S-Curve Time Constant Change (SCC) Command

! Outline

The S-curve Time Constant Change (SCC) command sets up the S-curve accel/decel func-
tion parameter that suppresses machine vibration during accel/decel.

! Detailed Explanation

The SCC command method is shown as follows:

According to the above command, the S-curve time constant of each axis is changed;
however, that of the undesignated axis is not changed.

• When the SCC command is not sent, the S-curve time constant is determined by the

S-curve Time Constant setting parameter.

• The S-curve time constant changed by the SCC command is valid until being reset by

the next SCC command.

• A designating range of the SCC command is as indicated below.
