The i650 motec is particularly impressive thanks to its integrated Logic PLC and a positioning function that enables independent motion control without a higher-level controller. This makes the system ideal for applications such as format adjustments or film wrappers.

300 percent overload torque

High performance is also important to users: "We promise 300% overload torque from standstill and we deliver. Starting from standstill to full load is possible without any problems and without motor feedback," emphasizes Klaus Dierkes, Product Manager Electromechanics. This means that the system can be designed more precisely for continuous operation, as it is not oversized, and then delivers the required power immediately.

Outputs from 0.25 to 22 kilowatts for dynamic applications

Lenze offers the new m550 synchronous motor with outputs from 0.25 to 11 kilowatts and the m650 for dynamic applications with outputs from 0.75 to 22 kilowatts. Both can be seamlessly combined with the gearboxes from the Lenze modular system. There is also a choice of helical, angular or bevel gearboxes for a wide range of requirements.

New EASY System Designer as a web-based engineering assistant

The first test customers have worked with the new EASY System Designer from Lenze during the design phase. The result: a precisely dimensioned drive solution through to energy-efficient machine design. The web-based engineering assistant shows the energy consumption of the respective application and drive components.

Sensorless and safe

Thanks to precise control of the m550/m650 synchronous motor, encoderless positioning is possible with the i650 motec. The integrated safety functions such as Safe Torque Off (STO) or Safe

Energy efficiency and transparency included

The Motor Drive System is also designed to impress in terms of sustainability: the combination of motor, gearbox and inverter reduces motor losses by up to 60 percent. The integrated energy recovery in the motec automatically feeds excess energy back into the grid - without any additional hardware. Machine operators also receive high-quality information from the machine sensors via the IO-Link interface and benefit from increased system transparency.

Budget-friendly chain reaction

According to the supplier, the new Motor Drive System is also extremely resource-friendly. The sensorless feedback means a budget-friendly chain reaction on the hardware side: no expensive feedback system, more compact drive, no expensive cables. Another effect: assembly and installation are quick and safe. If the highly efficient motor is controlled with the decentralized i550 or i650 motec inverter, there is no need for even more hardware, as braking resistors are not required. The regenerative unit integrated in the motec feeds any braking energy back into the grid. The i500 cabinet inverters can also exchange excess energy via the DC network and make it available to other axes.

Performance of a closed control loop without motor feedback system and cabling

Lenze also has a new solution for the format adjustment of printing rollers, which is frequently used in printing presses: "We use the SLSM algorithm (Sensorless Synchronous Motor Control) in the inverter, which enables us to achieve the performance of a closed control loop without a motor feedback system and cabling. This allows us to achieve sensorless and precise positioning," says Klaus Dierkes.
