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.
