5.2.9 S5 Limit operations in traveling movement application
The functions of the slowdown limit input DI4, stop limit input DI5 and slowdown limit frequency are adjusted with
this switch group. Value of the slowdown speed is given as a percentage of the set maximum frequency (see
section “S1 Maximum driving frequency”). If slowdown frequency is set lower than the minimum frequency (switch
S2), the set value is equal to the minimum frequency.
Note: As factory default DI5 is not in use. The stop limit signal shall be connected in series to direction signals respectively.
Note: There are two possibilities to make limit circuits:
1-step limit (slow down)
1.
2-step limit (slow down and stop)
CAUTION
Wrong parameter setting may accidentally deactivate the slowdown function
as well as the slowdown and stop limits, possibly causing hazardous
situations.
