Siemens frequency inverters Micromaster 420 general purpose series

Siemens frequency inverter Micromaster 420 series description.

Application.
The MICROMASTER 420 inverter is suitable for a variety of variable-speed drive applications. It is especially suitable for applications with pumps, fans and in conveyor systems. It is the ideal cost-optimized frequency inverter solution. The inverter is especially characterized by its customer-oriented performance and easeof-use. Its large mains voltage range enables it to be used all over the world.

Siemens vfd Micromaster 420 series design.

- 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.

Siemens frequency inverter Micromaster 420 series variant independent options.

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

Advanced Operator Panel (AOP).
The AOP enables parameter kits to be read out of the inverter or to be written into the inverter (upload/download). Different parameter kits can be stored in the AOP. It has a plain text display with the possibility of switching between several languages.

Up to 30 inverters can be controlled from an AOP via USS. It can be directly mounted on the inverter or in a control cabinet door using a mounting kit.
Asian Advanced Operator Panel (AAOP).
The AAOP is the Chinese version of the AOP operator panel. It has an enhanced display and supports the operating languages of Chinese (simplified) and English.

Cyrillic Advanced Operator Panel (CAOP).
The CAOP is the Cyrillic version of the AOP Advanced Operator Panel. It supports the Cyrillic, German and English operator languages.
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.
