Operating mode settings
By changing external contact signal inputs, a max. of 15 preset speeds can be selected.(Refer to

*I
for terminal allocation.)
Each speed (frequency) can be set between O and 400Hz.
*Note that the preset speeds cannot be set higher than the value of the max frequency
IF 1-11 ,
so the
value of
IF
1-11
must also be changed if a higher preset speed is desired.
