6 Maintenance and Inspection
6.5.1 Motion Program Alarm Configuration
6-24
6.5 Motion Program Alarms
If the result of investigation using
6.3.2 MP2300 Error Check Flowchart
on page 6-6 indicates that a motion program
alarm has occurred, use the alarm code to determine the cause of the error.
6.5.1 Motion Program Alarm Configuration
Motion program alarms stored in the alarm output register (default: SW03268) are displayed as shown in the following
diagram.
Refer to the appropriate User’s Manual of Machine Controller for information on finding the alarm output register.
6.5.2 Motion Program Alarm Code List
The motion program alarm codes are listed in the following table.
When displaying these on the register list, set the view mode to hexadecimal.
Bit 0
Bit 7
Bit 8
Bit 12
Bit 15

02h
Division error
Data divided by 0
Review the motion program.
10h
A circle instead of
radius was specified
Turn number was specified instead of radius in
the circular arc or helical interpolation
command.
• Designate a center coordinate instead of a
radius to perform the circular arc or
helical interpolation command.
• Never specify the turn number.
11h
Interpolation feeding
speed over limit
Interpolation feeding speed exceeded the valid
range of the FMX command.
Modify the interpolation feeding speed of
the interpolation command
12h
No interpolation feeding
speed specified
No interpolation feeding speed was specified.
(once specified, this can be omitted as in the
motion program)
Specify the interpolation feeding speed in
the interpolation command.
13h
Range exceeded after
converting acceleration
parameter
Indirect acceleration parameter exceeded the
valid range.
Change the indirect register value.
14h
Circular arc length
exceeded LONG_MAX
Circular arc length exceeded the valid range in
the circular arc or helical interpolation
command.
Review the circular arc length in the
circular arc or helical interpolation
command.
15h
Vertical axis not
specified for circular arc
plane
Vertical axis was not specified in the circular
arc or helical interpolation command.
Use PLN command to specify the axis.
16h
Horizontal axis not
specified for circular arc
plane
Horizontal axis was not specified in the
circular arc or helical interpolation command.
Use PLN command to specify the axis.
17h
Specified axis over limit
Too many axes were configured in the circular
arc (two axes) or helical (three axes)
interpolation command.
Modify the axis in the circular arc or helical
interpolation command.
18h
Turn number over limit
Turn number exceeded the valid range in the
circular arc or helical interpolation command.
Modify the turn number in the circular arc
or helical interpolation command.
19h
Radius exceeded
LONG_MAX
Radius exceeded the valid range in the circular
arc or helical interpolation command.
Review the radius in the circular arc or
helical interpolation command.
1Ah
Center point error
Improper center point was specified in the
circular arc or helical interpolation command.
Specify the center point properly in the
circular arc or helical interpolation
command.
1Bh
Running emergency
stop command
Axis move command stopped due to a
program stop request.
Turn OFF the program stop request for the
motion program control signal, and turn
ON the alarm reset request.
1Ch
Linear interpolation
moving amount
exceeded LONG_MAX
Moving amount exceeded the valid range in
the linear interpolation command.
Review the moving amount in the linear
interpolation command.
