Note 1.
If not using the soft start function, set this parameter to 0 (default setting).
Note 2.
The actual acceleration and deceleration time is as follows:
x soft start acceleration (deceleration) time
Servomotor speed
Actual acceleration time
Max. No. rotations
(See note.)

Time
maximum No. rotations (r/min.)
Actual acceleration (deceleration time) =
speed command (r/min.)
Note
The maximum rotation speeds are as follows:
•
3,000-r/min. Servomotor: 5,000 r/min.
•
3,000-r/min. Flat-style Servomotor: 5,000 r/min.
•
1,000-r/min. Servomotor: 2,000 r/min.
•
6,000-r/min. Servomotor: 6,000-r/min.
•
1,500-r/min. Servomotor: 3,000-r/min. (except 11 kW and 15 kW (= 2,000-r/min.))

Functions
•
This function rotates the Servomotor for the number of pulses obtained by multiplying the command
pulses by the electronic gear ratio.
•
This function is enabled under the following conditions.
When fine-tuning the position and speed of two lines that are to be synchronous.
When using a position controller with a low command pulse frequency.
When you want to set the travel distance for machinery per pulse to 0.01 mm, for example.
