No matter what area of plant control you choose to scrutinise, there are few optional equipment alternatives that offer the operational benefits and cost savings of frequency inverters.
The new vector inverters deliver 180% overload torque for up to 60 seconds, useful for starting large inertias.
Speed control without the need for encoder feedback is excellent, with full torque available down to 1Hz.
Great communication flexibility has been achieved with the unique design of a third plug-in position on the face of the inverter.
Customers can choose what they need from a range of plug-in modules and avoid paying for unwanted features.
The upper communication position is usually for a programming keypad but bus modules can be fitted.
The middle position accepts a wide range of fieldbus modules, for example the popular PROFIBUS and DeviceNet and new options of LON and AS-i.
The lower position is for additional I/O modules.
The new vector inverters act as a bus gateway.
Firstly they can enable a bus-to-bus conversion, for example accepting commands from a higher level controller in PROFIBUS and passing them on to a network of drives in lower cost CANbus.
Also, digital input signals taken into the inverter can be transferred to the bus without influence on the inverter performance.
The Lenze 8200 vector inverters are part of an integrated range starting at 0.25kW.
Existing drive software can be used and retrofits are easy with the same dimensions as before.
The Lenze range includes 1-phase versions up to 2.2kW and terminal box/IP65 models up to 7.5kW. Request a free brochure from Lenze ...
