Position Detection and Positioning
The actual position H455 is calculated according to the following block diagram:
476895243
P941 = Actual position source
P961 = Modulo numerator
P962 = Modulo denominator
P963 = Modulo encoder resolution
H509 = Current actual position, absolute encoder
H510 = Current actual position, external encoder
H511 = Current actual position, motor encoder
H453 = Modulo control
H455 = Actual modulo position, output
H456 = Modulo numerator

INFORMATION
If the drive is to be positioned to the target position in the modulo range, the drive start
positioning when the target position is written to variable H454 MOD.TAGPOS. GO
commands refer to the IPOS
plus®
encoder and cannot be used for modulo positioning.
INFORMATION
The following examples use the modulo value 360°. It is also possible to scale to a
different physical value other than a modulo value.
