(Note-1): A speed change is valid only at the execution of travel mode in the PTP or constant speed.
(Note-2): This mode is executed by G00, G28, G30 or G53. OSC mode is the travel mode executed by G25.
(Note-3): This mode is executed by G01, G2, G3, G12, G13 or G32. The independent M-code is also handled as the
constant speed mode.
(Note-4): When a special M-code (M00, M01, M02, M30, M98, M99, M100) is not executed during the constant speed
mode after speed change.
(Note-5): When a special M-code (M00, M01, M02, M30, M98, M99, M100) is executed during the constant speed mode
after speed change.
The decelerates stop is made at the execution of the special M-code.
(Note-6): PTP mode: High-speed feed rate. OSC mode: F (frequency) command. Constant speed mode: F (speed)
command.
