The functionality of the Lenze 9400 servo range has been extended with uprated power capacity and curve generation software. For applications with power requirements above 75kW that require a low overload capacity, the continuous power ratings of the 9400 drives have been increased by up to 40%. This allows both cost and space savings. In addition the ability to generate curved motion paths, as would be done by a mechanical cam, is increased and now 256 cam profiles can be stored in the drive.
Certain types of machinery require servo performance in terms of fast response and precise speed holding, but do not need high peaks of torque. An example is extruder machinery. For powers above 75kW and up to a maximum of 420kW, the 9400 servo drives have uprated continuous capacity with reduced peak torques. This increase is available on standard drives at no extra cost. As well as lower purchase cost, customers gain with smaller panel sizes and typically 1kW of reduced power losses.
Servo drives in machinery such as packaging or pick and place can replace mechanical cams. The same complex curved motion paths can be achieved without wear and at high speeds. The Lenze 9400 servo drives across the full range starting at 0.37kW have new cam software that permits a number of different profiles to be stored for different machine settings. Up to 256 cam profiles can be stored with up to 50 interpolation positions per cam. Alternatively fewer profiles are possible with interpolation up to 16384 points for complex and highly accurate paths. Lenze L-force Engineer software makes data import and automatic path generation easy.
The 9400 servo range is part of the Lenze L-force product portfolio. Drives are available for single or multi-axis configuration with two positions for optional plug-in communications that can include real-time fieldbuses such as ProfiNET and PowerLink. A further plug-in position allows drive safety functionality such as Safe Torque Off and Safe Stop.
