This is the positioning completed
input signal used in the origin search
for pulse output 0. The input signal
from the servo driver is output to this
bit from the ladder program to enable
using the signal.
The pulse output 1 PV (contained in
A278 and A279) will be cleared when
this bit is turned ON.
This is the CW limit input signal for
pulse output 1, which is used in the
origin search. To use this signal,
write the input from the actual sensor
as an input condition in the ladder
program and output the result to this
flag.
This is the CCW limit input signal for
pulse output 1, which is used in the
origin search. To use this signal,
write the input from the actual sensor
as an input condition in the ladder
program and output the result to this
flag.
This is the positioning completed
input signal used in the origin search
for pulse output 1. The input signal
from the servo driver is output to this
bit from the ladder program to enable
using the signal.
Turn ON this bit to reset the Error
Counter 0 Present Value and turn
OFF the Error Counter 0 Error Flag.
Turn ON this bit to hold the present
value of error counter 0.
Turn ON this bit to reset the Error
Counter 1 Present Value and turn
OFF the Error Counter 0 Error Flag.
Turn ON this bit to hold the present
value of error counter 1.
Automatically stores the number of
retries in the FB communications
instruction settings specified in the
PLC Setup.
Automatically stores the FB commu-
