9 TroubleshootingYASKAWA ELECTRIC SIEP C730600 23C V1000 Option SI-P3/V Technical Manual 439 Troubleshooting Drive-Side Error CodesDrive-side error codes appear on the drive LED operator. Causes of the errors and corrective actions are listed inTable 19. For additional error codes that may appear on the LED operator screen, refer to the V1000 Technical Manual. FaultsbUS (PROFIBUS-DP Option Communication Error) and EF0 (External Fault Input from the PROFIBUS-DP Option)may appear as an alarm or a fault. When a fault occurs, the digital operator LEDs remain lit. When an alarm occurs, thedigital operator LEDs flash and the “ALM” light illuminatesIf communication stops while the drive is running, check the following items to resolve the fault:• Is the PROFIBUS-DP Option properly installed?• Is the communication line properly connected to the PROFIBUS-DP Option? Is it loose?• Is the controller program working? Has the controller CPU stopped?• Did a momentary power loss interrupt communications?Table 19 Fault Display and Possible SolutionsLED Operator Display Fault NamebUSPROFIBUS-DP Option Communication Error• After establishing initial communication, the connection was lost• Only detected when the run command or frequency reference is assigned to the option (b1-03= 3 or b1-02 = 3)Cause Possible SolutionMaster controller (PLC) has stoppedcommunicating. Check for faulty wiring.Correct any wiring problemsCommunication cable is not connected properlyA data error occurred due to noise• Check the various options available to minimize the effects of noise.• Take steps to counteract noise in the control circuit wiring, main circuit lines, and groundwiring.• If a magnetic contactor is identified as a source of noise, install a surge absorber to thecontactor coil• Use cables recommended by Yaskawa, or another type of shielded line. Ground the shield onthe controller side and on the PROFIBUS-DP Option sidePROFIBUS-DP Option is damaged. If there are no problems with the wiring and the error continues to occur, replace thePROFIBUS-DP OptionLED Operator Display Fault NameEF0 External Fault Input from PROFIBUS-DP OptionThe alarm function for an external device has been triggeredCause Possible SolutionAn external fault is being sent from the uppercontroller (PLC).• Remove the cause of the external fault• Reset the external fault input from the upper controller (PLC) deviceProblem with the upper controller (PLC)program. Check the program used by the upper controller (PLC) and make the appropriate correctionsLED Operator Display Fault NameoFA00 PROFIBUS-DP Option Fault (Port A)PROFIBUS-DP Option is not properly connectedCause Possible SolutionNon-compatible option connected to the drive. Connect an option that is compatible with the driveLED Operator Display Fault NameoFA01 PROFIBUS-DP Option Fault (Port A)PROFIBUS-DP Option is not properly connectedCause Possible SolutionProblem with the connectors between the driveand PROFIBUS-DP Option. Turn the power off and check the connectors between the drive and PROFIBUS-DP Option.
