(3) Setting Items for SCC Command
Motion Image
Specify a numerical value or register for the S-curve time constant of each axis using an SCC command.
The reference range of the S-curve time constant depends on the motion module to be used:
• For SVA-01, PO-01, and SVR modules, the reference range is specified by motion setting parameter
OW 3A (Filter time constant).
• For built-in SVB and SVB-01 modules, the reference range is specified by the SERVOPACK parameter
Average Movement Time.
The following table shows the reference range of S-curve time constants for each motion module model.
• If a reference value of more than 6553 ms is input, a motion program alarm will occur regardless of the motion module
model.
• If a reference value exceeds the upper limit (511 to 6553 ms) when using a built-in SVB or SVB-01 module, bit 1 of
motion monitoring parameter IL 02 is set to 1 (Set parameter error), and the upper limit (510 ms) is set for the Aver-
age Movement Time of the SERVOPACK parameter.

With the SGDJ SERVOPACK, the S-curve acceleration/deceleration can-
not be used since the SERVOPACK does not have a parameter for Aver-
age Movement Time.
