DESCRIPTION OF PARAMETERS
7.1 Basic Parameters
P2.1.1 Minimum frequency ID101
“Min Frequency”
Defines minimum frequency of any adjustable reference input (i.e. when 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
“Max Frequency”
Defines maximum frequency limit both negative and positive directions.
Direction dependent frequency limits can be given in
“
G: Limit Settings \ Frequency
Handling
”
.
Note: When the AC drive is in run state, do not change this parameter to a value lower
than the current output frequency. The change will be executed without ramp.
Note: Max and Min frequencies are used for several scaling functions and are not
intended to be adjusted dynamically. Never set maximum frequency to same value or a
value below the minimum frequency. When changing the maximum frequency in Marine
application, do not give any other command to the drive for 2 seconds so that the
software can process the change properly.
P2.1.3 Motor Nominal Voltage ID110
“Motor Nom Voltg”
Find this value U
n
on the rating plate of the motor.
P2.1.4 Motor Nominal Frequency ID111
“Motor Nom Freq”
Find this value f
n
on the rating plate of the motor. This parameter sets the field
weakening point to the same value
in “G: Motor Control
\
U/f Settings”
.
P2.1.5 Motor nominal speed ID112
“Motor Nom Speed”
Find this value n
n
on the rating plate of the motor. Note also nominal frequency.
In some cases, the motor nominal speed is shown with one decimal. In this case the
practice is to give the nearest integer number and adjust the motor nominal frequency so
that the drive will calculate correct [FW]PolePairNumber.
P2.1.6 Motor nominal current ID113
“Motor Nom Currnt”
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.
P2.1.7 Motor cos phi ID120
“Motor Cos Phi”
Find this value “cos phi” on the rating plate of the motor.
