NORD LogiDrive standardised drive systems

NORD DRIVESYSTEMS has established three preferred sizes for efficient variable-frequency drives in materials handling and conveyor applications. The standardised drive systems simplify purchasing, engineering, commissioning and spare parts stocking, as well as being easy to install, operate and maintain. Limiting the number of variants can yield greater total cost of ownership (TCO) savings than any other measure except for lowering energy consumption, according to the company.

The LogiDrive line of three preferred drive variants is optimised for intralogistics applications and can be used for conveyor systems spanning many hundred metres. The VFDs allow for simple daisy-chaining as short power lines can be connected from one drive to the next. Three geared motor variants meet all typical performance requirements: IE4 permanent-magnet synchronous motors with power ratings of 1.1, 1.5 or 2.2 kW are combined with efficient two-stage helical-bevel gearboxes in two sizes for torques up to 260 Nm. Robust frequency inverters from the NORDAC LINK series enable a wide range of speeds. The systems feature a high overload capacity and offer a versatile range of functions. Interfaces for all commercially available communication protocols are available, including Profinet, Ethernet POWERLINK, EtherCAT and EtherNet/IP.

The systems are easy, quick and safe to install due to coded plug-in connectors. Maintenance switches, key switches and direction switches on the devices allow for flexible direct access to individual drive axes for set-up or service. Sensors and actuators can be connected via M12 plugs. Plug-and-play, pre-parameterised inverters simplify maintenance, and drive components can be individually replaced.
