MARINE APPLICATION DESCRIPTION OF PARAMETERS7.1 Basic ParametersP2.1.1 Minimum frequencyID101Defines minimum frequency of any adjustable reference input (i.e. reference is not aparameter). Minimum frequency is bypassed when jogging speed, preset speed orinching reference is used.P2.1.2 Maximum frequencyID102Defines maximum frequency limit both negative and positive directions.Direction dependent frequency limits can be given in G: Limit Settings \ FrequencyHandling .Note: Do not change this parameter to lower value that current output frequency ifchanged during running. The change will be executed without ramp.Note: Max and Min frequencies are used for several scaling functions and are not mendto be adjusted dynamically. Never set maximum frequency to same or below minimumfrequency. When changing maximum frequency in Marine application do not give anyother command to drive for 2 seconds that change can be processed properly bysoftware.Drive Synch operationThe maximum recommended frequency is 100 Hz.P2.1.3 Motor Nominal VoltageID110Find this value Un on the rating plate of the motor.P2.1.4 Motor Nominal Frequency ID111Find this value fn on the rating plate of the motor. This parameter sets the fieldweakening point to the same value \ .P2.1.5 Motor nominal speedID112Find this value nn on the rating plate of the motor. Note also nominal frequency.Some cases motor nominal speed is shown with one decimal. In this case the practice isto give nearest integer number and adjust motor nominal frequency so that drive willcalculate correct [FW]PolePairNumber.P2.1.6 Motor nominal currentID113Find this value In on the rating plate of the motor. If magnetization current is provided setalso Magnetization current P2.1.9 before identification run.DriveSynch OperationMotor Nominal current from the motor name plate / Number of drives in parallel usingVacon Drive Synch.
