5% or not ; check encoder cable
and shielded line if it is damaged or not;
check encoder cable whether it is
intertwined with other power wire or not
Ensure power voltage of encoder
normally, ensure encoder cable and
shielded line well with FG ground,
ensure encoder cable separated with
other power wire

Content:positionerrorover‐largeerror
Cause Confirmation Solution
Unreasonable set of
position error parameter
Check parameter PA_014 value if it is too
small or not
Enlarge the value of PA_014
Gain set is too small
Check parameter PA_100, PA_105 value
if it is too small or not
Enlarge the value of PA_100,
PA_105
Torque limit is too small
Check parameter PA_013, PA_522 value
whether too small or not
Enlarge the value of PA_103,
PA_522
Outside load is too large
Check acceleration/ deceleration time if it
is too small or not , check motor rotational
speed if it is too big or not ; check load if
it is too large or not
Increase acceleration/
deceleration time decrease
speed, decrease load

Content:velocityerrorover ‐largeerror
Cause Confirmation Solution
The deviation of inner position
command velocity is too large
with actual speed
Check the value of PA_602 if
it is too small or not
Enlarge the value of PA_602, or set the
value to 0, make position deviation
over-large detection invalid
The acceleration/ decelerate
time Inner position command
velocity is too small
Check the value of PA_312,
PA_313 if it is too small or not
Enlarge the value of PA_312, PA_313.
adjust gain of velocity control, improve
trace performance.
