05 - Multi-Speed Parameters
Code Parameter Name / Range
05-00 Acceleration and deceleration selection of multi-speed
0: Acceleration and deceleration time 1 ~ 4 used.
1: Use independent acceleration and deceleration time for each multi-speed setting.
05-00=0: Standard Acceleration and deceleration times parameters 00-14 ~ 00-17 / 00-21 ~ 00-24 are used for
multi-speed 0 ~ 15.
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
Time it takes to reach set frequency =
Acceleration time x (set frequency - output frequency)
Maximum output frequency
Deceleration time calculation formula
Time it takes to reach set frequency =
Deceleration time x (output frequency - set frequency)
Maximum output frequency
Maximum output frequency: Parameter 01-00=F, maximum output frequency set by 01-02, 01-00 ≠ F, maxi-
mum 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 (Accel-
eration time), 05-18=20.0 sec. (Deceleration time).
Acceleration time calculation formula
Time it takes to reach set frequency =
5.0 x 10 Hz
= 1.0 sec.
50 Hz
Deceleration time calculation formula
Time it takes to reach set frequency =
20.0 x 10 Hz
= 4.0 sec.
50 Hz
Example: Acceleration / deceleration timing when 05-00 is set to 1. In this example the following parameters
are set:
00-02=1 (External Terminal Operation)
03-00=0 (Terminal S1: Forward /Stop)
03-01=1 (Terminal S2: Reversal /Stop)
03-02=2 (Terminal S3: Speed 1)
03-03=3 (Terminal S4: Speed 2)
03-03=4 (Terminal S5: Speed 3)
*Speed 1 is required to conrm if AI2 function setting (04-05) is set to 0 (Auxiliary frequency). If 04-05=0, it will
make the frequency of speed 1 set to AI2 auxiliary frequency and the value is determined by AI2. If function of
speed 1 is generally used, set AI2 to other functions except 0 (the recommended value: set 10 ADD to AI1.)
