(1) 100% corresponds to the nominal torque of a motor with a power rating equal to that associated with the
speed controller for "high torque" applications.
(2) In corresponds to the speed controller nominal current indicated in the catalog and on the speed controller
identification label for "high torque" applications.
(3) Yes if SFt = LF, No if SFt = HF1 or HF2

Sw Freq. Type
LF-HF1-HF2 LF
Used to select a low switching frequency (LF) or a high switching frequency (HF1 or HF2). HF1
switching is designed for applications with a low load factor without derating the speed controller. If
the thermal state of the speed controller exceeds 95 %, the frequency automatically changes to 2
or 4 kHz depending on the speed controller rating. When the thermal state of the speed controller
drops back to 70 %, the selected switching frequency is re-established. HF2 switching is designed
for applications with a high load factor with derating of the speed controller by one rating : the drive
parameters are scaled automatically (torque limit, thermal current, etc).
Modifying this parameter results in the following parameters returning to factory
settings :
• nCr, CLI, Sfr, nrd (Drive menu)
• ItH, IdC, Ibr, Ctd (Adjust menu).

Sw Freq. - kHz

Used to select the switching frequency. The adjustment range depends on the SFt parameter.
If SFt = LF : 0.5 to 2 or 4 kHz acc. to the controller rating
If SFt = HF1 or HF2 : 2 or 4 to 16 kHz acc. to the controller rating
The maximum operating frequency (tFr) is limited according to the switching frequency :

This function with "yes" extends the adjustment range for the UFr parameter in the adjust menu for
adaptation to the special motors mentioned at the start of this section. Can only be accessed in the
"Handling" and "General use" macro-configurations.
