CW Limit flag
CCW Limit flag
These bits turn ON while the respective external signals are being input.
STOP flag
This bit goes ON when positioning, ORIGIN SEARCH, ORIGIN RETURN, or JOG stop in
response to either an external interrupt signal or the STOP command bit (IR n, bit 15). It
goes OFF when any of the above operations is started. Busy flag goes ON 1 scan later.
Error code
Only the most recent error code is output. Further codes can be accessed in order by ex-
ecuting READ ERROR (IR n, bit 05). Read-out does not erase error codes.
Positioning action number
These bits output a positioning action number during positioning. Upon completion of posi-
tioning, they output the next positioning action number to be executed. The positioning ac-
tion number is automatically incremented except in cases where STOP has been executed
during positioning. In such cases, the number which was being executed at the time is taken
as the next number to be executed. After the bank has been completed, or after positioning
action #19 has been executed, the initial positioning action set in DM word m is used.
Driver completed signal
This bit turns ON during input of the servomotor driver’s driver completed signal (connected
to A9 and B9). It is used to check external wiring.
Output code
These bits output the output code for the completed positioning action. Use this data (0 to F)
as a bit in a program as follows:

Normally ON
Emergency stop signal
External interrupt signal
Origin signal
Origin proximity signal
Each of these bits turns ON when its respective signal is input. These bits are used for sys-
tem debugging. Confirm wiring by reading these bits on the Programming Console while
pressing switches by hand or using JOG to pass over switches. The bits turn ON at the trail-
ing edge when the signal is input through an NC contact, and at the leading edge when input
through an NO contact. Do not use use during programming.
Present position
The present position is always output as an absolute value (i.e., not as an increment)
through these words. After powering up, output is as follows:
