of errors
Error
code
Error name Error Operation status at error occurrence
514
Outside new current
value range
The new current address is outside the
ranges of 0 to 359.99999, where the
control unit is set to "degree".
515
New current value not
possible
• The control system sets an operation
pattern (continuous path control) using
new current positioning data.
• The operation pattern sets a "new current
value" in the control system using the
data following the "continuous path
control" positioning data.
Current value is not changed.
516
Continuous path
control not possible
• The continuous path control is designated
using a control system which is not
allowed to use for continuous path control
such as speed control, speed-position
switching control, position-speed
switching control, fixed-feed, and current
value changing.
• The previous data such as those on
speed control, speed-position switching
control, position-speed switching control,
fixed-feed, and current value changing
shows a continuous path control.
• The continuous positioning control is
designated for speed control or position-
speed switching control.
The system does not operate at start.
518
Outside operation
pattern range
The operation pattern set value is 2.
519
Interpolation while
interpolation axis BUSY Interpolation is started during the operation
of the interpolation axis.
520 Unit group unmatched
The reference and interpolation axis units
are different at the parameter "interpolation
speed designation method" setting of
"composite speed".
521
Illegal interpolation
description command
In 2-axis interpolation, the axis to be
interpolated is the self axis or an axis not
present.

522
Command speed
setting error
The command speed is outside the setting
range.
Linear interpolation, circular interpolation:
Reference axis is outside the setting
range.
Speed control interpolation:
Either of reference axis and interpolation
axis is outside the speed range.
At start : The system does not
operate.
During operation : The system stops with the
setting (deceleration
stop/sudden stop) of the
detailed parameter 2
Sudden stop selection
(stop group 3).
(Note that the deceleration
stop only occurs during the
manual pulse generator
operation.)
