correction Assumed cause Correction Prevention
A negative limit input signal was
detected. Reset the error and move the axis
back in the positive direction before it
exceeds the limit in the negative
direction. Find the reason the limit
was exceeded and make suitable cor-
rections. The goal is to detect the negative limit
input. Preventative measures are not
required. However, be sure not to
exceed the negative limit input when
making programs.
The negative limit input signal is not
connected correctly or the logic set-
ting for the negative limit input is
wrong. If a negative limit input signal does
not occur, correct the connection of
the negative limit signal and the logic
setting for the negative limit input. Make sure that the negative limit sig-
nal connection and logic setting for
the negative limit input are correct.

Event name Illegal Following Error Event code 64560000 hex
Meaning The difference between the command position and the actual current position exceeds the range of 30-bit data when
converted to pulses.

Cause and
correction Assumed cause Correction Prevention
The command current position was
restricted so that the axis velocity of
the slave axis would not exceed the
axis maximum velocity for the speci-
fied travel distance. Correct the program or correct the
electronic gear ratio so that the slave
axis does not exceed the maximum
velocity. Write the program or set the elec-
tronic gear ratio so that the slave axis
does not exceed the maximum veloc-
ity.
Performance of slave axis positioning
operation is poor and the actual
motion is slower than the command. Remove the cause of poor slave axis
following performance in the position-
ing operation. Remove the cause of poor slave axis
following performance in the position-
ing operation as best you can.
