Sensorless vector inverters
2nd Quarter 2010
Electrical switching & drive systems & components
In March 2010 Bonfiglioli launched its AgilE series of sensorless vector inverters. The range covers power requirements from 0,25 to 11 kW, single and three-phase, 230 and 400 V. The inverters sport many of the features commonly associated with modern drive technology, including open loop vector control of brushless motors, multimediacard (MMC) memory cards and network management for sensorless drive applications.
“These new inverters have an intuitive menu structure, clearly marked terminals and easy programming of the built-in PLC functions,” said a company spokesperson. “Start-up and running costs are minimised by the provision of ready-to-use pre-programmed function that guide even inexpert programmers towards the ideal configuration. A standby mode lets one disable functions that are not needed when the unit is not driving the motor, resulting in important energy savings under active but idle conditions.
AgilE inverters are equipped with various integrated system buses based on CANopen and Modbus protocols and also boast an impressive nine digital and two analog inputs and one analog and four digital (including a relay) outputs. Even the basic model features an input for 24 V back up power and an EMI filter, as well as a 'Safe torque off' function.
The mechanical solutions for installation in control panels are also intelligent:
* The range includes versions for feed-through mounting and DIN rail adapter.
* A Cold Plate version means that these inverters can be used with all types of cooling surface.
Special attention has been paid to product lifecycle issues. The result is a drive capable of guaranteeing a significantly longer than average working life.
* Parts subject to wear, like the fan and capacitors, can be replaced quickly and easily to extend the drive’s useful life in tough and demanding applications.
* A special version with dielectric capacitors that last longer than conventional capacitors.
* The smallest sizes of AgilE inverters do not require a fan, promising maintenance-free operation for the entire lifetime of the unit.
* Advanced diagnostic, prediction and troubleshooting functions.
