Hello I have a customer with a hardware configuration depicted in the attachedp PDF. When the MM440 is turned on (to run a cooling fan in this app), they get occaisional faults on the drive for overvoltage on the DC bus. they are using dynamic braking. Sometimes they get zero values in the PIW for all the inputsin rack chassis 3 node 12. Is it possible the faults on the drive are related to the missing PIW data? If a remote I/O looses comms intermittently, will the PIW data be lost or set to 0 or will it retain the last value? John AttachmentVisio-Network Diagram Rev D_LWH.pdf (105 Downloads) |
