Smart drive resolves blockages on its own

01 November 2016

Intelligent drives from Nord Drivesystems, with an integrated PLC, are said to be fully equipped to execute control sequences in a wide variety of applications. 

Featuring sensor interfaces and diagnostics as well as process control functions, the range is able to detect blockages and, in many cases, is able to independently restore normal operation which can help improve system availability and reduce servicing requirements.
If the drive is able to remove an obstacle, such as a blockage in a pipe, by repeatedly changing the motor speed and direction, it can then resume normal operation. If the problem persists, the inverter is able to submit an error signal to the control level and possibly initiate a fallback procedure, for example, by having other networked drive units unlock a bypass. Any such measures can be programmed individually specific to an application. This gives users independently operating, intelligent plant segments and machinery such as sorters, portioning and packaging systems, single pumps or groups of pumps, crushers, or screw conveyors. At the same time, optimum integration into automation networks is ensured. 

The inverter PLC is able to pre-process drive and application data for a higher-level controller for various uses including diagnostics.
