Linear Deceleration Time
7-56
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 SERVOPACKs, this command cannot be used because these
SERVOPACKs does not have the parameters for setting the deceleration time constant.
MECHATROLINK-II has a function that automatically updates setting parameters if a parameter
changes. There is no need to execute the DCC command with this function. For details, refer to bit
A (User Constants Self-writing Function) in the 6.4.1 ( 2 ) Function Selection 1 on page 6-18.

Set OW 08 to 11 to execute the DCC motion command.
The DCC command will transfer the setting of the Linear Deceleration Time (motion setting
parameter OL 38) to the Second-step Linear Deceleration Time Constant in the SERVO-
PACK and enables the setting.
IW 08 will be 11 during command execution.
IB 090 will turn ON during the command processing and will turn OFF when the process-
ing has been completed.
