Function code 24
This function allows tor limiting the motor current in the starting
phase. lt the motor current is higher than the preset maximum current
the Inverter output trec~uency is held constant until the current
demand of the motor is smaller than the inverter‘s preset maximum
current value. At this point, the acceleration phase is once again
resuned.

The data code tor the maximum inverter output current, which must not
be exceeded during the starting phase, can be calculated as follows:
starting
current (%) =
maximum inverter out~ut current A ~ 100 %
nominal inverter current A
The coded input ot the starting current is achieved according to
the following table:
