lines (U, V and W). The motor rotation direction can 
be changed by QUICK/JOG on the keypad. Refer to 
parameter P07.02. 
Note: When the function parameter comes back to 
the default value, the motor’s running direction will 
come back to the factory default state, too. In some 
cases it should be used with caution after 
commissioning if the change of rotation direction is 
disabled.   
2: Forbid to run in reverse direction: It can be used in 
some special cases if the reverse running is 
disabled. 
The advantage of high carrier frequency: ideal 
current waveform, little current harmonic wave and 
motor noise.   
The disadvantage of high carrier frequency: 
increasing the switch loss, increasing inverter
