2. Starts menu
This main menu includes the parameters related to the starting of the motor operated by the frequency converter.
Following parameters can be set here:
•
normal rise time,
•
mode of rise,
•
data of rise with breakpoint,
•
S curve,
•
start inhibition,
•
inhibition of direction change,
•
start backwards,
•
mode of start,
•
loosen of the brake,
•
flying scissor,
•
flying start
Explanation of the acceleration time
Submenu Explanation, further submenus Values Default setting Unit
2-1
rise time
It means at both control and regulation the limitation of the slope of the frequency rise.
2-1-1 control Tup
0,05 - 3276,7 5,00 s
2-1-2 regulation Tup
0,05 - 3276,7 5,00 s
2-1-3 referencing
Setting the reference of the rise and fall time.
(With fnom. selected, the rise and fall steepness
do not change with changing fmax.)
f max.
f nominal f max.
If the rise time is assigned to fmax (factory setting), the time set refers to between 0 Hz and fmax.
There is possibility for assigning the rise time also to the nominal frequency of the motor (in menu 2-1-3 ).
The effective acceleration time ( tup ) belonging to a given frequency can be calculated.
