tailieunhanh - Variable speed drives Altivar 71

The Altivar 71 range of variable speed drives is able to respond to the most exacting requirements thanks to its different types of motor control and numerous onboard functions. It is suitable for the most demanding drives: b Torque and speed accuracy at very low speeds, high dynamics with Flux Vector Control (with or without sensor) b Extended frequency range for high-speed motors b Connection of special motors and drives in parallel thanks to the voltage/frequency ratio b Static speed accuracy and energy savings for synchronous motors in open loop mode b Smooth flexibility for unbalanced machines with the ENA System (Energy Adaptation System) The functionality of the Altivar 71 drive boosts. | Variable speed drives Altivar 71 Catalogue March 05 For 3-phase asynchronous motors from to 500 kW a brand of Schneider Electric Contents Variable speed drives for asynchronous motors Altivar 71 Selection 2 2 Variable speed drives 8 14 18 Options 20 26 encoder interface 29 I O extension 31 Controller Inside programmable 39 communication buses and 46 resistance braking units .page 49 braking 51 hoist 53 network braking 63 Reduction of current harmonics DC 69 line 72 passive 74 additional EMC input 78 Output filters motor 82 sinus 85 Combinations of variable speed drives and 86 90 112 Motor 128 Mounting 132 Combinations of functions and 140 142 Compatibilty table for 174 PowerSuite software 179 Ethernet TCP IP 184 Communication via Fipio 188 Communication via Modbus 191 Communication via Modbus Plus 196 Communication via Uni-Telway 199 Communication gateways LUF 201 Communication gateway LA9 203 Schneider Electric 204 Product reference 210 Tel em ecan ique
