Command Reference
8.1.5 S-curve Time Constant Change (SCC)
(1) Overview
The S-curve Time Constant Change command (SCC) changes the S-curve time constant of each axis for which
an axis move command is executed.
The S-curve time constant is the parameter for the S-curve acceleration/deceleration function that suppresses
mechanical vibration during acceleration/deceleration.
The S-curve time constant for up to 16 axes can be changed at once. The S-curve time constant of any axis
unspecified in the command block is not changed.
The S-curve time constant changed by the SCC command remains until it is reset by the next SCC command.

All motion modules, except the PO-01 module, support ACC, DCC, and SCC commands.
Use of these commands with PO-01 module requires the following combination of Machine Controller and PO-01 module
version numbers.
