Operation
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:
Actual acceleration (deceleration time) =
Servomotor speed
Max. No. rotations
(See note.)
Speed command
Actual acceleration time
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.))
4-5-12 Electronic Gear Function (Position)
H 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.

Parameter
name
Set the pulse rate for the command pulse and
Servomotor travel distance. When G1/G2 = 1, if
the pulse (encoder resolution x 4) is input, the p
Servomotor will rotate once (i.e., the internal driver S
will rotate x 4). (See note 1.)
