 Operation with immediate value data
When immediate value data are directly set by the RS-485 communications, if the start positioning
signal is set, positioning is started according to the setting.
This operation differs from the operation with positioning data in the continuation function and
setup of the stand still timer.
For the continuation function, a similar function can be realized by assigning the immediate value
continuation to the CONT signal.
In addition, if you wish to change data immediately during operation, the function of the immediate
value change is usable.
For the function of the stand still timer, adjust timing using the host controller.

 Stop method
The servo motor is decelerated before the specified position set by positioning data, and stopped
automatically at that position.
The method for stopping the motor forcibly after moving has started is as follows:

Turn off the operation command [RUN].

Turn off the forced stop [EMG].

Turn on the positioning cancel.

Turn off the external error input.

Turn on the pause (By turning it off, the remaining operation is executed).

Turn on free run.
After the motor has started moving, if one of the signals below is detected, the specified position of
positioning data might not be reached.

Software OT (overtravel), +OT, and -OT signals

Limiter detection
