Position Comparison Output Function
Operation
•
A time width pulse set in Pr4.44 “Position comparison output pulse width setting”
will be output, when the actual position of the encoder passes over the position
comparison value (Pr4.48 to Pr4.55),
・ Regardless of the direction of encoder position travel, a pulse will be output when
the magnitude correlation changes as it passes over the position comparison value.
・ Multiple position comparison value can be set to one position comparison output.
・ When the operation direction has been reversed, or when the external scale position has
passed the position comparison value, a state where pulse output is ON will continue
from the time of the most recent passing until the output pulse width set value is reached.
•
When stopped at the same position as the position comparison value, a single pulse will
be output, similar to the case of passing over.
・
The position comparison output function sends outputs while automatically compensating,
based on the previous motor speed, the errors caused by the time of delay of encoder serial
communication, etc. In addition, the amount of correction can also be adjusted with the
setup of the amount of position comparison output delay correction (Pr4.56).
