P-0-0576, Search mode: finding point slip factor
Input min/max: Default value: Unit:
MPB: -320,00 / 320,00 100,00 %
The search mode function is selected via P-0-0045, Control word of
current controller. As soon as the machine has been found the rated slip
is added to the speed at the "finding point". 100% are corresponding to
the rated slip of the machine.
With clockwise rotating field: V = V
finding point
+ (V
slip
* P-0-0576 / 100%)
With anti-clockwise rotat. field: V = V

- (V

* P-0-0576 / 100%)
P-0-0577, Square characteristic: lowering factor
Input min/max: Default value: Unit:
MPB: 0,00 / 100,00 50,00 %
The square characteristic is selected via P-0-0045, Control word of
current controller. The degree of lowering in the basic range of setting is
trimmed with this parameter.
The value of 100% corresponds to the original square curve. When the
percentage value becomes lower, this lowering factor is reduced until the
setting 0% has been reached which corresponds to the linear
characteristic.
P-0-0590, Motor model frequency loop proportional gain
Input min/max: Default value: Unit:
MPB: 0,00 / 655,35 10,00 %
This parameter only takes effect in conjunction with field-oriented current
control without encoder. Together with P-0-0591, Motor model
frequency loop integral action time, parameter P-0-0590 is used to
parameterize the "frequency loop".
By means of the differences between motor model and measured
currents, the frequency loop determines the current rotational frequency
of the motor shaft. The output of the frequency loop supplies parameter
S-0-0040, Velocity feedback value and is transmitted according to the
velocity loop.
Note: Field-oriented current control without encoder is activated via
P-0-0045, Control word of current controller. If the
functional package "closed-loop" is active, "operation without
encoder" has to be set in P-0-0074, Encoder type 1 (motor
encoder)!
