Feedback Settings
If the EDM input (monitored input) is changed while the program is being exe-
cuted when using EDM function blocks, the EDM feedback signal will not
change and will trigger a feedback error. Use the feedback settings to link the
reverse output signal to the EDM feedback signal in the EDM function block to
avoid feedback errors.
Note
Feedback settings operate based on the Windows timer, which has error. The
error becomes larger particularly when the load on Windows is high. If this
happens, feedback error may occur even if feedback settings have been
made. To avoid feedback errors, make the cycle time base setting larger than
the current value.
Use the following procedure to set the feedback settings.
