Drives for food and beverage industry conveyors

The decentralised NORDAC ON frequency inverters from Nord Drivesystems have been specially designed for the requirements of horizontal conveyor technology. The NORDAC ON PURE in wash-down design features the nsd tupH surface treatment and is the right choice for applications in the food and beverage industry, especially when it comes to high hygiene requirements.

The NORDAC ON frequency inverter is characterised by an integrated multi-protocol Ethernet interface, IIoT capability, full pluggability and a compact design. Being part of the NORD modular system, they can be ideally combined with the manufacturer’s gear motor portfolio. The series comprises three variants: NORDAC ON for the operation with IE3 asynchronous motors, NORDAC ON+ for the combination with the highly efficient IE5+ synchronous motor, and NORDAC ON PURE in wash-down design.

The NORDAC ON PURE SK 35xP has been specially designed for conveyor applications in the food and beverage industry requiring powers up to 1.5 kW. The wash-down design with round and smooth surfaces allows for quick and easy cleaning – thanks to protection class IP69, this is also valid for demanding requirements. The nsd tupH surface treatment offers efficient corrosion protection.

To further reduce the cleaning effort, the required connections have been reduced to a minimum number of high-perfomance plugs for the connection of hybrid cables via a one-cable solution. The inverters are suitable for direct motor mounting or for wall mounting. Several inverters can be easily connected via daisy chain.

All frequency inverters in the series – NORDAC ON, NORDAC ON+ and NORDAC ON PURE – have a temperature range of -30 °C to +40 °C and are therefore also suitable for deep-freeze applications.

Since the NORDAC ON drives feature a wide speed and adjustment range, they allow for the reduction of variants, for example in large intralogistics systems. It is therefore possible to cover the required torques and speeds in a system using as few different drive variants as is economically feasible, and to optimise the total cost of ownership.

The NORDAC ON series’ high overload capacity is also advantageous for a variant reduction. All frequency inverters have an overload capability of up to 150 percent for 60 seconds, and by 200 percent for 5 seconds.
