Overview of Alarms
16730
Channel %1 block %2 axis %3 wrong parameter
Parameters: %1 = Channel number
%2 = Block number, label
%3 = Axis name, spindle number
Definitions: In G33 (tapping with constant lead) the lead parameter was not assigned to the axis that
determines the velocity.
For longitudinal and face threads, the thread lead for the specified geometry axis must be
programmed under the associated interpolation parameter.
X -> I
Y -> J
Z -> K
For taper threads, the address I, J, K depends on the axis with the longer path (thread
length). A 2nd lead for the other axis is, however, not specified.
Reactions: - Correction block is reorganized.
- Interface signals are set.
- Alarm display.
Remedy: Assign lead parameters to the axis that determines the velocity.
Program Con- Clear alarm with NC START or RESET key and continue the program.
tinuation:
16740
Channel %1 block %2 no geometry axis programmed
Parameters: %1 = Channel number
%2 = Block number, label
Definitions: No geometry axis was programmed for tapping (G33) or for rigid tapping (G331, G332).
The geometry axis is, however, essential if an interpolation parameter has been specified.
Example:
N100 G33 Z400 K2 ; thread lead 2mm, thread end Z=400 mm
N200 SPOS=0 ; position spindle in axis mode
N201 G90 G331 Z-50 K-2 ; tapping to Z=-50, counterclockwise
N202 G332 Z5 ; retraction, direction reversal automatic
N203 S500 M03 ; spindle again in spindle mode
Reactions: - Correction block is reorganized.
- Interface signals are set.
- Alarm display.
Remedy: Specify geometry axis and corresponding interpolation parameters.
Program Con- Clear alarm with NC START or RESET key and continue the program.
tinuation:
16750
Channel %1 block %2 axis %3 SPCON not programmed
Parameters: %1 = Channel number
%2 = Block number, label
%3 = Axis name, spindle number
Definitions: For the programmed function (rotary axis, positioning axis), the spindle must be in posi-
tion control mode.
Reactions: - Correction block is reorganized.
- Interface signals are set.
- Alarm display.
Remedy: Program position control of the spindle with SPCON in the previous block.
Program Con- Clear alarm with NC START or RESET key and continue the program.
tinuation:
