Relationship between acceleration, deceleration time and output frequency
Set values of acceleration and deceleration time are the time durations to reach base frequency
from 0Hz and 0Hz from the base frequency. Therefore, real acceleration/deceleration time is
smaller than the set value when the commanding frequency is smaller than the base frequency.
[EXAMPLE]
• Base frequency: 60 Hz,
• Current output frequency: 0Hz,
• Commanding frequency: 40 Hz,
• Acceleration time: 30[Sec],
• Deceleration time: 30[Sec]
