Operation status at error occurrence

518

Outside operation
pattern range

• The operation pattern set value is 2.

• A target position change is

requested on those control
systems other than ABS1 and
INC1.

• A target position change is carried

out in continuous path control.

• A changed address is outside the

software stroke limit.

• A target position change is carried

out during deceleration stop.

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

• The number of axes necessary for

interpolation operation is not
present in the unit.

• 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.

Interpolation mode
error

• For starting, a composite speed is

designated in the reference axis
parameter "Interpolation speed
designation method" using the
speed interpolation control or
4-axis linear interpolation control.

• For starting, a reference axis speed

is designated in the reference axis
parameter "Interpolation speed
designation method" using the
circular interpolation control.

At start: The system will 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.)
