Safety and operating instructions for drive power converters
(as per: Low Voltage Directive 2006/95/EEC )
1. General
During operation, drive power converters may, depending on their protection class, have live, bare, moving or rotating parts or hot surfaces.
Unauthorised removal of covers, improper use, incorrect installation or operation causes a risk of serious personal injury or material damage.
Further information can be found in this documentation. All transportation, installation and initialisation and maintenance work
must be carried out by qualified personnel (comply with IEC 364, CENELEC HD 384, DIN VDE 0100, IEC 664 and DIN VDE 0110, and national accident prevention regulations).
For the purposes of these basic safety instructions, qualified personnel are persons who are familiar with the assembly, installation, commissioning and operation of this product and who have the relevant qualifications for their work.
2. Proper use in Europe
Drive power converters are components intended for installation in electrical systems or machines.
When installed in machines, the drive power converter cannot be commissioned (i.e. commencement of the proper use) until it has been ensured that the machine meets the provisions of the EC Directive 2006/42/EEC (machine directive); EN 60204 must also be complied with.
Commissioning (i.e. implementation of the proper use) is only permitted when the EMC directive (2004/108/EEC) is complied with.
Drive power converters with the CE mark meet the requirements of the Low Voltage Directive 2006/95/EEC. The harmonized standards stated in the Declaration of Conformity are used for the drive power converters.
Technical data and information for connection conditions can be found on the rating plate and in the documentation, and must be complied with.
The drive power converters may only be used for the safety functions which are described and for which they have been explicitly approved.
3. Transport, storage
Information regarding transport, storage and correct handling must be complied with.
4. Installation
The installation and cooling of the equipment must be implemented according to the regulations in the corresponding documentation.
The drive power converter must be protected against impermissible loads. Especially during transport and handling, components must not be deformed and/or insulation distances must not be changed. Touching of electronic components and contacts must be avoided.
Drive power converters have electrostatically sensitive components, which can be easily damaged by incorrect handling. Electrical components must not be mechanically damaged or destroyed (this may cause a health hazard!).
5. Electrical connections
When working on live drive power converters, the applicable national accident prevention regulations must be complied with (e.g. VBG A3, formerly VBG 4).
The electrical installation must be implemented according to the applicable regulations (e.g. cable cross-section, fuses, ground lead connections). Further instructions can be found in the documentation.
Information about EMC-compliant installation – such as shielding, earthing, location of filters and installation of cables can be found in the drive power converter documentation. These instructions must be complied with even with CE marked drive power converters. Compliance with the limiting values specified in the EMC regulations is the responsibility of the manufacturer of the system or machine.
6. Operation
Where necessary, systems where drive power converters are installed must be equipped with additional monitoring and protective equipment according to the applicable safety requirements, e.g. legislation concerning technical equipment, accident prevention regulations, etc.
The parameterisation and configuration of the drive power converter must be selected so that no hazards can occur.
All covers must be kept closed during operation.
7. Maintenance and repairs
After the drive power converter is disconnected from the power supply, live equipment components and power connections should not be touched immediately, because of possible charged capacitors. Observe the relevant information signs located on the drive power converter.
Further information can be found in this documentation.
These safety instructions must be kept in a safe place!

2.1.1 SK 2xxE hardware configurator

Fig. 1: Hardware configuration - Integration of NORD module [SK 2xxE] to PROFIBUS
After integration into the network (Figure above) a dialogue window opens in the hardware configurator (Figure below). Entries must be made in this window. The selected GSD file is displayed in the General tab in the "order number" field and therefore the correct selection can be checked. The quickest method of finding the GSD files is to use the search entry "NORD" at the top right of the hardware configurator catalogue.
2 Step 7 hardware configurator
A slave address and a diagnostic address must be assigned. For further documentation, the station can be assigned a more precise designation of the station name for the application.

S7 standard modules – Supplementary manual options for NORD - Frequency Inverters
Note
If "DP-Alarm-Mode" is set on the slave, the operating mode of the DP-Master must be set to "DPV1" under DPMode.
In addition, in the tab Parameterise of the properties window (Figure below), the "DP-Alarm-Mode" of the DP slave must be set to "DPV1", whereby this setting is only necessary if the frequency inverter is to be accessed in acyclic mode.

