NJ-series CPU Unit Motion Control User’s Manual (W507)
Event name Command Position Overflow Event code 64520000 hex
Meaning The number of pulses for the command 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
In Linear Mode, the command posi-
tion when converted to pulses
exceeded the upper limit of signed
40-bit data. Correct the program so that the input
value for the command position does
not exceed the range for the number
of pulses for the instruction. Or,
change the electronic gear ratio set-
tings. To recover from the overflow,
change the current position or per-
form the homing 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.

In Linear Mode, the command posi-

exceeded the lower limit of signed 40-
bit data. Correct the program so that the input
value for the command position does
not exceed the pulse number limit for
the instruction. Or, change the elec-

from the underflow, change the cur-
rent position or perform the homing
operation. Check the gear ratio setting and the

make sure that the converted number
of pulses does not exceed the range
of signed 40-bit data.
