6.6 Operator Programming ErrorsYASKAWA ELECTRIC SIEP C710616 27C YASKAWA AC Drive A1000 Technical Manual 325Troubleshooting66.6 Operator Programming Errors◆ oPE Codes, Causes, and Possible SolutionsAn Operator Programming Error (oPE) occurs when a contradictory parameter is set or an individual parameter is set toan inappropriate value.The drive will not operate until the parameter or parameters causing the problem are set correctly. An oPE, however, doesnot trigger an alarm or fault output. If an oPE occurs, investigate the cause and Refer to oPE Codes, Causes, andPossible Solutions on page 325 for the appropriate action. When an oPE appears on the operator display, press theENTER button to view U1-18 and see the parameter that is causing the oPE error (U1-18).Table 6.17 oPE Codes, Causes, and Possible SolutionsDigital Operator 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 actual capacity of the drive are not the same. Correct the value set to o2-04.Digital Operator Display Error NameoPE02 Parameter Range Setting ErrorUse U1-18 to find parameters set outside the range.Cause Possible SolutionsParameters were set outside the possible setting range. Set parameters to the proper values.Note: When multiple errors occur at the same time, other errors are given precedence over oPE02.Digital Operator Display Error NameoPE03 Multi-Function Input Selection ErrorA contradictory setting is assigned to multi-function contact inputs H1-01 to H1-08.Cause Possible Solutions• The same function is assigned to two multi-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 command was not, or vice versa (settings 10 vs. 11).Correctly set functions that need to be enabled in combination with other functions.The Up 2 command was set but the Down 2 command was not, or vice versa (settings 75 vs.76).• Run/Stop command for a 2-wire sequence was set (H1- = 42), but Forward/Reversecommand (H1- = 43) was not.• “Drive Enable” is set to multi-function input S1 or S2 (H1-01 = 6A or H1-02 = 6A).Correctly set functions that need to be enabled in combination with other functions.• Two of the following functions are set at the same time:• Up/Down Command (10 vs. 11)• Up 2/Down 2 Command (75 vs. 76)• 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 been assigned to the multi-function input terminals atthe same time.• Correct setting errors.The Up/Down command (10, 11) is enabled at the same time as PID control (b5-01). Disable control PID (b5-01 = 0) or disable the Up/Down command.Settings for N.C. and N.O. input for the following functions were selected at the same time:• External Search Command 1 and External Search Command 2 (61 vs. 62)• Fast Stop N.O. and Fast Stop N.C. (15 vs. 17)• KEB for Momentary Power Loss and High Slip Braking (65, 66, 7A, 7B vs. 68)• Motor Switch Command and Accel/Decel Time 2 (16 vs. 1A)• KEB Command 1 and KEB Command 2 (65, 66 vs. 7A, 7B)• FWD Run Command (or REV) and FWD/REV Run Command (2-wire) (40, 41 vs. 42, 43)• External DB Command and Drive Enable (60 vs. 6A)• Motor Switch Command and Up 2/Down 2 Command (16 vs. 75, 76)Check for contradictory settings assigned to the multi-function input terminals at the sametime. Correct setting errors.One of the following settings was entered while H1- = 2 (External Reference 1/2):• b1-15 = 4 (Pulse Train Input) but the pulse train input selection is not set for the frequencyreference (H6-01 > 0)• b1-15 or b1-16 set to 3 but no option card is connected• Although b1-15 = 1 (Analog Input) and H3-02 or H3-10 are set to 0 (Frequency Bias) Correct the settings for the multi-function input terminal parameters.H2- = 38 (Drive Enabled) but H1- is not set to 6A (Drive Enable).H1- = 7E (Direction Detection) although H6-01 is not set to 3 (for V/f Control with PGusing terminal RP as speed feedback input).Digital Operator Display Error NameoPE04 Initialization required.Cause Possible SolutionsThe drive, control board, or terminal board has been replaced and the parameter settingsbetween the control board and the terminal board no longer match.To load the parameter settings to the drive that are stored in the terminal board, set A1-03 to5550. Initialize parameters after drive replacement by setting A1-03 to 1110 or 2220.
