6.2 Motion Command Details
6.2.10 Change Deceleration Time (DCC)
6-56
6.2.10 Change Deceleration Time (DCC)
The DCC command transfers the setting of the Straight Line Deceleration Time Constant (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-N SERVOPACKs, this command cannot be used because these SERVO-
PACKs 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 4.4.1 ( 2 ) Function Selection 1.
( 1 ) Executing/Operating Procedure
1. Check to see if all the following conditions are satisfied.
2. Set OW08 to 11 to execute the DCC motion command.
The DCC command will transfer the setting of the Straight Line Deceleration Time Constant (motion setting
parameter OL38) to the Second-step Linear Deceleration Time Constant in the SERVOPACK and enables
the setting.
IW08 will be 11 during command execution.
IW09, bit 0 will turn ON during the command processing and will turn OFF when the processing has been
completed.
3. Set OW08 to 0 to execute the NOP motion command and then complete the change of the linear
deceleration time constant.
( 2 ) Holding and Aborting
The Holds a Command bit (OW09, bit 0) and the Interrupt a Command bit (OW09, bit 1) cannot be used.
( 3 ) Related Parameters
[ a ] Setting Parameters
No. Execution Conditions Confirmation Method
1 There are no alarms. Both IL02 and IL04 are 0.
2 Pulse distribution has been completed for the SERVOPACK. IW0C, bit 0 is ON.
3 Motion command execution has been completed. IW08 is 0 and IW09, bit 0 is OFF.
Parameter Name Setting
