Insufficient remaining
distance
• At a continuous operation interrupt
request, the distance required
deceleration stop is not long enough.
• At a speed change request, the
remaining distance is shorter than the
distance required for speed change.
• When a command speed is changed:
Change to a value as near a new
speed value as possible.
• When a target position is changed:
Adjust the speed to a value as near the
command speed as possible, and then
change to a target position.
(When the operation pattern is a
continuous path control, ignore the
operations stated above.)
511 Step not possible
Code 1 is set for the step start information
when the step is outside standby.
The step will not start.
512
Illegal external
command function
The detailed parameter 2 "External
command function selection" setting range
is exceeded.
Even if the external command signal is
turned ON, the system will not perform
anything.
513
Insufficient movement
amount
The movement amount is not large
enough for automatic deceleration.
The system stops immediately after it
reaches the positioning address.
514
Outside command
speed range
• The speed change value is outside the
setting range when changing the speed
during operation.
(Note-1)
• "[Cd.140] Command speed at speed
control mode" is outside the setting
range during the speed control mode.
• "[Cd.146] Speed limit value at torque
control mode" is outside the setting
range during the torque control mode.
(Note-1): The speed change by position-
speed switching control or target
position change function is
contained.
• The speed change value is controlled as
the "maximum value within the setting
range".
• The "[Md.39] In speed limit flag" is turned
ON.
516
Illegal teaching data
