Event name Actual Position Overflow Event code 64540000 hex
Meaning The number of pulses for the actual position overflowed.
Source Motion Control Function Module Source details Axis Detection
timing Continuously
Error attributes Level Observation Recovery --- Log category System
Effects User program Continues. Operation The position is not updated, but motion continues.
System-defined
variables Variable Data type Name
_MC_AX[*].Obsr.Active BOOL Axis Observation Occurrence
Cause and
correction Assumed cause Correction Prevention
The actual position when converted to
pulses exceeded the upper limit of
signed 40-bit data. Correct the program so that the target
position is well within the pulse num-
ber limit so that the actual position
does not exceed the pulse number
limit for the instruction. Or, change the
electronic gear ratio settings. To
recover from the overflow, change the
current position or perform the hom-
ing operation. Check the gear ratio setting and the
target position setting value, and
make sure that the converted number
of pulses does not exceed the range
of signed 40-bit data. Allow some lee-
way.
