Current address change function

With this function, the current address of a stopped axis changes arbitrarily.
Write the desired value to the current address (user) to change, followed by the current address (pulse)
update.
Note
The current address does not change in the following states.
• READY/BUSY in the status information is OFF (0).
• Interruption due to a STOP command occurs and the operation is waiting for the remaining distance.

1(ON): Enable
BFM #14202 Disables the START command without zero return
b2 completion. Enables the START command with zero
return completion (zero return completed: ON)
0(OFF): Disable
Turns ON upon completion of mechanical zero return operation, or
when the current position is established by the absolute position
detection system.
BFM #128 b3
Turns OFF at OFF-to-ON transition of a mechanical zero return
command, at power-off (reset), or when an absolute position is
lost during the absolute position detection system.
