Figure 3.18 S-CURVE TIME CONSTANT CHANGE (SCC)
The SCC command reference range is as follows:
1 to 510 [ms]
1. When the SCC command is not executed, the S-curve time constant is determined by the S-curve Time
Constant setting parameter.
2. The S-curve time constant changed by SCC command execution remains in effect until it is reset by the
next SCC command.
Do not use the SCC command with the SVA Modules.
