Siemens frequnecy inverters Micromaster 430 general purpose series

Siemens frequency inverter Micromaster 430 series description.

Application.
The MICROMASTER 430 inverter is suitable for a variety of variable-speed drive applications. Its flexibility provides for a wide spectrum of applications. It is especially suitable for use with industrial pumps and fans. The inverter is especially characterized by its customer-oriented performance and ease-of-use. It has more inputs and outputs than the MICROMASTER 420, an optimized operator panel with manual/automatic switchover and adapted software functionality.

Variant dependent options.

EMC filter, Class A.
All 7.5 kW to 90 kW inverters are supplied with an internal filter Class A. For inverters 110 kW to 250 kW, EMC filters Class A are available. In this performance range, the EMC filters are only permitted to be used in combination with a line commutating choke. The requirements are fulfilled using shielded cables with a max. length of 25 m.
EMC filter, Class B.
Available for inverters 7.5 kW to 15 kW with an internal Class A EMC filter. The requirements are fulfilled using shielded cables with a max. length of 25 m. For inverters 18.5 kW to 90 kW without filters, EMC filters of Class B from Schaffner can be used.The requirements are fulfilled using shielded cables with a max. length of 25 m to 50 m (depending on the type, details on request). With this filter, the inverter complies with the emission standard EN 55 011, Class B for conducted interference emissions.
Leakage currents: The leakage currents of the inverters with/without filter (internal/external) may exceed 30 mA. Typical values in practice are between 10 mA and 50 mA. The exact values depend on the design, environment and cable lengths. Interference-free operation with residual current operated devices with a trigger value of 30 mA cannot be guaranteed. However, operation with residual current operated devices with a trigger value of 300 mA is possible. 
LC filter and sinusoidal filter.
The LC filter/sinusoidal filter limits the rate of rise of voltage and the capacitive charge/ discharge currents which usually occur with inverter operation. This means that much longer shielded motor cables are possible when using LC filters/sinusoidal filters and the service life of the motor achieves values similar to those with direct mains operation. Use of an output choke isn’t required with that. Please note when using LC filters/sinusoidal filters: 
- Only V/f, FCC control permissible 
- Please observe the derating of 15% when selecting the appropriate inverter 
- Operation only permissible with 4 kHz pulse frequency Note: Please observe derating for frame sizes FX and GX. 
- The output frequency is limited to 150 Hz 
- Operation and commissioning only with connected motor as the LC filter/sinusoidal filter is not idling-proof!
The LC filters/sinusoidal filters can be used for all MICROMASTER 430 inverters of frame sizes C to GX. 
- Frame sizes D to F: The LC filters, frame sizes D to F, are designed for mounting upright in the control cabinet. Due to leakage flux lines caused by physical sources, a minimum distance of 50 mm to adjacent modules and metal parts is recommended. 
- Frame sizes FX and GX: The sinusoidal filters, frame sizes FX and GX, are designed for mounting upright in the control cabinet. Due to leakage flux lines caused by physical sources, a minimum distance of 100 mm to adjacent modules and metal parts is recommended.
Line commutating choke.
Line commutating chokes are used to smooth voltage peaks or to bridge commutating dips. In addition, line commutating chokes reduce the effects of harmonics on the inverter and the power supply. If the line impedance is < 1 %, a line commutating choke must be used in order to reduce the current peaks. No limits are currently defined in the EN 61 000-3-2 standard for professionally used devices with a connected load > 1 kW. This means that the inverters with an output power
0.75 kW comply with the EN 61 000-3-2 standard. However, in accordance with the regulations of EN 61000-3- 12 “Limits for harmonic currents > 16 A and
75 A per phase” an approval is necessary from the power supplier for drives that are intended to be connected to the public low-voltage network. Please refer to the Operating Instructions for the values of the harmonic currents.
Output choke.
Output chokes can be supplied for reducing the capacitive compensation currents and dV/dt in the case of motor cables >50 m (shielded) or > 100 m (unshielded).
Gland plate.
Gland plates are available for inverters of frame size C. All the other frame sizes have the shield connection for the control cable integrated in the inverter. The shield for the power cable has to be connected externally (e.g. in the control cabinet). Exception: Inverters of frame sizes D and E and frame size F with integrated class A filter. In this case the shield connection is integrated in the inverter. The gland plate facilitates the shield connection of power and control cables and thus ensures optimum EMC performance.

Siemens vfd Micromaster 430 series general installation instructions.

- A maximum of two footprint components plus inverter are permissible. 
- If an LC filter is used, it must be mounted directly on the wall of the control cabinet due to weight reasons. If an LC filter of frame size C is used, therefore, only one footprint component is permissible. If a line choke and LC filter are used, the line choke must be located on the left of the inverter. Required distance between line choke and inverter: 75 mm. 
- The EMC filter must be mounted directly below the frequency inverter if possible. 
- If mounted on the side, the line-side components are to be mounted to the left of the frequency inverter whereas the output-side components are to be mounted to the right of the frequency inverter.

Basic Operator Panel 2 (BOP-2).
With the BOP-2, individual parameter settings can be made. Values and units are shown on a 5-digit display. A BOP-2 can be used for several inverters. It can be directly mounted on the inverter or in a control cabinet door using a mounting kit.

PROFIBUS module.
For a complete PROFIBUS connection with up to
12 Mbaud. Remote control of the inverter is possible with the PROFIBUS module. Remote control and operation at the inverter can be combined using an operator panel plugged onto the PROFIBUS module. The PROFIBUS module can be supplied by an external 24 V DC power supply and is thus also active when the inverter is disconnected from the power supply. Connection by means of a 9-pin Sub-D connector (available as an option).
DeviceNet module.
For networking the inverters to the DeviceNet fieldbus system widely used on the American market. A maximum transmission rate of 500 kbaud is possible. Remote control of the inverter is possible with the DeviceNet module. Remote control and operation at the inverter can be combined using an operator panel plugged onto the DeviceNet module. The connection to the DeviceNet bus system is made using a 5-pin connector with terminal strip.
CANopen module.
Using the CANopen communications module, an inverter can be linked to the CANopen fieldbus system and remote control is then possible. Remote control and operation at the inverter can be combined using an operator panel plugged onto the CANopen module. The module is connected to the bus system through a 9-pin Sub-D connector.
Connection kit for PC to inverter.
For controlling an inverter directly from a PC if the appropriate software has been installed (e.g. STARTER). Isolated RS-232 adapter module for reliable point-to-point connection to a PC. Includes a Sub-D connector and an RS-232 standard cable (3 m).
Start-up tools. 
- STARTER is a graphic start-up software for guided start-up for MICROMASTER 410/420/ 430/440 frequency inverters under Windows 2000/ XP Professional. Parameter lists can be read out, altered, stored, entered and printed. 
- DriveMonitor is a start-up software for listoriented programming of frequency inverters. This program executes under Windows 98/NT/2000/ME/ XP Professional.
Both programs are included on the Docu DVD which is provided with every inverter.
