As it can be seen from what has just been said that the possible bus rotation time also depends to a considerable extent on the size of the objects to be transmitted, the frequency inverter offers a selection between four different objects PPO1 to PPO4.

In this way, an optimum adaptation to differing situations and requirements is possible.

The objects defined according to PROFIDRIVE principally have two components, which are either completely, partly or not at all existent with the differing objects PPO1 to

PPO4. These components are the communication channel and the process data channel.

communication channel is used for access (write/read) to any parameters in the frequency inverter. An exception is formed by the string parameters, to which there can be no access. The communication proceeds according to a firmly defined hand-shake process and lasts for a number of DATA_EXCHANGE cycles.

process data channel is processed in every cycle. The reference values are accepted and the actual values forwarded. A data update thus takes place with every

DATA_EXCHANGE.

The statement of the consistency describes the parts of the object which must have consistent contents. The consistency states are encrypted in the configuration data of the GSD file and have effects on the possible access mechanisms on the part of the

DP master. In this way, the 8 bytes of the communication channel in a PLC of type

Siemens S7 can only be reached via the special functions SFC14 (DPRD_DAT) and

SFC15 (DPWR_DAT). The words of the process data channel are directly addressable as periphery words (PEW, PAW).

• The communication channel in PPO1 and PPO2 is treated identically.

• The process data channel PZD1 to PZD6 in PPO2 and PPO4 is firmly defined and its contents cannot be altered.

•

The process data channel PZD2 in PPO1 and PPO3 can be altered as regards its contents, controlled via the user-specific bits in the control word STW in the PZD1.

Note:

In the data transmission, the Motorola format is presupposed for the position of Low/High byte front, as is also supported by a PLC of the type

Siemens S7. If the DP master supports the Intel format, Low/High byte are to be swapped on the master side before transmission and after receipt.

Scan time

Regardless of the transmission speed on the Profibus, the scanning time of the inverter is a constant variable as a function of the object used.

PPO3 16 ms

PPO1/2/4 32 ms

An update of the data between the frequency inverter and the Profibus side is done with this scanning time.

PNU: Parameter number (value range 1 to 999)

• The order and reply identifications are stored in the AK area. If no parameter processing is to be done, the "no order" kind of function is to be set.

• With bit 11 (SPM), the readiness for spontaneous report processing can be switched on and off (0 = OFF, 1 = ON, in the present application, the spontaneous report processing is not support, so SPM is always 0).

•

The PNU area transmits the number of the parameter to be processed.

Parameter values (= data) of the type Integer/Unsigned Integer (16 Bit) and Long (32

Bit) can be written and read. The data type is specific in the order identification. In data set change-over capable parameters (array) the required data set is stated under

Parameters, data set selection and cyclic writing

Parameters to be set can be seen from the parameter list referring to the configuration of the standard operating instructions. In the parameter list, state whether a parameter is data set change-over capable (data set/INDEX = 1 to 4) or only exists once

(data set/INDEX = 0).

The parameter list also gives information about the display format of a parameter and its type (int/uint/long). String parameters cannot be transmitted due to the possible number of bytes.

The values transmitted are always integer values. For values with decimal places, the decimal point is not transmitted.

The word IND passes on the required data set of the parameter. In the present application, the parameter set number 0 is simply assigned to existing parameters; a selection from multiple (data set change-over capable) existing parameters is done by inputting a number from 1 to 4.

The actual parameter value is transmitted in the PWE area; as a 16 Bit value (int/uint) it occupies PWEl, as a 32 Bit value (long) PWE high and PWE low, with the high word being in PWE high.

Typically, parameters are addressed via the data set (IND) = 0, 1 to 4. The input of the values is thus done on the controller and automatically into the EEPROM. If values are written cyclically with a higher repeat rate, no entry may be made into the

EEPROM, as the latter only possesses a limited number of admissible writing cycles

(approx. 1 million cycles).

Caution! If the number of admissible writing cycles is exceeded, the EEPROM is destroyed.

To avoid this, cyclically written data can only be transmitted into the RAM without a writing cycle onto the EEPROM. The data are then not stored secure against zero voltage and must be written again after a Power off/on.

This mechanism is activated by the target data set being increased by five in the specification of the data set (IND).

Entry only into the RAM:

Process data channel PZD1/PZD2

In this chapter, the basic functions of the PZD1 and PZD2, which are identical for all the objects PPO1 to PPO4, are described.

