Siemens frequency inverters SINAMICS V20 compact series VFD

Siemens frequency inverter SINAMICS V20 series - the perfect drive solution for basic applications.

SINAMICS V20, the simple and versatile drive system for basic demands.
Today, in an increasing number of applications, automation and drive solutions are required to automate motion sequences. The SINAMICS V20 from Siemens offers a simple drive solution for these types of applications. It sets itself apart with its quick commissioning times, robustness, ease-of-operation and cost-efficiency. With five frame sizes, it covers a power range extending from 0.12 kW up to 30 kW (1/6 hp up to 40 hp).
Minimize your costs.
In today’s competitive environment, engineering, commissioning and operating costs must be kept to a minimum. With SINAMICS V20, you have the precise answer. To increase energy efficiency, the drive uses a control technique, which automatically reduces motor flux when the motor is not operating at optimal loading (ECO mode). The V20 displays actual energy consumption and has a “hibernate” mode for periods when the drive is not being used — allowing energy consumption to be drastically reduced.

Siemens vfd SINAMICS V20 series communication.

The communication port is available at the terminals. The preset parameters of the USS and Modbus RTU are defined in the connection macro.
- Easy integration into existing systems 
- Easy integration into micro automation systems 
- Easier commissioning through standard libraries and connection macros

Braking module in Siemens frequency inverter SINAMICS V20 series.

The dynamic energy is dissipated as heat in a braking resistor with an adjustable duty cycle of between 5–100%.
- Possible to use dynamic braking to increase braking performance 
- Drives ≥ 7.5 kW have an integrated braking module. In this case, the braking resistor can be directly connected.

Siemens drive SINAMICS V20 parameter cloning.

Parameter settings can be easily transferred from one unit to another using the parameter loader — even without a power supply.
- Less technical support required
- Short commissioning time 
- The product is delivered to the customer already preset.

Siemens vfd SINAMICS V20 series macro approach.

Connection and application macros to simplify I/O configuration and make the appropriate settings.
- Shorter training and commissioning time 
- Integrated and optimized application setting 
- Simple connection and application macros can be selected instead of configuring long complicated parameter lists 
- Errors caused by wrong parameter settings can be avoided.

Siemens frequency inverter SINAMICS V20 series Keep Running mode.

The function provides higher productivity in production by automatic adaptation in the case of unstable line supplies.
- Stable operation under difficult line supply conditions 
- Higher productivity through prevention of interruptions of the production line 
- Adaptation to application-relevant reactions through flexible definition in case of fault / alarm.

Robustness.

Better cooling design and coated PCB increase robustness of the drive in difficult application environments.

Energy reduction during operation.
Integrated ECO mode for V/f and V2/f automatically adapts the flux to save energy. The energy consumption can be shown in kWh, CO2 or even in the local currency.
- Energy saving during low dynamic load cycles 
- If the setpoint changes, the ECO mode is automatically deactivated 
- Tells end-users the actual energy that has been saved
Energy reduction during operation — DC coupling.
Applications that use SINAMICS V20 drives with the same power rating can share a common DC bus to reuse the regenerative energy.
- Generate and save energy in applications that use coupled motors 
- Pairs of identical drives can optimally share resources 
- Reduce the need for dynamic braking and external components

Inverter and motor only operate when the plant or machine re-quires them to. Hibernation mode will be automatically activated when the frequency demand or the feedback from a sensor drops below a specific threshold.
- Smart hibernation saves energy 
- Extended lifetime of motor 
- Reduced pump wear at low speed 
- Less time to program PLC code for pump / fan applications (PLC)
Cost-savings at low overload application.
SINAMICS V20 FSE (22 kW and 30 kW) integrated two different load cycles.
- Low Overload (LO): 110% IL ²) for 60 s (cycle time: 300 s) 
- High Overload (HO): 150% IH ³) for 60 s (cycle time: 300 s)
With low overload cycle, the drive can reach a higher output current and power. A smaller drive can be used. 
Optimally designed for a variety of applications:
- Low Overload for applications with a low dynamic response (continuous duty) 
- High Overload for applications with a high dynamic response (cyclic duty)
