B090: Dynamic braking usage ratio – This parameter limits the amount of time the inverter
can use the dynamic braking accessory device without entering the Trip Mode. Please refer to
for more information on dynamic braking accessories.
NOTE: When cooling fan control is enabled (B092=01) the inverter always turns the fan ON
for 5 minutes immediately after powerup. This will cool the inverter in case the inverter / motor
is still warm from prior running before a short power outage.
