8.8 Overvoltage stall suppression
During the operation of the inverter, if the bus voltage exceeds the overvoltage stall protection voltage
FE.06, the overvoltage stall will take effect, adjust the output frequency, and the actual deceleration time will
be automatically lengthened to avoid trip protection.

The start protection of the inverter can be protected by parameter F8.31 startup protection : if the running
command is valid when the inverter is powered on (for example, the terminal running command is in the closed
state before power-on), the inverter will not respond to the running command, and must be turned off first. The
