46Warning FunctionsThe warning functions in parameters 221 through 228 are not activeduring ramp-up after a Start command, ramp down after a Stopcommand, or while stopped. The warning functions are activated whenthe output frequency has reached the resulting reference.The signal outputs can be programmed to generate a warning signalvia terminal 42 or 45 and via the relay outputs.The reference limits in parameter 226, Warning: High Reference andparameter 227, Warning: Low Reference are only active when remotereference has been selected.221 Warning: Low Current (WARN. LOW CURR)Value:0.0 to parameter 222 Warning: High current ✭ 0.0 AFunction:When the motor current is below the limit programmed in this parameter,the display shows a flashing CURRENT LOW, provided Warning hasbeen selected in parameter 409, Function in Case of No Load. Thedrive will trip if parameter 409 has been selected as Trip. This can beused to indicate when a belt between the motor and the driven load isbroken.Description of choice:The lower signal limit must be programmed within the normal workingrange of the drive.222 Warning: High Current (WARN. HIGH CURR)Value:Parameter 221 to rated current Rated currentFunction:If the motor current is above the limit programmed in this parameter, thedisplay shows a flashing CURRENT HIGH.Description of choice:The upper signal limit of the motor frequency must be programmedwithin the normal working range of the drive. See the drawing atparameter 221, Warning: Low Current.223 Warning: Low Frequency(WARN. LOW FREQ)Value:0.0 to parameter 224 0.0 HzFunction:If the output frequency is below the limit programmed in this parameter,the display will show a flashing F OUT < FLOW.Description of choice:The lower signal limit of the motor frequency must be programmedwithin the normal working range of the drive. See drawing at parameter221 Warning: Low current.224 Warning: High Frequency(WARN. HIGH FREQ.)Value:Par. 200 Output frequency range = 0 to 120 Hzparameter 223 - 120 Hz ✭ 120.0 HzPar. 200 Output frequency range = 0 to 1000 Hzparameter 223 - 1000 Hz ✭ 120.0 HzFunction:If the output frequency is above the limit programmed in this parameter,the display will show a flashing F OUT > F HIGHDescription of choice:The higher signal limit of the motor frequency must be programmedwithin the normal working range of the drive. See the drawing atparameter 221, Warning: Low Current.✭ Indicates default parameter. Depending upon the application, the drive may be delivered with other parameters selected.
