Altivar ATV 71 is a Schneider Electric high performance inverter drive suited to constant torque applications up to 630kW. By adding an ATV-IMC Integrated Controller Card type S with its PLC functionality the inverter integrates seamlessly into different hoisting applications. The ATV-IMC type S card accesses special libraries of hoisting Application Function Blocks developed […]
Anti-crab: Protect equipment and increase efficiency and crane service life. The ATV 71’s anti-crab function is an automatic realignment system that helps prevent crane skew and crab drift related to cranes with long spans. It maintains the path and the track parallel between the two bogies independent of load position or initial crane assembly. Operating Principle Anti-skew […]
This paper produced by Schneider Electric USA explores the affect of various short-circuit current ratings (SCCR) values to Altivar ATV 61 and ATV 71 inverter drives. It considers potential equipment damage at low (5kA) and high (100kA) short-circuit currents and compares the impact of adding a 3% line reactor and Adding a DC Choke […]
Maximum performance: flexible and reliable The Schneider Electric Altivar 71 is a high performance AC variable speed drive for constant torque applications using synchronous three-phase motors from 0.37 to 630kW. The Altivar 71 offers ease of use by simplifying complex applications with its customisable capability. This mean it saves time and […]
Using Altivar ATV 61 inverter drives for saving energy on fan and pump motors offers some of the fastest returns in terms of payback time. In most cases fans and pumps do not need to run at full speed. They can be controlled manually or electronically to run at the right speed required by the […]
