Logistic systems found in modern warehouses utilise belt and roller conveyors with modules for curves, lifts, spurs and turns. Lenze decentralised drive technology puts the inverter drive together with the geared motor.
Aside from saving on panel space, installation costs are significantly reduced by the ability to connect the motor power from an energy bus of standard cabling. Conventional solutions with the drive in the panel would require individual wiring of shielded cables to each motor.
The Lenze 8200 motec frequency inverters are enclosed to IP65 and can be mounted either on the motor or to any flat surface nearby. They allow process optimisation - acceleration and deceleration ramps can be set by a hand-held keypad or a PC.
A CAN system bus is integrated which gives the option of control from a central location. To fit with any existing factory standard, plug-in communication modules can be added, for example PROFIBUS and AS-i.
The motec inverters are available as free-standing drives in a power range 0.25 to 7.5kW, alternatively as part of a geared motor from the Lenze G_motion range. Gearboxes can be in-line helical or planetary, also right-angle helical worm, bevel and helical bevel models.
When mounted on the motor or within 2m of the motor, no shielded cabling is required and EMC limits to Class A and B are met. These drives are proven on continuous running conveyor applications, but also for highly dynamic intermittent operation such as with parcel diverters.
In all cases fast installation with reduced cabling requirements together with smaller panels brings big economic benefits.
