Overflow and rev. counter from
correction/storage element
Set overflow counter
To value specified in U813.03
for linear axis, always zero
for rotary axis
KK100: Absolute position of motor encoder
P595: Clockwise/counterclockwise
P183.01: Inverting of counting direction for position detection
P171: Resolution of position actual value
P180: AVWF as numerator/denominator
P169/P170: AVWF as integer places, decimal places
P146: Zero point offset
P149: Configuration protocol
P148.02: Max. countable revs. absolute encoder
U813: Configuration of position tracking, motor encoder
Index 1 (0): 0 = Rotary axis,1 = linear axis
Index 2 (15): Number of overflow incidents at linear axis (max. 15)
Index 3 (0): Setting value overflow counter, 0 ... 15
(only for linear axis)
EnDat encoder
P149.02 - P148.02: Singleturn resolution of the EnDat protocol
SSI encoder
P148.01: Singleturn resolution of the SSI protocol
P148.07: Ratio of singleturn resolution to number of pulses per
revolution
For linear encoder (P149.01 = 1xxx ):
P144/P136: Number of pulses per revolution
P148.05: Normalization ratio
<1> Refers to mechanical gear ratio, i.e. load
revolutions / motor revolutions.
This gear ratio must likewise be taken into account in the
AVWF factor.

NOTE:
Encoder overflows are only taken
into account when calculating the
start value if the position tracking
block and the storage element
have been inserted in one time
slot.
