(4) Precautions during software stroke limit check
• A machine OPR must be executed beforehand for the "software stroke limit function" to function properly.
• During interpolation control, a stroke limit check is carried out for the every current value of both the
reference axis and the interpolation axis. Every axis will not start if an error occurs, even if it only occurs in
one axis.
• During circular interpolation control, the "[Pr.12] Software stroke limit upper limit value"/"[Pr.13] Software
stroke limit lower limit value" may be exceeded. In this case, a deceleration stop will not be carried out even
if the stroke limit is exceeded. Always install an external limit switch if there is a possibility the stroke limit will
be exceeded.

Starting address
The software stroke limit check is carried out for the following addresses
during circular interpolation control. (Note that " Da. 7 Arc address" is carried
out only for circular interpolation control with sub point designation.
Current value/end point address ( Da. 6 )/arc address ( Da. 7 )
Deceleration stop not carried out
