• Sets the command pulse soft start. The soft start property is the primary filter (exponentiation func-
tion).
Note 1. The soft start properties also include linear acceleration and deceleration. (Set the time con-
stant using Pn208.) Select the filter you want to use using Pn207.0 (position command filter
selection).
Note 2. Refer to 4-5-13 Position Command Filter Function for details.

• Sets the amount of multi-turn rotation when using a Servomotor with an absolute encoder.
• If using an absolute encoder, the counter counts the number of rotations from the setup position, and
outputs the number of rotations from the Servo Driver (When SEN signal is input, output from CN1-48:
+ absolute, or CN1-49 – absolute).
• With the default setting (Pn205 = 65535), the Servomotor multi-turn data will be as follows:
Multi-turn data
Forward
Reverse
Servomotor rotations
• With the default settings changed (i.e., Pn205 65535), the Servomotor multi-turn data will be as
follows:
Rotation data
Forward
Reverse
Servomotor rotations
Pn205 set value
That is, when the default settings are changed (i.e., Pn205 65535), the Servomotor multi-turn
data will be only in the positive direction. If you want to set the multi-turn limit as high as possible,
with the entire operating area positive, set a number such as 65534.
To return the multi-turn data to 0 each time the motor (e.g., turntable) completes m rotations, set the
value (m–1) in Pn205. For example, if the machine’s gear ratio is 1/33, set 32 in Pn205 to return the
multi-turn data to 0 after 33 rotations.
Note If Pn205 is changed, the limit to the number of rotations in the encoder memory and the limit to the
number of rotations in the Servo Driver memory will no longer agree, so an A.CC alarm (multi-turn
limit nonconformity) will be generated. To cancel this alarm, the setting for the number of multi-
turns (Fn013) must be changed in the System Check Mode.
