4.2 Advance Angle Compensation (ADV) Function
4.2.1 What Is the Advance Angle Compensation (ADV) Function?
The ADV function advances the ON/OFF timing relative to the preset
value and proportional to the Encoder rotation 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.
■ General Concept of the ADV Function
The ADV value (point A) is set for a particular speed (2° at 100 r/min in
this example), ADV value is used to linearly compensate outputs
according to the speed based on an ADV value set for a specific
speed.
