7 Troubleshooting ENGLISH An Operator Programming Error (OPE) occurs when an inapplicable parameter is set or an individual parameter setting is inappropriate. When an OPE error is dis- played, press the ENTER button to display U1-18 (OPE fault constant). This monitor will display the parameter that is causing the OPE error. ‹ Operator Programing Errors I67E-EN V1000 Quick Start Guide 29 LED Display ALM FLT Cause Controller Undervoltage The drives controller power supply voltage is too low. DC Charge Circuit Fault The charge circuit for the DC bus is broken. LED Operator Display Cause Corrective Action oPE01 Drive capacity and value set to o2-04 do not match.
Correct the value set to o2-04. oPE02 Parameters were set outside the allowable setting range. Set parameters to the proper values. oPE03 A contradictory setting is assigned to multi- function contact inputs H1-01 through to H1- 07. • The same function is assigned to two inputs (this excludes “External fault” and “Not used”) • Input functions which require the setting of other input functions were set alone. • Input functions that are not allowed to be used simultaneously have been set. • Fix any incorrect settings. • Refer to the instruction manual for more details. oPE05 • The run command source (b1-02) or fre- quency reference source (b1-01) is set to 3 but no option board is installed.
• The frequency reference source is set to pulse input but H6-01 is not 0. • Install the required option board. • Correct the values set to b1-01 and b1-02. oPE07 Settings to multi-function analog inputs H3- 02 and H3-10 and PID functions conflict. • H3-02 and H3-10 are set to the same value (this excludes settings “0” and “F”) • PID functions have been assigned to both analog inputs and the pulse input at the same time. • Fix any incorrect setting. • Refer to the instruction manual for more details. oPE08 A function has been set that cannot be used in the control mode selected (might appear after control mode change) • Fix any incorrect setting.
• Refer to the instruction manual for more details. oPE10 The V/f pattern setting is incorrect. • Check the V/f pattern settings. • Refer to the instruction manual for more details.
