5.6 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 5.12 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 5.12 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.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 H1-01 to H1-07.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.The Up command was set but the Down commandwas not, or vice versa (settings 10 vs. 11) Properly set the functions that required for use in combination with other functions.• Run/Stop command for a 2-wire sequence wasset (H1-oo = 42), but Forward/Reversecommand (H1-oo = 43) was not• “Drive Enable” is set to multi-function input S1or S2 (H1-01 = 6A or H1-02 = 6A)Properly set the functions that required for use in combination with other functions.Two of the following functions are setsimultaneously:• Up/Down Command (10 vs. 11)• Hold Accel/Decel Stop (A)• Analog Frequency Reference Sample/Hold (1E)• Offset Frequency 1, 2, 3 Calculations (44, 45,46)• Check if contradictory settings have simultaneously been assigned to the multi-function inputterminals.• Correct setting errors.The Up/Down command (10, 11) and PI control(b5-01) are enabled simultaneously Set b5-01 to 0 to disable control PI or disable the Up/Down command.5.6 Programming ErrorsYASKAWA ELECTRIC TOEP C710616 45F YASKAWA AC Drive – Z1000 User Manual 2275 Troubleshooting
