Lenze is launching a range of fully scalable i500 frequency inverters, saying the functions and power of the i500 frequency inverters can be tailored to virtually any machine application and industrial environment. Compliant with efficiency class IE2, Lenze i500 inverters feature a slim design and peak energy efficiency in the range 0.25-45 kW.
Darrow Hanesian, Director of Product Management at Lenze, states: "Lenze set out to bundle cutting-edge control technologies into a customisable IE2-compliant package for machine builders. All of the i500 components are stringently designed for optimal energy efficiency, which boosts the value for machine builders by increasing power density and allowing smaller cabinet dimensions."
The compact, modular Lenze i500 frequency inverters feature a lower housing depth along with a sophisticated cooling system to reduce heat losses and allow side-by-side installation. This means minimal wiring and a smaller control cabinet.
i500 drives come with two particular variants: the i510 suits simpler applications with a single- or three-phase supply and power ratings up to 2.2kW. Alongside is the dimensionally identical i550 covering the same power range but with a three-phase extension up to 45kW. The i550 also offers extended functionality such as DC bus connection, plug-in STO (safe torque off) option and dynamic braking. To achieve functional scalability, the i550 power section is structurally separate from the control unit that gives the option for different forms of field bus communication, including Ethernet, multiple I/O interfaces, and plug-in options for a keypad, a USB interface or a wireless LAN module. These interfaces provide users with greater flexibility and ease of commissioning, parameter setting, maintenance and diagnostics. The wireless LAN module can communicate with a PC or via a smartphone keypad app.
With the new Lenze i500 series of frequency inverters, the development team placed importance on easy use and universal application as well as these being compact, high-performing drives. This ambition is visible in the keyhole mountings, the spring terminals and the plug-in modular extensions to the drive. All these features make it easy to install and wire the new i500 frequency inverters into the control cabinet, thereby saving a great deal of time.
This promise of ease of use continues during commissioning when the inverter is being parameterised. This can be done with the help of either the Lenze 'Engineer' software tool with a PC, or a new Lenze smartphone app. Another option is WLAN, a plug-in module that is destined to be a real time-saver - especially when control cabinets are located in places with difficult access and connecting a cable between the inverter and a laptop proves to be difficult. Instead of having to go to the trouble of getting to where the drives are physically located, the WLAN module can be used to establish a mobile connection to the drive settings.
Hanesian concludes: "Experience shows that each customer's application is unique. Our new Lenze i500 frequency inverters are structured and built to give machine builders the ultimate in energy savings, integration and design flexibility to specify precisely the features they need."
