User Manual of EM760 High-Performance Inverter Set the ones place ofF27.03 to 1: terminal reset Terminal reset: The feedforward gain is reset by the terminal. Set the tens place ofF27.03 to 0: save after power failure Save after power failure: When the feedforward gain is powered off and then powered on, the value before power failure will be restored. Set the tens place ofF27.03 to 1: not save after power failure Not save after power failure: When the feedforward gain is powered off and then powered on, the initial feedforward gain will be restored. Set the hundreds place of F27.03 to 0: not calculate (only for the straight wire drawing machine) No calculation:
When the DI input function “26: frequency source switching” of the external terminal is enabled, the feedforward calculation will not be continued. Set the hundreds place ofF27.03 to 1: calculate (only for the straight wire drawing machine) No calculation: When the DI input function “26: frequency source switching” of the external terminal is enabled, the feedforward calculation will be continued. Upper limit of feedforward gain setting or change Initial value of feedforward gain Under normal circumstances, it is not necessary to set the filtering of feedforward gain.
