Frequency Inverter
VARIO control & TravelMaster

TravelMaster and VARIO control  frequency inverter offers steplessly adjustable speeds of long and cross drives and therefore low-sway, precise and gentle working.

Soft starting and stopping lowers wear on gearbox, wheels and rails and reduces maintenance costs and material consumption. TravelMaster and VARIO control – a quick and simple profitability increase.

Thanks to the CANbus network, VARIO control  is already equipped for the future.

The VARIO control  frequency inverter is configured conveniently by use of a Bluetooth dongle connecting to a smartphone app.

Going forward, the advantages of the CANbus network will make additional hardware or tools completely unnecessary.
