6.2 Motion Command Details
6.2.11 Change Filter Time Constant (SCC)
6-58
6.2.11 Change Filter Time Constant (SCC)
The SCC command transfers the setting of the Filter Time Constant (motion setting parameter OW3A) to the Mov-
ing Average Time or Exponential Acceleration/Deceleration Time Constant in the SERVOPACK and enables the set-
ting.
 Always execute the CHG_FILTER command before executing the SCC command. The setting of the servo parame-
ter to be transferred will depend on the set filter type.
 MECHATROLINK-II has a function that automatically updates setting parameters if a parameter changes. There is
no need to execute the SCC command with this function. For details, refer to bit A (User Constants Self-writing
Function) in 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 12 to execute the SCC motion command.
The parameter to which the value of OW3A is transferred will depend on the set filter type:
Without filter or with moving average filter: Moving Average Time
With exponential acceleration/deceleration filter: Exponential Acceleration/Deceleration Time Constant
IW08 will be 12 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
