7 -16* Displayed after autotuning has been completed. For constants in which no error is detected, the settings are reset to the values determined by autotuning. Errors when Using the Digital Operator Copy FunctionThe errors that can occur when using the copy function from the Digital Operator are given in the followingtable. An error code will be displayed on the Digital Operator. If a Digital Operator key is pressed when anerror code is being displayed, the display will be cleared and 03-01 will be displayed. The error contact outputand alarm output will not function.PG DisconnectionDetectedPG pulses were input when the Inverterwas outputting a frequency. Fix the broken/disconnected wiring.V/f settings exces-sive *(detected only forrotational autotuning)The torque reference exceeded 100%and the no-load torque exceeded 70%during autotuning.• Check and correct the settings.• Disconnect the load from the motor.Motor core satura-tion error (detectedonly for rotationalautotuning)The results of autotuning has exceededthe setting range for a user constant so atemporary setting was made for themotor core saturation coefficient.• Check the input data.• Check motor wiring.• If the motor is connected to themachine, disconnect it.Rated current settingalarm* The rated current is set high.Check the input data (particularly themotor output current and motor ratedcurrent).Adjusted slip valuefell below lower limitAs a result of stationary autotuning 1,the slip value has fallen to 0.2 Hz orbelow.• Check the input data.• If rotational autotuning is possible,perform it. If impossible, perform sta-tionary autotuning 2.Table 7.5 Errors during Copy FunctionFunc-tion Display Meaning Probable causes Corrective ActionsReadDigital Operatorwrite-protectedo3-01 was set to 1 to write a constantwhen the Digital Operator was write-protected (o3-02 = 0).Set o3-02 to 1 to enable writing con-stants with the Digital Operator.Illegal read dataThe read data length does not agree.
