6.6 Programming Errorsu Programming Error Codes, Causes, and Possible SolutionsA Programming Error (oPE) occurs when a contradictory parameter is set or an individual parameter is set to an inappropriatevalue.The drive will not operate until the parameter or parameters causing the problem are set correctly. An oPE, however, does nottrigger an alarm or fault output. If an oPE occurs, investigate the cause and refer to Table 6.10 for the appropriate action. Whenan oPE appears on the HOA keypad display, press the ENTER button to view U1-18 and see which parameter is causing theoPE.Table 6.10 oPE Codes, Causes, and Possible SolutionsHOA Keypad Display Error NameoPE01 Drive Capacity Setting FaultDrive capacity and the value set to o2-04 do not match.Cause Possible SolutionsThe drive model selection (o2-04) and the actualcapacity of the drive are not the same Correct the value set to o2-04.HOA Keypad Display Error NameoPE02 Parameter Range Setting ErrorUse U1-18 to find parameters set outside the range.Cause Possible SolutionsParameters were set outside the possible settingrange• Set parameters to the proper values by checking the modified constants menu and verifying thatsettings are within the limits.• Set Z1-01 to 1 to re-initialize the drive and bypass.Set parameters to the proper values by checking the modified constants menu and verifying thatsettings are within the limits.Note: When multiple errors occur simultaneously, other errors are given precedence over oPE02HOA Keypad Display Error NameoPE03 Multi-Function Input Selection ErrorA contradictory setting is assigned to multi-function contact inputs Z2-01 to Z2-08.Cause Possible Solutions• The same function is assigned to twomulti-function inputs• Excludes “Not used” and “External Fault”• Ensure all multi-function inputs are assigned to different functions.• Re-enter the multi-function settings to ensure this does not occur.Settings for N.C. and N.O. input for the followingfunctions were selected simultaneously:• External Search Command 1 and ExternalSearch Command 2 (61 vs. 62)• Fast Stop N.O. and Fast Stop N.C. (15 vs. 17)• KEB for Momentary Power Loss and High SlipBraking(65, 66, 7A, 7B vs. 68)• KEB Command 1 and KEB Command 2 (65, 66vs. 7A, 7B)• FWD Run Command (or REV) and FWD/REVRun Command (2-wire) (40, 41 vs. 42, 43)• Drive Enable (60 vs. 6A)• Check if contradictory settings have simultaneously been assigned to the multi-function inputterminals.• Correct setting errors.6.6 Programming ErrorsYASKAWA ELECTRIC SIEP YAIZ1B 01E YASKAWA AC Drive – Z1000 Bypass Technical Manual 2516 Diagnostics &Troubleshooting
