7. MARINE APPLICATION DESCRIPTION OF PARAMETERS
7.1 Basic Parameters
P2.1.1 Minimum frequency ID101
Defines minimum frequency of any adjustable reference input (i.e. reference is not a
parameter). Minimum frequency is bypassed when jogging speed, preset speed or
inching reference is used.
P2.1.2 Maximum frequency ID102
Defines maximum frequency limit both negative and positive directions.
Direction dependent frequency limits can be given in G: Limit Settings \ Frequency
Handling .
Note: Do not change this parameter to lower value that current output frequency if
changed during running. The change will be executed without ramp.
Note: Max and Min frequencies are used for several scaling functions and are not mend
to be adjusted dynamically. Never set maximum frequency to same or below minimum
frequency. When changing maximum frequency in Marine application do not give any
other command to drive for 2 seconds that change can be processed properly by
software.
Drive Synch operation
The maximum recommended frequency is 100 Hz.
P2.1.3 Motor Nominal Voltage ID110
Find this value U
n
on the rating plate of the motor.
P2.1.4 Motor Nominal Frequency ID111
Find this value f
n
on the rating plate of the motor. This parameter sets the field
weakening point to the same value \ .
P2.1.5 Motor nominal speed ID112
Find this value n
n
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 is
to give nearest integer number and adjust motor nominal frequency so that drive will
calculate correct [FW]PolePairNumber.
P2.1.6 Motor nominal current ID113
Find this value I
n
on the rating plate of the motor. If magnetization current is provided set
also Magnetization current P2.1.9 before identification run.
DriveSynch Operation
Motor Nominal current from the motor name plate / Number of drives in parallel using
Vacon Drive Synch.
