(1) Type 1 (code method)
Using an external signal, override can be applied to the commanded rotation speed of a spindle or mill spindle in 10%
increments from 50% to 120%.
(2) Type 2 (value setting method)
Using an external signal, override can be applied to the commanded rotation speed of a spindle or mill spindle in 1%
increments from 0% to 200%.
(Note 1) Selection between type 1 and type 2 can be designated by PLC program processing.
