16760
Channel %1 block %2 axis %3 S value missing
Parameters:
%1 = Channel number
%2 = Block number, label
%3 = Axis name, spindle number
Definitions:
No spindle speed has been given for rigid tapping (G331 or G332).
Reaction:
Correction block is reorganized.
Interface signals are set.
Alarm display.
Remedy:
Program the spindle speed under address S in [rpm] (in spite of axis mode); the direction of rotation
is given by the sign of the spindle lead.
Positive thread lead: Rotational direction as M03.
Negative thread lead: Rotational direction as M04 N2.
Program
Continuation:
Clear alarm with NC START or RESET key and continue the program.
16761
Channel %1 block %2 axis/spindle %3 not programmable in the channel
Parameters:
%1 = Channel number
%2 = Block number, label
%3 = Axis name, spindle number
Definitions:
Mistake in programming: The axis/spindle cannot be programmed in the channel at this time. This
alarm can occur when the axis/spindle is being used by another channel or by the PLC.
Reaction:
Correction block is reorganized.
Interface signals are set.
Alarm display.
Remedy:
Modify part program, use "GET()".
Program
Continuation:
Clear alarm with NC START or RESET key and continue the program.
16762
Channel %1 block %2 spindle %3 thread function is active
Parameters:
%1 = Channel number
%2 = Block number, label
%3 = Spindle number
Definitions:
Mistake in programming: The spindle function cannot be executed at the present time. This alarm
occurs when the spindle (master spindle) is linked with the axes by an interpolation function.
Reaction:
Correction block is reorganized.
Interface signals are set.
Alarm display.
Remedy:
Modify part program. Deselect thread cutting or tapping.
Program
Continuation:
Clear alarm with NC START or RESET key and continue the program.
16763
Channel %1 block %2 axis %3 programmed speed is illegal (zero or
negative)
Parameters:
%1 = Channel number
%2 = Block number, label
%3 = Axis name, spindle number
Definitions:
A spindle speed (S value) was programmed with the value zero or with a negative value.
Reaction:
Correction block is reorganized.
Interface signals are set.
Alarm display.
Remedy:
The programmed spindle speed (S value) must be positive. Depending on the application case, the
value zero can be accepted (e.g. G25 S0).
Program
Continuation:
Clear alarm with NC START or RESET key and continue the program.
