Code Name/Description Setting range Factory settings
Ftd [Freq. threshold] 0 to 599 Hz [High speed] (HSP)
Frequency threshold of the function [thresh. freq. err.] (FtA) , that is assigned to a relay or a logic output ( see "R1 CONFIGURATION" on page
176 ) or that is used by the
[SET SWITCHING]
(MLP-) function ( see "PARAMETER SWITCH (MLP-)" on page 270 ).
F2d [Freq. threshold 2] 0 to 599 Hz [High speed] (HSP)
Frequency threshold of the function
[thresh. freq. 2 err.]
(F2A) , that is assigned to a relay or a logic output ( see "R1 CONFIGURATION" on page
176 ) or that is used by the [SET SWITCHING] (MLP-) function ( see "PARAMETER SWITCH (MLP-)" on page 270 ).
FFt [Freewheel stop Thd.] 0 to 599 Hz 0 Hz
see "STOP MODE (Stt-)" on page 206
This parameter supports switching from a ramp stop or a fast stop to a freewheel stop below a low speed threshold.
It can be enabled if [STOP MODE] (Stt) = [Fast stop] (FSt) or [ramp stop] (rMP) ).
• 0.0: No transition into freewheel stop.
• 0.1 to 599 Hz: Frequency threshold at which the motor goes into freewheel stop.
ttd [Motor therm. level] 0 to 118% 100%
see "THERM. MOTOR PROTECTION (tHt) and LOSS OF MOTOR PHASE (OPL)" on page 292 .
Trip threshold for motor thermal alarm (logic output or relay)
JPF [Skip frequency] 0 to 500 or 599 Hz, de-
pending on the size
0 Hz
Skip frequency. This parameter prevents prolonged operation within an adjustable range around the regulated frequency. This function can be
used to prevent a critical speed, which would cause resonance, being reached. Setting the function to 0 renders it inactive.
JF2 [Skip frequency 2] 0 to 500 or 599 Hz, de-
pending on the size
0 Hz
2nd skip frequency. This parameter prevents prolonged operation within an adjustable range around the regulated frequency. This function can
be used to prevent a critical speed, which would cause resonance, being reached. Setting the function to 0 renders it inactive.
JF3 [3rd Skip Frequency] 0 to 500 or 599 Hz, de-
pending on the size
0 Hz
3rd skip frequency. This parameter prevents prolonged operation within an adjustable range around the regulated frequency. This function can
be used to prevent a critical speed, which would cause resonance, being reached. Setting the function to 0 renders it inactive.
JFH [Skip Frequency Hyst.] 0.1 to 10 Hz 1 Hz
The parameter is visible if at least one skip frequency [skip frequency] (JPF) , [skip frequency 2] (JF2) or [skip frequency 2] (JF3) is not
equal to 0.
Area for the skip frequency: From (JPF - JFH) to (JPF + JFH), for example.
This setting applies to all 3 frequencies JPF, JF2 and JF3 together.
LbC [Load sharing correction] 0 to 599 Hz 0
Nominal compensation in Hz
trt
[Torque coeff]
0 to 1000% 100%
Factor applied to [Torq. Ref.] (tr1) .
These parameters only appear if the corresponding function has been selected in another menu. When the parameters can also be
accessed and adjusted from within the configuration menu for the corresponding function, their description is detailed in these menus, on
the pages indicated, to aid programming.
Parameter that can be modified during operation or when stopped.
