P-07 Motor Nom Voltage 0 / 20 V U
e
Defines the Motor rated voltage.
When the output frequency is greater than the
”Motor Nom Frequency” (P-09), the output voltage
is controlled at the level set with “Motor Nom
Voltage” (P-07).

Motor rated current.
By setting the ”Motor Nom Current” in the drive,
the motor overload protection is configured to
match the motor rating.
When the measured motor current exceeds
“Motor Nom Current”, the decimal points on the
drive display will flash to indicate an overload
condition.
If this condition persists, the drive will eventually
trip, displaying
I.t-trP
, preventing thermal
overload of the motor.

e
P-09 Motor Nom Frequency 25 Hz 500 Hz The rated frequency of the motor.
This is the frequency at which ”Motor Nom
Voltage” is applied to the motor. Below this
frequency, the applied motor voltage will be
reduced. Above this frequency the voltage remains
limited to ”Motor Nom Voltage”
Hint:
If the value for P-09 is changed, the following
parameters will be reset to their default settings:
P-01 f-max
P-02 f-min
P-10 Motor Nom Speed
P-20 f-Fix1
P-21 f-Fix2
P-22 f-Fix3
P-23 f-Fix4
50 Hz
P-10 Motor Nom Speed 0 / 200 rpm 30000 rpm Motor rated speed.
P-10 = 0: the speed of the motor will be displayed
in Hz.
P-10 > 0: the speed related parameters (f-max,
f-min etc.) will be displayed in rpm.
The slip compensation is also activated, where the
shaft speed of the motor is maintained under
varying load conditions by compensating for the
load-dependent slip of the motor.
If “Motor Nom Speed” = motor synchronous speed
(e.g. 3000 rpm for a 2-pole 50Hz motor), the speed
can be displayed in rpm without activating the slip
compensation.

Voltage is used to increase the applied motor
voltage at low output frequency, in order to
improve low speed and starting torque.
Excessive voltage boost levels may result in
increased motor current and temperature, and
forced ventilation may be required. f (FS)
