So kindly provide a solution that how to use the DTI card or how to parameterize the Drive so that the purpose can be served. Its showing a fault numbered F31117 Inversion Error signal for A & B Track. For you reference i am attaching the Starter project. Attachment N2_BRIDLE_ROLLS_11052011.zip (270 Downloads)

Because DTI has two opto outputs 5V and 24V.Since in FM350 you cannot use 5V pulses. 2) If it is FM450, then you can use 5V pulses for FM but , in that case you have to arrange 5V supply for DTI card. The best option would be parallel the 24V pulses for both drive and FM or use pulse splitter card. I have used this configuration for continous galvanizing lines where FM is used to track the weld metal detector. Thnks Ahmed
