10.2.2 Protections
The parameter P1.4 Motor nominal current acts as the ‘set point’ for the overload protection, together with oth-
er parameters in P3.9.
The parameter P1.7 Motor current limit determines the maximum current supplied to the motor from the fre-
quency converter and is set by default to the rating of the Fan Inverter.
The parameter P3.9.11 MotorStall flt protects the motor in case the fan impeller is locked or the motor has not
reached the ‘Frequency limit’ within the ‘Stall time limit’ and still current higher than ‘Stall current’.
Additional protection can be utilized by PTC thermistor in the motor and the accessory STO and ATEX(PTC)
board OPTBJ.