10.2.1

PZD1, control word / state word

In PZD1, the master gives its control commands (control word) to the frequency inverter in the output data set and gets the information about its state (state word) in the input data set.

The control of the frequency inverter can be done with three differing operation modes. They are set via the data set change-over capable parameter

412.

412 Local/Remote 0 44 44

For operation on the Profibus, only the settings 0, 1 and 2 are relevant. The further settings relate to the possibilities of control via the KP500 control unit.

Operation mode Function

0 -Control via contacts

The Start and Stop command as well as the statement of the direction of rotation are via digital signals.

The Start and Stop command as well as the statement of the direction of rotation are via the DRIVECOM State machine of the communication interface.

The Start and Stop command as well as the statement of the direction of rotation are via logic signals by the communication protocol.

Control word STW and state word ZSW have differing contents as a function of the operation mode. In each case, all or only some of the bits in the control word are relevant and also only certain feedbacks are possible via the status word. These are then explained in the descriptions of the three possible operation modes.

Control and state word have been created according to DRIVECOM. In this way, there is compatibility to PROFIDRIVE.

Note:

The parameter

Local/Remote

412 is data set change-over capable. Thus, switching over between various operation modes via the data set selection is possible. For example, it is possible to control an frequency inverter via the bus and to activate a local emergency operation if the bus master breaks down. This switch-over is also visible via the state word (Bit Remote).

The data set change-over can be done locally at the frequency inverter via contact inputs or via the bus. For the data set change-over via the bus, the parameter

414 is used.

10.2.2

Control via contacts

In the operation mode control via contacts (

Local/Remote

412 = 0) the frequency inverter is controlled via the contact inputs S2IND to S6IND. The meaning of these inputs can be seen from the operating instructions. The control word in PZD1 is not relevant for this operation mode.

The bit Reference value reached "Bit No. 10" is set when the reference value specified has been reached. In the special case of power failure regulation, the bit is also set if the power failure regulation has reached the frequency 0 Hz (see operating instructions).

In the operation mode control via state machine (Local/Remote 412 = 1) the frequency inverter is controlled via the control word in PZD1. The possible states are shown in the diagram. The values on the transition identify these transitions between the states. The codes shown on the transitions, 0xnn, are the control word needed in each case (Bit 0 to Bit 7). The codes contained in the states, 0xnn, display the contents of the state word (Bit 0 to Bit 7).

After mains on (Reset), the frequency inverter is in the state "Switch-on inhibit“

(0x40). With the transitions 4 and 5, there is a change between "Operation enabled“

Release (transition 4) is only possible if the hardware release is available via contact inputs S1IND/FUF AND (S2IND/STR OR S3IND/STL). They can be firmly wired or also firmly connected to On/Off via the configuration of the digital inputs. If contact input

S1IND/FUF is switched off, the inverter outputs can be blocked at any time. The drive then stops freely. There is a transition to "Ready“ (0x23, power parts blocked).

PZD2, reference value / actual value

In the PZD2, the master gives its reference value to the frequency inverter in the output data set and gets information back about its actual value in the input data set.

The use of the reference/actual value channel is a function of the configuration set

(control system). The actual value is generated from the correct source in question as a function of the control system used.

Note:

The reference value and actual value are referenced to the parameter

The distinction is made via the setting of the parameter

On the basis of the property of the data exchange between master and slave via the

DATA_EXCHANGE service, there must be an evaluation in the state word on the master's side of the actual value available in PZD2. In DATA_EXCHANGE, the output data of the master are written and the input data read in one cycle. The input data are calculated in the previous cycle and temporarily stored in buffers. From these buffers, they are then read in the DATA_EXCHANGE. This is why at least one cycle is necessary in order to switch the actual values over on the device side.

Note:

The displayed "active current" or "torque-forming current" is a function of the control system in question. In field-orientation, the torque-forming current is displayed, in applications with a v/f characteristic control, the active current, which is also a measure for the torque.

The abs. current (r.m.s. current) is always positive. Active current or torque-forming current have a sign in front.

Positive currents = motor

Negative currents = generator operation.

10.2.8

PPO-Out data as global sources

Note:

The functions described in this chapter are available from software version

4.0.5.

In the use of the Profibus-DP, the user has four different objects at his disposal for data transmission between DP master and frequency inverter inverter (see Chapter 9).

Objects PPO2 and PPO4 have output data, which are provided as global data sources in the frequency inverter, in the PZD3 - PZD6.

