FP2 Analog UnitTroubleshooting13 - 413.2 Problems Concerning the Analog Output13.2 Problems Concerning the Analog OutputProblem RemedyProper analog output cannot beobtained.Make sure that the FP2 CPU unit is in RUN mode.Check the I/O allocation for the analog units.Check the range settings.Check the settings for no execution of conversion processing (sharedmemory setting).Make sure that the analog output data given to the analog unit is properfor the range.For current output, make sure that the impedance of the output loaddevice is 300Ω or less.Check the analog signal wiring.Analog output value is unsteady. Make sure that you are using shielded twisted - pair wiring for the outputsignal wires.Make sure that the shielding of the shielded twisted - pair wiring is proper-ly connected.Make sure that no output signal wires are near other power wires.Check the sequence program that gives the output data to the analogunit.Phone: 800.894.0412 - Fax: 888.723.4773 - Web: www.clrwtr.com - Email: info@clrwtr.com
