6. Explanation of F-Group Function
49
(1) In use O-L, OI-L case
When frequency command is control terminal (Terminal), by setting lower limit, even if
0V(4mA) is input, it is not possible to output less than the frequency set with lower limit.
Fig. 6- 5 Frequency limit curve (In use O-L, OI-L case)
(2) In use O2-L case
When using the lower frequency limit and 0V is inputted into O2 terminal, F006 applies to both
forward and reverse directions.
(a) When operation command is control terminal
(b) When operation command is operator
(F011=1) (F011=2)
Note) When using the external frequency control, refer to the table 9-12 about external analog input
signal (AT terminal selection (I049) and O2 terminal selection(I038)).
6.6
Adjustable time setting (F007/F207, F008/F208)
(1) The acceleration and deceleration time can be set.
Set a long time to accelerate or decelerate slowly or set a short time to accelerate or
decelerate quickly.
(2) The time setting is the time it takes to accelerate from 0Hz to the maximum frequency(F003)
and to decelerate from the maximum frequency to 0Hz.
