The takeaway conveyor’s 25B-D010N104, a 480 V PowerFlex 525 on a 4 kW motor, ran all day and tripped F005 OverVoltage on the first stop of every shift, with the PowerFlex 525 decel time at 2.00 s, b005 [DC Bus Voltage] sitting at 812 V in the fault history, and a belt carrying forty cartons … Read more
A CU240E-2 PN sits on the PROFINET IO system of a CPU 1516-3 PN/DP with G120 telegram 1 in its device view, the PLC is writing 16#047F to the control word and 8192 to the setpoint, and the motor does not move. Bit 6 of the status word is set. That bit is “switching on … Read more
Several drives faulting F004 in the same second is a supply problem. How to work out the bus volts, log the sag safely, and read the trace it gives you.
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.
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
