Cause and
correction
Assumed cause Correction Prevention
A command that exceeded the
maximum velocity (500 kpps) was
output continuously, so the follow-
ing error for the actual output,
which is restricted by the maxi-
mum velocity, has increased. Correct the program or correct the
electronic gear ratio in the Motion
Control Function Module so that
the maximum velocity (500 kpps)
is not exceeded. Set the program or correct the
electronic gear ratio in the Motion
Control Function Module so that
the maximum velocity (500 kpps)
is not exceeded.
A command velocity that does not
correspond to the command posi-
tion was specified when a veloc-
ity-continuous pulse output was
used, so the number of pulses that
were actually output for the
updated command position has
increased.
If the Motion Control Function
Module is used, this cause does
not occur because the command
velocity is calculated automati-
cally. Correct the program so that the
command velocity corresponds to
a command position. Write the program so that the
command velocity corresponds to
a command position. Or, use the
Motion Control Function Module.
