Load / Save of Parameters by Synchronous Action
By using the synchronous action, the user can load the value pre-set in a multi-purpose register as a new speed or drive pulse
number, and save the current position and a speed to a multi-purpose register.

Fig. 2.4-3 Usage Example of Saving Parameters
There are 7 kinds of parameters that are loadable from the multi-purpose register by using the synchronous action and 5 kinds of
parameters that can be saved in the multi-purpose register. Load / save of parameters will be executed to the multi-purpose register
according to the synchronous action SYNC3~0 activation.
To load /save the parameters by using the synchronous action, the user needs to set the action code for the action of the
synchronous action set which the user wants to use by executing synchronous action SYNC3~0 setting command
(26h,27h,28h,29h). And the synchronous action set which the user wants to use must also be enabled by synchronous action
enable setting command (81h
～
8Fh).
