Advance Angle Compensation (ADV)
Function
The advance angle compensation function automatically advances
the ON/OFF angle of cam outputs in proportion to machine
(encoder) speed. As the speed of the machine increases, the system
can be affected by the delay in outputs. If the ADV function is used,
the output delay caused by higher speeds is automatically
compensated.
As shown in the following diagram, ADV function is used to linearly
compensate outputs according to the speed based on the ADV value
setting for a specific speed.

ADV value can be set independently for cams 1 to 7 (7 total). For the
ADV function, the speed and the amount of angle compensation are
set. If “- - -” is displayed for any setting, the ADV function is disabled.
The setting ranges are given in the following table.

Note: Even if the ADV value is set to 0°, the cam must be included in
the number of cams with ADV settings.
Example: Setting the ADV Value to 2 ° at 100 r/min for Cam 4
1. Set the mode switch to PRGM or TEST.
2. Set cam number 4 with the CAM Keys
