Varispeed AC Protective Functions Operation Errors An operation error will occur if there is an invalid setting or a contradiction between two parameter settings. The MxC cannot be started until the parameters have been correctly set (the alarm output and fault contact outputs will not operate either). 19 Alarm Display Meaning PID Feedback Reference Lost FBL (Flashing) FBL Feedback Loss A PID feedback reference loss was detected (b5-12=2) and the PID feedback input was less than b5-13 (PID feedback loss detection level) for longer than the time set in b5-14 (PID feedback loss detection time).
MEMOBUS Communications Error CE (Flashing) CE MEMOBUS Com Err Normal reception was not possible for 2 s or longer after received control data. Option Card Communications Error BUS (Flashing) BUS Option Com Err A communications error occurred in a mode where the Run Command or a frequency reference is set from an communications option card. Communications on Standby CALL (Flashing) CALL Com Call Control data was not normally received when power was turned on. Error Display Meaning Incorrect MxC Capacity Setting OPE01 OPE01 kVA Selection The MxC capacity setting doesn't match the MxC being used. Contact your Yaskawa representative.
Parameter Setting Range Error OPE02 OPE02 Limit The parameter setting is outside of the valid setting range. Multi-Function Input Selection Error OPE03 OPE03 Terminal Multi-Function Input Selection Error Option Card Selection Error OPE05 OPE05 Sequence Select The option card was selected as the frequency reference source by setting b1-01 to 3, but an option card isn't connected (C option). Control Method Selection Error OPE06 OPE06 PG Opt Missing Flux Vector Control was selected by setting A1-02 to 3, but a PG Speed Control Card isn’t connected.
Multi-Function Analog Input Selection Error OPE07 OPE07 Analog Selection The same setting is selected for the analog input selection and the PID function selection. Parameter Selection Error OPE08 OPE08 Ctrl Func Error A setting has been made that is not required in the current control method. PID Control Selection Error OPE09 OPE09 PID Select Error PID Control Selection Error V/f Data Setting Error OPE10 OPE10 V/f Ptrn Setting Parameters E1-04, E1-06, E1-07, and E1-09 do not satisfy the following conditions:
E1-04 (FMAX) ≥ E1-06 (FA) > E1-07 (FB) ≥ E1-09 (FMIN) E3-02 (FMAX) ≥ E3-04 (FA) > E3-05 (FB) ≥ E3-07 (FMIN) Default Error OPE20 OPE20 Factory Setting Err The defaults were not set replacing the control card. EEPROM Write Error ERR ERR EEPROM R/W Err A verification error occurred when writing EEPROM.
