I SLIP COMPENSAT
G19.2.7 / Current
limit factor
0.0 – 20.0%
Modifies the speed by reducing the output frequency to keep the output current
within a controllable margins (display shows ILT). Adjusting this parameter can
improve the stability of the current limit function taking the motor slip into account.
Note: The following table shows the default values for drives of any nominal
voltage.

* Adjust mode: When initializing factory settings (1) or manually modifying the
Motor Nominal Power (G2.3) (2). The value of the current limit factor is initialized
according to the table. Values outside the table are estimated according to the
table.
In all cases the adjustment range is + / -30% of initialized value in any of the two
scenarios given (1) and (2).
Note: We recommend this value is adjusted only when the current limit action is
unstable. A low value will improve the stability although the current limit action will
operate earlier.
YES
9 STR FRQ = 0.0%
START FREQUENCY
G19.2.9 / Initial
frequency

Allows setting of an initial frequency that will be applied from the drive at the
moment of starting.
YES

OFF=0.0,
OFF(40%) to
70%
In some motors, instable behaviours are generated at low frequencies when the
motors are connected with no load. In that case, set this parameter to 65% as
initial value. If oscillations still are present, reduce the value.
YES
11 DAMPfilt=0.0%
G19.2.11 /
Damping filter
0.0 to 10.0%
This filter controls the instability. If the value of the parameter 19.2.10 is reduced
down to 45 % and the instability problems are not solved, increase the value of
this parameter.
YES
