Func. Name/
Code Description
B096 Dynamic braking activation level
B098 Thermistor for thermal
protection control
B099 Thermal protection level setting
Thermistor resistance threshold at which trip occurs
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
"Dynamic Braking" on page 5–6
NOTE: When cooling fan control is enabled (B092=01) the inverter always turns the fan ON
for five 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.
Free-setting
The free-setting V/f inverter mode of operation uses voltage and frequency parameter pairs to
V/f Pattern define seven points on a V/f graph. This provides a way to define a multi-segment V/f curve
that best suits your application.
The frequency settings do require that F1 ≤ F2 ≤ F3 ≤ F4 ≤ F5 ≤ F6 ≤ F7; their values must have
this ascending order relationship. To satisfy this criterion during initial parameter editing, set
F7 (B112) and work backwards when setting these values, since the defaults are all 0 Hz.
However, the voltages V1 to V7 may either increase or decrease from one to the next. There-
fore, you may set these parameters in any order.
