Parameter
Notes
P1.1.1
101
Minimum frequency
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.
P1.1.2
102
Maximum frequency
Defines maximum frequency limit both negative and positive directions. Direction
dependent frequency limitscan be given in “G: Limit Settings\Frequency Handling”.
Drive synch operation
The maximum recommended frequency is 100 Hz.
Do not change this parameter to
lower value that current output
frequency if changed during
running. The change will be
executed without ramp.
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
SPX Advanced application do not
give any other command to drive
for 2 seconds that change can be
processed properly by software.
P1.1.3
110
Motor nominal voltage ““Motor nom voltg”
Find this value U
n
on the rating plate of the motor.
P1.1.4
111
Motor nominal frequency “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”
P1.1.5
112
Motor nominal speed “Motor nom speed”
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]Pole Pair Number.
P1.1.6
113
Motor nominal current “Motor nom currnt”
Find this value I
n
on the rating plate of the motor. If magnetization current is provided
set also Magnetization current P1.1.9 before identification run.
Drive synch operation
Motor Nominal current from the motor name plate/Number of drives in parallel using
Drive Synch.
P1.1.7
120
Power factor “Motor PF”
Find this value “cos phi” on the rating plate of the motor.
P1.1.8
116
Motor nominal power ““Motor nom power”
Find this value on the rating plate of the motor.
Drive synch operation
Motor Nominal power from the motor name plate/Number of drives in parallel using
Drive Synch.
P1.1.9
612
Magnetizing current “Magn current”
Set here the motor magnetizing current (no-load current).
Can be measured by running motor without load at 2/3 of nominal speed.
When value is zero the magnetization current is calculated from motor nominal
parameters
Motor Magnetization Current =
*Motor Nominal Current
Motor Magnetization Current =
*Motor Nominal Current
[FW]RotorFlux =
(when f(Out)> f(MotorNomFreq)
If given before identification run this is used as reference for U/f tuning when making
identification without rotating the motor.
DriveSynch Operation
Motor nominal magnetization current/number of drives in parallel using Drive Synch.
