(c) Precautions for restart at servo OFF to ON
1) To restart operation by servo OFF to ON, the difference between the
last command position and current value is output once at servo ON.
If the setting for the restart allowable range when servo OFF to ON is
large at this time, overload occurs in the machine system such as the
servo side.
Make the setting for the restart allowable range when servo OFF to ON
within the range where the machine system is not affected by the
output provided once.

at the first time.
At the servo OFF to ON performed at the second time or later, "
Setting for the restart allowable range when servo OFF to ON" is
ignored.
3) Perform servo OFF in the status where the machine system has
stopped completely.
A restart at servo OFF to ON is not applicable to the system where the
machine system is operated by external pressure, etc. during servo
