CAUTION
RISK OF DAMAGE TO THE MOTOR AND THE DRIVE
• Check that the motor will withstand this current, particularly in the case of permanent magnet synchronous
motors, which are susceptible to demagnetization.
• Check that the profile mission complies with the derating curve given in the installation manual.
Failure to follow these instructions can result in equipment damage.
First current limitation.
Note: If the setting is less than 0.25 In, the drive may lock in [Output Phase Loss] (OPL) fault mode if this has been enabled
(see page 238
). If it is less than the no-load motor current, the motor cannot run.
SFt [Switch. freq type]
[SFR type 1] (HF1)
HF1
HF2
The motor switching frequency will be modified (reduced) when the internal temperature of the drive will be too high.
[SFR type 1] (HF1): Heating optimization
Allows the system to adapt the switching frequency according to the motor frequency.
[SFR type 2] (HF2): Motor noise optimization (for high switching frequency)
Allows the system to keep a constant chosen switching frequency [Switching freq.] (SFr) whatever the motor frequency
[Output frequency] (rFr).
In the event of overheating, the drive automatically decreases the switching frequency.
It is restored to its original value when the temperature returns to normal.

CAUTION
RISK OF DAMAGE TO THE DRIVE
On ATV32
ppppM2 ratings, if the RFI filters are disconnected (operation on an IT system), the drive’s switching
frequency must not exceed 4 kHz.
Failure to follow these instructions can result in equipment damage.
Switching frequency setting.
Adjustment range: The maximum value is limited to 4 kHz if [Motor surge limit] (SUL) parameter page 107
is configured.
Note: In the event of excessive temperature rise, the drive will automatically reduce the switching frequency and reset it once
the temperature returns to normal.
In case of high speed motor, it is advised to increase the pwm frequency [Switching freq.] (SFr) at 8, 12 or 16 kHz.
