t motor function can now be set in a differentiated manner. Up to four curves with three
different triggering times can be set. The trigger times are based on classes 5, 10 and 20 for
semiconductor switching devices.
All curves run from 0Hz to half of the nominal motor frequency (P201). The full nominal current
is available from half of the nominal frequency upwards.

NOTE:
For switch-off classes 10 and 20, care must be taken that the FI has a sufficiently
high overload capacity.

P536 Current limit

0.1 ... 2.0 / 2.1
(x nominal FI
current)
[ 1.5 ]
The inverter output current is limited to the set value. If this limit value is reached, the inverter
reduces the actual output frequency.
With the analog input function in P400 = 12/13, this limit value can also be varied and cause an
error message (E12.4).
0.1 ... 2.0 = Multiplier
with the inverter nominal current, gives the limit value
2.1 = OFF,
means that this limit value is disabled. The FI supplies the maximum possible
current.
