Automatic angle advance function
The automatic angle advance function performs the output ON/OFF operation in advance by an
arbitrary angle (angle advance quantity) in accordance with the rotation speed of the resolver.
By using this function, delay in the mechanical operation generated during rotation at high speed
can be compensated.
The setting of this function becomes the common set point for the on angle and the off angle
outputs Y00 to Y07 and Y10 to Y17.
The response speed can be used by 830 r/min (1 degree mode), 415 r/min (0.5 degrees mode).

The automatic angle advance function can be set in 7 steps from S0 to S6 as shown in the figure
above. Enter the rotation speed (a to g) and the angle advance quantity (A to G) for each step
from the data setting panel or the PLC main unit.
The smallest rotation speed should be set in S0 with the settings increasing in sequential order of
speed. (S0<S1<S2< . . . <S6)
When the automatic angle advance function is used, the rotation speed should be 400 r/min or
less and the angle advance quantity should be 180 degrees or less.
When the rotation speed is 0 (initial value), the angle advance quantity is treated as 0.
Whether or not the automatic angle advance function is used can be set from the data operation
panel and the PLC main unit.
For the input procedure from the data setting panel, refer to Paragraph 8.3.5.
For the input destination from the main unit, refer to Paragraphs 7.1 and 7.2.
(Data is written to BFM #0 and BFM #13 to BFM #26 by a TO instruction.)
