RISK OF DAMAGE TO THE DRIVE
On ATV12
pppp
M2 ratings, if the filters are disconnected, the drive’s switching frequency must not exceed 4 kHz.
Failure to follow these instructions can result in equipment damage.

The motor switching frequency will always be modified (reduced) when the internal temperature of the
drive is too high.

HF1: Heating optimization.
Allows the system to adapt the switching frequency according to the motor frequency.
Allows the system to adapt the switching frequency according to the motor frequency.

HF2: Motor noise optimization (for high switching fequency).
Allows system to keep a constant chosen switching frequency (SFr) whatever the motor frequency (rFr).
