4-138
05-00=0:
Standard Acceleration and deceleration times parameters 00-14 ~ 00-17 apply to all preset speeds.
05-00=1:
Each multi-speed uses a dedicated acceleration and deceleration time parameters 05-17 ~ 05-48.
There are two different modes for acceleration / deceleration timing when 05-00 is set to 1, see time example on
the next page.
Acceleration time calculation formula
Acceleration time x (set frequency - output frequency)
Time it takes to reach set frequency =
Maximum output frequency
Deceleration time calculation formula
Deceleration time x (output frequency - set frequency)
Time it takes to reach set frequency =
Maximum output frequency
Maximum output frequency:
Parameter 01-00=18, maximum output frequency set by 01-02, 01-
00 ≠ 18,
maximum output frequency determined by V/F curve selected (50.0 / 60.0 / 90.0 / 120.0 / 180.0).
Example:
01-00=01 (50Hz (maximum output frequency), 05-02=10 Hz (multi-step speed 0),
05-17=5.0s
(Acceleration time), 05-18=20.0 sec. (Deceleration time).
Acceleration time calculation formula
5.0 x 10 Hz
Time it takes to reach set frequency =
= 1.0 sec.
50 Hz
Deceleration time calculation formula
20.0 x 10 Hz
Time it takes to reach set frequency =
= 4.0 sec.
50 Hz
