Performing Registration
This example shows how to use the /RGRT signal during execution of a program step to
change to the specified speed and perform positioning for the specified distance.
When the /RGRT signal turns ON during step 0, positioning is performed for a travel distance
(RDST) of 100,000 reference units.
The speed changes to 15,000,000 reference units/min (RSPD).
When the /RGRT signal turns ON during step 1, positioning is performed for a travel distance
(RDST) of 100,000 reference units.
The speed changes to 15,000,000 reference units/min (RSPD).
The program table for this positioning is shown below.

Operating Procedure
Turn ON the /MODE 0/1 signal to change to mode 0.
Set the /SEL0 to /SEL7 signals to 0 to specify program step 0.
Turn ON the /START-STOP signal to start program table operation.
The /INPOSITION signal turns OFF.
The /RGRT signal turns ON to perform registration operation.
The speed changes to the registration speed.
The /INPOSITION turns ON when positioning is completed for the registration distance.
When execution of program step 1 starts, the /INPOSITION signal turns OFF.

Operation Pattern and Related Signal Timing
*1.
Do not change /SEL0 to /SEL7 for 4 ms after turning ON the /START-STOP signal.
*2.
PnB12 = 0000h (Registration is started by changing the /RGRT signal from OFF (open) to ON (closed)):
20 μs min.
PnB12 = 0001h (Registration is started by changing the /RGRT signal from ON (closed) to OFF (open)):
200 μs min.
*3.
The /RGRT signal is ignored during registration operation.

If the remaining distance to the target position is shorter than the registration distance (RDST)
when the /RGRT signal turns ON, an E23A serial command not acknowledged response
(A.AEF (Insufficient Registration Distance Alarm)) occurs, the servo is turned OFF, and pro-
gram execution is stopped.
