2: Forbid to run in reverse direction. It can be used in some special cases if the reverse
running is disabled.
Code
F0.14
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 temperature and the impact to the output capacity. The inverter needs to derate
on high carrier frequency. At the same time, the leakage and electrical magnetic
interference will increase.
Applying low carrier frequency is contrary to the above,too low carrier frequency will
cause unstable running,torque decreasing and surge.
The manufacturer has set a reasonable carrier frequency when the inverter is in
factory. In general, users do not need to change the parameter.
