6. Motor menu
In this menu, the motor connected to the frequency converter, and the special parameters needed for the operation of
the motor can be set.
Followings can be set here:
•
nominal motor data,
•
cooling mode,
•
torque and motor current limits,
•
tilt prevention,
•
motor test,
•
parameters of the vector mode,
•
control modes
Submenu Explanation, further submenus Values Default setting Unit
6-1 Pn
nominal power
Nominal output power of the motor.
To be set accurately for the torque limitation. type-dependent type-dependent kW
6-2 Un
nominal
voltage
The nominal line voltage of the motor.
If fmotor
≥ fn, this voltage gets to the motor.
This item sets the upper voltage corner point of the
U/f curve.
90,0 - 440,0V

6-3 fn
nominal
frequency
The frequency belonging to the nominal voltage.
This item sets the upper frequency corner point of
the U/f curve. 25,0 - 1000,0 50 Hz
6-4 In
nominal
current
Nominal motor current. The 100% thermal model
belongs to this! The value of this current modified
with the current limit can develop as a maximum,
if it is lower than the I inverter limit! type-dependent type-dependent A
6-5 nn
nominal
rotation speed
The rotation speed at nominal load. At the displays
it can be used as orientation data in function of the
load. 100 - 30000 1450 f/min
6-6
cooling type
For the thermal modelling of the motor.
In case of forced cooling, even at low frequencies
(below 10 Hz), the motor can be durably loaded up
to the nominal torque. Beyond them, the thermal
time constant of the motor depends also on the
size of the motor, that is on Pn. internal

6-7
limit
6-7-1 current
The current value the frequency converter does
not permit to exceed. It modifies the frequency in
order to reduce the load, or it stops with error
message, if the load does not decrease or the tilt
prevention is disabled. The 500% cannot always
be utilized, because this depends also on the
motor data and the maximum capability of the
frequency converter!
100% means the nominal motor current.
10 - 500 110 %
6-7-2 torque
The torque value the frequency converter does not
permit to exceed. It modifies the frequency in order
to reduce the load, or it stops with error message,
if the load does not decrease or the tilt prevention
is disabled. The 500% cannot always be utilized,
because this depends also on the motor data and
the maximum capability of the frequency
converter!
100% means the motor current producing nominal
torque.
