8.8 Basic Parameters
P1 N_rated
Rated frequency value (speed pre-selection) for the motor (input on control panel).
By means of parameter P8-speed display, this parameter can be changed from frequency display to speed
display. The number of motor poles P96-no. of poles is taken into account. Here, only values between the
min. frequency P41-f_mot_min and the max. frequency P42-f_mot_max can be set.
Minimum value: 30 Hz
Maximum value: 4,000 Hz
Factory setting: 83 Hz
P7 select operation
Selection of the source from which the inverter is to be operated with start/stop, setpoint speed value and
torque limitation. The digital and analogue output values are always output independently of the setting.
Values: PC application - Operation occurs via the PC-software
Selection - The inputs for start/stop, speed value and current limitations
can be selectively chosen separate over parameters
P140...P142
Factory setting: Selection
P8 speed display
Selection of the display for rated and actual motor speeds, in Hz or in rpm, the conversion of the
frequency into the speed is performed by the following formula:
Speed = frequency*60/number of poles/2 of the motor (P96-no. of poles).
Values: in Hz - the display is in Hz
in rpm - the display is in rpm (revolutions per minute)
Factory setting: in Hz
8.9 Display Values
P10 N_rated_act (display value)
The valid rated speed value can originate from various sources depending on configuration (PC, remote
control analogue input, remote control fixed frequency input). The currently valid value, i.e. the value
transmitted to the motor control, is displayed for the user via parameter P10.
By means of parameter P8-speed display, this parameter can be changed from frequency display to speed
display, the number of motor poles P96-no. of poles being taken into account.
P11 I_limit_act (display value)
The valid torque limitation may originate from P44-I_limit. The currently valid value is displayed for the
user via the parameter P11.
P13 f_out_act (display value)
f_out_act the current output frequency of the inverter (inverter frequency).
P14 f_motor (display value)
f_motor is the current motor frequency ,is the same as the output frequency (P13-f_out_act).
By means of parameter P8-speed display, this parameter can be changed from frequency display to speed
display, the number of motor poles P96-no. of poles being taken into account.
