This function advances the ON/OFF timing from the preset angle in
propor tion to the rotational speed of the machine (encoder). It
automatically compensates for the delay in output timing during high-
speed operation, eliminating the need to switch the program according
to the operation speed that is a characteristic of conventional systems.
Refer to "4.2 Advance Angle Compensation (ADV) Function".
Example When 2° is set to the angle advancement for a rotational
speed of 100 r/min

In high-speed operation
(500r/min)
The bank function allows registration of up to eight types of programs.
You can switch among them simply by selecting a desired program
when changing a setup or the targeted type of a workpiece.
The bank function also simplifies programming since it offers a
program copy function.
Refer to "4.8 Bank Function (F7/F8/F9)".

It is possible to set upper and lower limit values for the rotational
speed. When the actual rotational speed exceeds the upper-limit
value or falls below the lower-limit value, the corresponding alarm is
output.
Refer to "4.5 Speed Alarm (F3/F4)".
