P033 [Motor OL Current] on a PowerFlex 525 holds exactly one number. Land two 3 HP motors on T1, T2 and T3 and that number is now watching the pair as though they were one 6 HP machine, which leaves neither motor protected. That single parameter is the whole argument. Two standard induction motors will … Read more
F013 is current leaving the motor circuit for earth. A megger routine that separates motor, cable and junction box, with the readings that decide it.
Choose DOL or a drive, wire the stop so it works without the PLC, set the drive parameters and tags, then read the fault codes when it trips.
Zone accumulation, cascade start and stop, jam timers that do not nuisance trip, and driving a PowerFlex 525 over EtherNet/IP from a CompactLogix.
Set up EtherNet/IP between a Logix controller, remote I/O and a drive: RPI, unicast vs multicast, MSG paths, and the fault codes you will really see.
Allen Bradley Power Flex AC Driver Allen Bradley Power Flex AC drives can communicate with the desired communication protocol by installing Ethernet/IP, ControlNet, and DeviceNet modules. In the main chassis, we will continue with the article where Control Logix PLC is located and we added an ethernet module in our previous article. New Module Add … Read more
