(1) in case of A089 = 0 :
The standard of acceleration time and deceleration time is set by maximum frequency(F003)
standard. That is, if the acceleration time(F007) which reaches to maximum frequency(F003)
60Hz is set to 30 seconds, the arrival time to 30Hz becomes 15 seconds.

(2) in case of A089 = 1 :
The arrival time to setting value of output frequency is accelerating time regardless of
maximum frequency.
That is, if output frequency(F001) is set to 30Hz when maximum frequency is 60Hz and
accelerating time is 30 seconds, the arrival time to 30Hz becomes 30 seconds.
But it is valid when the acceleration and deceleration pattern is linear.
