8.11 Change Linear Deceleration Time Constant (DCC)
The DCC command transfers the setting of the Linear Deceleration Time (motion setting parameter OL
38) to
the Second-step Linear Deceleration Time Constant in the SERVOPACK and enables the setting.
For the SGD-
N and SGDB-
AN SERVOPACKs, this command is ignored.
