Motor mounted drive range is extended to 7.5kW

23 February 2012

The Lenze 8400 motec range of terminal box inverters has been extended and new covers powers from 0.37 to 7.5kW. By decentralising frequency inverters instead of fitting them in the control panel, machine cabling and installation is simplified. The motec range can be mounted directly on the motor in place of the terminal box, or onto a nearby surface - an option made easy with the enclosure rating of IP65. Either way, panel sizes can be reduced and the cost of cabling is lower.

Lenze offers the motec range as ‘drive packages’ consisting of the frequency inverter, the motor, and as appropriate an in-line or right angle gearbox. Two, four and six pole motors can be chosen together with options such as brakes, blowers and encoders. Power connection to the motec frequency inverter can be done with unshielded cables which reduce cost. Also the cable length can be minimised by looping the cable from one inverter to the next. The control connection can be from a simple AS-i bus, the more common industrial fieldbuses of Profibus and CANopen, or even by Profinet and EtherCAT real time buses. Choosing the control bus is simply a matter of plugging in the appropriate communication module.

Performance of the 8400 motec inverters is dynamic but controllable with PID integrated and options for sensorless or encoder feedback operation. The speed setting range is an excellent 1:24 when used with Lenze motors. Safe Torque Off to PL e of ISO 13849-1 is integrated as standard. Also standard as an option that can be chosen from the free set-up software is the VFC eco energy saving feature. This reduces the magnetisation current in the motor under partial load operation, and savings in energy usage of up to 30% are possible.

The decentralised design of the 8400 motec inverters suits large machines where the reductions in shielded cabling are significant. They also suits machinery where panel space is not available. The range extension up to 7.5kW suiting the majority of production machinery makes it easy to install, saving time and cabling costs. As part of the Lenze L-force portfolio, they are built into the L-force Engineer software meaning that programming, commissioning and diagnosis are easy too.
