• During positioning, an overrun occurs
because the deceleration distance for the
output speed is not attained at the point
where the final positioning address is
detected.
• An attempt was made to control an axis
already being moved by the manual pulse
generator by setting the manual pulse
!
generator operation enable flag for that axis.
• The speed switching point address is more
than the end point address.
• An address to control positioning in the
opposite direction was set during speed
switching control.
• The same servo program was been
executed a second time.
• In position follow-up control, when the
control unit is "degrees", a command
address outside the 0 to 35999999 has
!
been set.
• The command address has exceeded the
stroke limit range in position follow-up
control.
• In constant speed control, the speed at the
pass point exceeds the speed limit value.

Error
Corrective Action
• Set a speed at which overrun does not
occur.
• Set a travel value which will not cause an
overrun.
• Perform the manual pulse generator
operation after the axis has stopped.
• Set the speed switching point within the
range from the previous speed switching
point address to the end point address.
• Modify the sequence program.
• When the control unit is "degrees", set a
command address within the range 0 to
35999999.
• Set an address within the stroke limit
range.
• Set a speed command value between 1
and the velocity limit value.
