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.
