Origin Search Operation
Section 8-2
When using W-series Servo Drives, the first-step acceleration/deceleration
curve operations require parameter settings for Pn80B and Pn80E only. When
using an exponential curve for the acceleration/deceleration curve, Pn810 and
Pn811 must be set for W-series Servo Drives.
Movement Average Time for W-
series Servo Drives (Pn812) or Moving Average Time for G-series Servo
Drives (Pn10E) must be set when using an S-curve for the acceleration/decel-
eration curve.
The second-step acceleration/deceleration constant cannot be set using a
G5-series Servo Drive or G-series Servo Drive. The exponential acceleration/
deceleration filter cannot be set because there is no exponential acceleration/
deceleration filter function.
The SMARTSTEP Junior Servo Drives do not support the following parame-
ters: Pn80A, Pn80C, Pn80D, and Pn80F. They also do not support accelera-
tion/deceleration filters, so the filters cannot be set. One-step linear
acceleration/deceleration curves are set using only Pn80B and Pn80E.
For details on acceleration/deceleration curves, refer to 7-4 Acceleration and
Deceleration Operations .
