YASNAC PCNC Programming Manual Chapter 3: Movement Control Commands
Table 3.2.3.2 Alarm Codes
• The workpiece coordinate system rotation, mirror image, and scaling functions must
be specified in a predetermined order when they are specified in the same block. If
this order is disregarded, alarm “0285” occurs.
Workpiece coordinate > Mirror image > Scaling > Coordinate system
system rotation rotation
(G54) (M94) (G51) (G68)
• If scaling is called in the mirror image mode, mirror image is applied to the center of
scaling.
• If coordinate system rotation is called in the scaling mode, scaling is applied to the
center of rotation. However, scaling is not valid for the angle of rotation.
Alarm No. Description

specified.
0281
Scaling format error • In the G50 or G51 block, a command that is not allowed
is specified.
• Scaling factor is “0”.
