The inverter displays a warning code when the data set as a target function code satisfies the condition (specified in
the Condition column) in relation to the data set as the corresponding basic function code.
Each parameter (target function code) is readjusted to the data set as the basic function code (by updating at the
inverter start-up).
*1 In this case, the base frequency is rewritten at parameter readjustment. If the base frequency is updated to an
inappropriate value, a motor burnout may result. Therefore, if the warning is displayed, change the current base
frequency data to an appropriate value.
*2 These parameters are checked, even when the digital operator (02) is not specified for the frequency source
setting (A001).
*3 The current value of the jump (center) frequency is updated to "'the current value of the jump frequency' - 'value of
the Jump (hysteresis) frequency width (minimum)'".
