AC/DC Drive Control
Description:
The Altivar 71 is a new frequency inverter for three-phase squirrel cage asynchronous motors that incorporates the latest technological developments and functions suitable for the most common applications, including horizontal and vertical materials handling, packing/packaging, special machines, ventilation/air conditioning, pumps and compressors. Its numerous integrated options enable it to be adapted to sophisticated and advanced control systems. For applications in which only a small amount of overtorque is required, drives with power ratings from 0.37 kw to 500 kw.
Connectivity:
Modbus
Features:
The main functions are starting, dynamic braking and braking to a standstill, and speed control; energy saving, PI regulator (flow rate, pressure, etc.); brake sequence; speed loop with tachogenerator or pulse generator; +/- speed, S ramps, U ramps, preset speeds, JOG operation; automatic catching a spinning load with speed detection (catch on the fly); adaptation of current limiting according to speed for ventilation applications; automatic limitation of low speed operating time, motor and drive protection.
