Max. allowable output current. The
factory-set value corresponds to a 160%

on unit
load of the rated motor size.
Not applicable to all types.
Settings between 105% and 160% may
only be applied on intermittent operation.
If the set value is too low the motor will not
start.
This value sets the lower warning frequen-

If the output frequency is below f
display shows FREQ. VAR. LOW.
The signal outputs can be programmed
to give a warning signal (parameters
407-410).

The sinusoidal ramps cannot be set with
steps as small as the linear ramp, even
though the display indication appears to be
continuous.