Communication channel Process data channel

PKE IND PWEh PWEl PZD1 PZD2 PZD3 PZD4 PZD5 PZD6

PPO2

PPO4

This results in new functions for the user, some examples of which are listed here:

• specification of reference value and / or actual value for the technology controller

(as a percentage)

• position commands for digital outputs (as Boolean)

• data set change-over / switch-over fixed frequencies (as Boolean)

• additional reference frequencies (as reference values in Profidrive notation)

• additional reference torques / reference currents for field-oriented applications (as word in internal notation)

As the consistency conditions for the components PZDx have been defined as "consistent via word“ in the object definitions of the GSD file, a direct access by means of

"write periphery word" is possible on the part of the PLC. The application within the

PLC is thus made very simple. The additional benefit is the very quick processing of the PZD channel, with which the applications on the frequency inverter side are provided with permanently updated data.

Note:

For the use of the PPO-Out data as sources for function inputs, it may be necessary, depending on the function used, to load configurationdependent XPI files for the VPlus program, for example swc_111.xpi for configuration 111, technology controller.

The data OUT-PZD3 - 6 in PPO2 and PPO4 are defined as sources. Each of OUT-PZD3

- 6 is a word (16 Bit).

The sources are structured according to the table:

The sources are only available if a CM-PDP communication module exists in the frequency inverter AND the PPO2 or PPO4 is projected as the transmission object.

Each source can only be used once with a specification (Boolean, Word, long).

If the frequency inverter has additionally been equipped with the EM-SYS system bus module, the Profibus sources "OUT-PZDx" can also be transported via the system bus.

The data OUT-PZD3 - 6 can be used as sources for various data types / applications.

Depending on the application, the necessary data format (notation) is to be observed.

They are described below.

Note:

In the data formats on the part of the PLC, the Motorola format (MSB first), as used for example by the Siemens S7, is presupposed.

Boolean data type

The Boolean data type is used for logical functions. In addition, for example, signals such as Clockwise/Anti-clockwise start, data set switch-over or timer inputs can be operated or digital outputs be set directly.

The Word data type can be used for the variables percentage, current and torque.

Current and torque are possible in applications with field-orientation. The scaling in question are described below.

Word data type – Percent

The value range for percentage values is -300.00 to +300.00 %. Display in OUT-PZDn is done with an extension factor of 100.

Set point = -55,36 % OUT-PZDn = 0xEA60 (hexadecimal) = -5536 (decimal)

Word data type – Current

For the current, calculation must be done in the device-internal scaling.

The scaling is:

2

13

Reference value = (Reference current[A] / scaling current[A]) · 2

= 8192 (decimal) = 0x2000 (hexadecimal)

13

Word data type – Torque

For the torque specification, calculation must be done in the device-internal scaling.

The scaling for a torque is identical to the specification of the reference current (see

Current). If the machine is operated with nominal flux, a reference torque corresponds to a reference current.

Note:

The equation stated for current (torque) applies for operation with nominal flux. If a machine is operated in the field weakening area, this is to be considered in the specification values.

If the variables current or torque are used, please regard to the devicespecific scaling.

Note:

The meaning of the content of the OUT-PZDx data and sources is based on the use in question.

If, for example, Boolean variables are to be used, the corresponding entries TRUE/FALSE in the OUT-PZDx objects are to be done on the PLC side. On the device side, only the assigned Boolean sources (750 - 753) are then relevant. The Word and Long sources then do not contain any sensible data.

Any combinations of Boolean, Word and Long can be used. Only pay attention to the assignment of the output objects in the PLC and the assigned sources.

Actual value display of Profibus data

For analysis purposes,

DP-Master OUT

281 and

DP-Master IN

284 are displayed in the data transmitted via the Profibus under the actual value parameters.

The parameters are in the "Actual values \ Actual values frequency inverter" menu point of the VPlus program and can only be looked at with the latter.

In these parameters, the data transmitted via the Profibus are displayed in a processed and comprehensible form. The contents of the process data channel with control word, reference value etc. are permanently updated. As the communication channel has the contents zero in idling and transmission is very quick, the contents of the communication channel are stored on the device side and displayed in the actual value parameters with every transmission.

The displayed content of the communication channel accordingly do not correspond to the current state, but the last transmission.

Note:

The use of the VPlus program with simultaneous use of the Profibus-DP communication module CM-PDP is only possible with the KP232 serial adapter on the slot of the KP500 control unit.

The following diagram shows the display for an object of type PPO2. The contents also apply for the other objects, PPO1, PPO3 and PPO4. In these objects, a part quantity is displayed each time.
