4.2 Motion Command Details
4.2.13 KVS (Change Speed Loop Gain)
4-70
4.2.13
KVS (Change Speed Loop Gain)
The KVS command transfers the set value of the OW
2F setting parameter (Speed Loop
Gain) to the Speed Loop Gain 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 14 to execute the KVS
motion command.
The value of OW
2F is transferred to the Speed Loop Gain SERVOPACK parameter and is
enabled.
The IW
08 monitor parameter (Motion Command Response Code) is 14 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 speed loop gain.
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 KVS command is not required if this function is used. Refer to
the following section for details.
