DC Bus AVR for deceleration Settings
This function is to achieve stable DC bus voltage in case of deceleration. DC bus voltage
raises due to regeneration during deceleration. When this function is activated
(B133=01), inverter controls the deceleration time so that the DC bus voltage not to go
up to the overvoltage trip level, and leads to the tripless operation during deceleration.
Please note that the actual deceleration time may be longer in this case.
