Operating mode settings
By changing external contact signal inputs, a max. of 15 preset speeds can be selected. (Refer to
C r-. 5 fc I f h * I for terminal allocation.)
Each speed (frequency) can be set between 0 and 400Hz.
* Note that the preset speeds cannot be set higher than the value of the max frequency | F H | • so the value
of
FH I must also be changed if a higher preset speed is desired.
Basic setting method
1, Select the desired No. of speeds for preset speed operation. S r . n ■ 0 : disabled
/~ iS : Speeds 1 to 15
2 . Select the operating mode. I 5^ /-j

Both reverse run and Acc/Dec #2 will be in effect when 3 is selected.
3. Set the operating frequencies for the applicable speeds between the lower limit and upper limit frequencies.
