Pr.30 UL BF Level
•
Based on
Pr.04
Setting to
Normal Duty
The under load trip levels (% of motor amps) are based on a
variable torque (quadratic) curve with the low level setting (Pr.29)
when operating at 2 x slip frequency (bA.12) and the upper level
setting (Pr.30) when operating at base frequency (dr.18).
•
Based on
Pr.04
Setting to
Heavy Duty
The under load trip level (% of motor amps) is based on a constant
torque curve when operating between 2 x slip frequency (bA.12)
and the base frequency (dr.18). The trip level setting (Pr.30) applies
throughout the speed range. Pr.29 is not used.
Fan Fault Detection
The inverter monitors the cooling fan for proper operation. When an error or fan failure
occurs, the inverter responds to the failure based on the setting of Pr.79 (cooling fan fault
selection). The inverter will display a fan fault (Fan) or warning (FanW). Eith
er Relay1 or
Relay2 (OU.31 or OU.33) can be set to 8 (Fan Warning) to provide an output signal.
