Siemens V20 VFD
Siemens SINAMICS V20 is a variable frequency drive (VFD) designed for basic applications in various industries, including plant and machinery construction, automation, and drive solutions. The VFD comes in seven different frame sizes and covers a power range from 0.12 kW up to 30 kW (1/6 hp up to 40 hp).
The SINAMICS V20 is cost-effective, reliable, and easy-to-use, with quick commissioning times, ease of operation, and robustness. The VFD is equipped with a control technique to achieve optimal energy efficiency through automatic flux reduction and displays the actual energy consumption, making it an energy-saving solution.
The VFD is easy to install and can be mounted on the wall or pushed through. It also has an integrated braking chopper for 7.5 kW to 30 kW (10 hp up to 40 hp), electromagnetic compatibility (EMC) category C1/C2, and can be operated without a power supply. The SINAMICS V20 Smart Access web server module allows easy commissioning with mobile devices or laptops.
The VFD is suitable for various applications, including pumping, ventilating, and compressing, such as centrifugal pumps, radial/axial fans, compressors, belt conveyors, roller conveyors, and chain conveyors. The VFD offers advantages such as high availability, broken belt detection, pump protection against cavitation, and precise stopping with quick stop.
In addition, the SINAMICS V20 has a compact design, making it suitable for small cabinets. It also has a parameter loader that allows easy parameter settings transfer, requires less technical support, has a short commissioning time, and is delivered to the customer already preset.
The VFD also supports communication via USS and Modbus RTU at terminals, making it easy to access selected process/control data. With up to three communication modules CM1241 added to the SIMATIC S7-1200 and one communication board CB1241, a USS or Modbus communication can be established to SINAMICS V20 drives.
- The VFD supports various control modes, including V/f, V²/f, and vector control with encoder feedback.
- The VFD has integrated I/O, including three digital inputs, one analog input, and one relay output.
- Communication options include USS and Modbus RTU, and the VFD can be connected to up to 64 drives using USS or up to 32 drives using Modbus RTU.
- The VFD has integrated energy-saving functions, such as an ECO mode for V/f and V²/f control and a hibernation mode that stops the motor when demand is low.
- The VFD has a wide voltage range, advanced cooling design, and coated PCBs to increase robustness and reliability.
- The VFD supports motor staging, which extends the flow range by adding two more fixed-speed drives in cascade.
- The VFD has a built-in BOP (Basic Operator Panel) for basic operator actions and can be easily commissioned using a mobile device or laptop with the web server module SINAMICS V20 Smart Access.
- The VFD has various protective features, such as pump protection against cavitation, broken belt detection by monitoring the load torque, and frost and condensation protection for motors in extreme environmental conditions.
- The VFD also supports Keep Running mode for uninterrupted operation and exchange of regenerative energy via the DC link.
- The drive offers a variety of control modes, including V/f, V²/f, and sensorless vector control.
- It features a wide voltage range, with single-phase input voltage options of 200-240V and three-phase input voltage options of 380-480V.
- The VFD has integrated application and connection macros that simplify commissioning and configuration.
- It offers a range of built-in protections and monitoring functions, including high and low overload modes for motor protection, broken belt detection, and monitoring of energy and water flows.
- The V20 drive is designed for easy installation and use, with features like push-through and wall mounting and the ability to operate out-of-the-box without additional options.
- The drive is compatible with a range of communication protocols, including USS and Modbus RTU, and can be easily integrated with Siemens S7-1200 controllers.
- Siemens offers a range of accessories and options for the SINAMICS V20, including a Smart Access module for mobile commissioning, various operator panels, and different braking options.
