YASKAWA SVC - SCC (Change Filter Time Constant)

4.2 Motion Command Details
4.2.11 SCC (Change Filter Time Constant)
4-66
4.2.11 SCC (Change Filter Time Constant)
The SCC command transfers the set value of the OW3A setting parameter (Filter Time
Constant) to the Moving Average Time or Exponential Acceleration/Deceleration Time Constant
SERVOPACK parameter and enables the setting.
Execution and Operating Procedures
1. Make sure that all of the following conditions are met.
* Before you change to this command during the execution of another command, you must check whether
the command can be changed and how operation changes when the command is changed. Refer to the
following section for details on changing from another command.
4.4 Changing the Command on page 4-137
2. Set the OW08 setting parameter (Motion Commands) to 12 to execute the SCC
motion command.
The SERVOPACK parameter to which the value of OW3A is transferred will depend on the filter
type that has been set.
No filter or moving average filter: Moving Average Time
Exponential acceleration/deceleration filter: Exponential Acceleration/Deceleration Time Constant
The IW08 monitor parameter (Motion Command Response Code) is 12 during execution of this
command.
During command processing, bit 0 (Command Execution Flag) in the IW09 monitor parameter
will change to 1 (Processing). When processing is completed, this bit will change to 0 (Completed).
3. Set OW08 to 0 to execute the NOP motion command.
This concludes the process for changing the filter time constant.
Holding and Canceling Commands
Bit 0 (Hold Command) and bit 1 (Cancel Command) in the OW09 setting parameter can-
not be used to stop the axis.
Related Parameters
The parameters that are related to this command are listed in the following table.
 Setting Parameters
An SVC Function Module can automatically transfer setting parameters to SERVOPACK parame-
ters when they are overwritten. The SCC command is not required if this function is used. Refer
to the following section for details.
