Error cause
• When the skip is executed in the
constant-speed control, the next
interpolation instruction is an
absolute circular interpolation or
absolute helical interpolation.
• The current value was changed
during positioning control of the
applicable axis.
• The current value was changed for
the axis that had not been started.
• The current value was changed for
the servo OFF axis.
• The speed was changed for the axis
during circular interpolation.
• The speed was changed after

start.
• The speed was changed during
deceleration by turning off the JOG
start command signal
(M4802+20n, M4803+20n).
• The speed after speed change is
set outside the range of 0 to speed
limit value.
• The absolute value of speed after
speed change is set outside the
range of 0 to speed limit value.
• The current value was changed
outside the range of 0 to 35999999
