attenuate.
2) Better cooling effect. During flux braking, the
stator current of the motor increases, while the
rotor current does not change, while the cooling
effect of stator is much more effective than that of
the rotor.

STO lock
0: STO alarm lock
Alarm-lock means STO alarm must be reset after
state restoration when STO occurs.
1: STO alarm unlock
Alarm-unlock means when STO occurs, after state
restoration, STO alarm will disappear
automatically.

Enabling auto
carrier frequency
reduction
0: Disable
1: Enable
Note: Automatic carrier frequency reduction
indicates that the inverter automatically reduces
the carrier frequency when detecting the heat sink
temperature exceeds the rated temperature. When
the temperature decreases to a certain degree, the
carrier frequency recovers. This function reduces
the chance of inverter overheat alarm.
