Siemens Introduces Sinamics V20 AC Drive

Siemens releases a new single-axis Sinamics V20 AC drive, frame size E, with low overload (LO) and high overload (HO) ratings. With a power rating ranging from 1/6–40hp at 480V AC, Sinamics V20 drives are available in five frame sizes and are suited for material handling, conveyor, pump, fan and compressor applications. The compact drive can be connected and installed using the conventional wall-mounting method or, optionally, mounted with heat sinks pushed through the enclosure wall.

The integrated basic operator panel (BOP) enables commissioning and operation on-site.  The universal serial interfaces allows for easy connection to Simatic programmable logic controllers (PLCs) and a Modbus interface is included for communication with third-party controls.  Pre-built connection and application macros facilitate application-specific settings.  For units with power ratings higher than 10hp, a braking resistor can be connected directly to the integrated braking chopper.

Parameters optimized for one application can be transferred to other drive units using SD cards via the basic operator panel or the battery-operated parameter loader.  The built-in display lists only those parameters changed from the factory default values. Tailored inter-connectivity and application macros provide correct settings.  The Keep Running Mode automatically adapts the V20 drive to the power supply to achieve higher availability when operated on unstable networks.  Line fluctuations are compensated for internally and error messages are acknowledged autonomously.  Enhanced cooling and coated PCBs and electronic components make the Sinamics V20 rugged and reliable even in harsh environments, according to the company.

The Sinamics V20 is equipped with an energy-optimized control mode (ECO-mode) for increased energy efficiency.  ECO-mode automatically adapts the magnetic flux in the motor to the optimum operating point.  The DC link coupling enables efficient energy utilization of drives grouped together.  The Sinamics V20 can be set to hibernation mode, which prolongs the service life of the motor and reduces system component wear. The drive displays real-time energy consumption on the operator panel display.
