Variable speed AC drives

The Telemecanique Altivar 71 variable-speed ac drive sports dual microprocessors running motor-control algorithms.

Advanced materials reduce drive size by 15% compared to previous generations. The new drive family features a common user interface and options from 0.5 to 700 hp. A quickstart menu incorporates macro-configurations for easy commissioning. Integrated Modbus and CANopen protocols permit integration into devicelevel networks. Monitoring and diagnostics can take place through an Ethernet or Bluetooth wireless connection. Among the many new features is an integrated oscilloscope function to detect operational drift on machines. Other features include advanced thermal protection, an integrated power-removable safety function, drive protection, and environmental protection in accordance with the WEEE regulations and RoHS standards. The power-removal function has been certified by an independent body for e-stop requirements.