3. Process modules

Process modules are only used to control a frequency inverter. No parameters are changed. Parameter changes are only performed by the use of other measures. If parameter values from the Step 7 program are to be changed, the appropriate parameter modules must be used. Call-up of the process modules is carried out in the cyclic program.

3.1 Purpose of the process modules

The function modules "Prozess_PPO…" are called up in the cyclic section of the program. In addition
to the process modules, the associated instance modules "Inst_PPO" are also required.
Example:
Purpose:
The function module "Prozess_PPO…" is used to control a frequency inverter with up to three setpoint
inputs (Setpoint SW / Actual value IW). According to the type, up to three 16 bit setpoint inputs or one 32 bit and a 16 bit setpoint input (for positioning tasks with a 32 position setpoint) can be controlled on the inverter. In this case, the resulting actual values correspond to a 32 bit value as Actual Value 1 (AV_1) and a 16 bit value as Actual Value 2 (AV_2).
In addition to supplying the module with the corresponding number of 32 bit setpoints (in real format), the module also processes control tasks (Control word STW / Status word ZSW) such as error acknowledgement and enable signals. The description of the inputs and outputs is summarised in Section 3.3.
Table 3: Assignment of function modules
The process modules
Prozess_PPO1_16 and Prozess_PPO3_16 Prozess_PPO2_16 and Prozess_PPO4_16 Prozess_PPO2_32 and Prozess_PPO4_32
are more or less identical. The difference between them is only the provision of an extended data range of 4 words for the parameter identification data PKW for the PPO types 1 and 2.

4. Parameter modules

The parameter modules are used to read out parameter values from the frequency inverters or to write values into them. All modules access the parameters in reading mode.
For acyclic reading and writing, access to the memory addresses (PKW channel) of the frequency inverter is not via the peripheral addresses but rather via the diagnostic address. This is explicitly specified in the dialogue during the hardware configuration. Access to the addresses is performed with standard Siemens function modules, which are available in the library of the Simatic Manager. Therefore access to the parameters no longer depends on the PPO type. With PROFIBUS, access to the parameters is only possible for Profibus slaves of type DPV1 and for PROFINET IO devices.

4.1.1 Purpose of parameter modules for cyclic data communication

The function modules "Para_PPO1+…" are called up in the cyclic section of the program. In addition
to the parameter modules, the associated instance modules "Inst_PPO1+..." are also required.
Example:
Purpose:
The function module "Para_PPO+..." is used to read a specific parameter via statement of the parameter number and index or to write this into the frequency inverter. In addition, parameters which provide a setting facility which depends on the parameter set can also be accessed. Please refer to the manual for the relevant frequency inverter for information regarding which parameters can be read or written with index and/or depending on the parameter set.

WARNING
The maximum number or write cycles on the EEPROM of the frequency inverters is limited to 100,000 cycles. Continuous writing to the EEPROM therefore results in the destruction of the EEPROM.
Writing to the RAM of the frequency inverter should therefore be used for writing parameter data. The setting for this is made in parameter P560 of the frequency inverter.

4.1.2 Purpose of parameter modules for acyclic data communication

The function modules "Para_acyc+…" are called up in the cyclic section of the program, however they
operation in the acyclic communication process. In this way, access to the data of a frequency inverter must not necessarily be concluded within a cycle of the PLC program, but rather can be continued in the following program cycle. In addition to the parameter modules, the associated instance modules "Inst_..." are also required.
Example:
Access on the frequency inverter is via the diagnostic address. This address was specified during the hardware configuration and must be individually specified for each bus participant. In the modules described here, the diagnostic address is always 4092 (see also Section 2.1.1).
Purpose:
The function module "Para_acyc+..." is used to read a specific parameter via statement of the parameter number and index or to write this into the frequency inverter. In addition, parameters which provide a setting facility which depends on the parameter set can also be accessed. Please refer to the manual for the relevant frequency inverter for information regarding which parameters can be read or written with index and/or depending on the parameter set.
Only Para_acyc_W16 and Para_acyc_W32: When writing the parameter, a distinction can be made as to whether the data are to be written into
the RAM or into the EEPROM of the frequency inverter. If the data are written into the EEPROM, the information is retained, even if there is a power failure,
whereas information which is written into the RAM is lost. However, the number or write cycles for an EEPROM is limited, so that this variant for writing date should be chosen with care.
