Definitions: For the programmed function, the spindle must be in the open-loop control mode. In the positioning
or axis mode, the position control must not be deselected.
Reaction: Correction block is reorganized.
Interface signals are set.
Alarm display.
Remedy: Put the spindle into open-loop control mode in the preceding block. This can be done with M3, M4 or
M5 for the relevant spindle.
Program Con- Clear alarm with NC START or RESET key and continue the program.
tinuation:
16755 [Channel %1: ] Block %2 no stop required
Parameters: %1 = Channel number
%2 = Block number, label
Definitions: No Stop is needed for the programmed function. A Stop is necessary after SPOSA or after M5 if the
next block is to be loaded only after a spindle stop.
Reaction: Correction block is reorganized.
Interface signals are set.
Alarm display.
Remedy: Do not write instruction.
Program Con- Clear alarm with NC START or RESET key and continue the program.
tinuation:
16757 [Channel %1: ] Block %2 for following spindle %3 coupling as leading
spindle/axis already existing
Parameters: %1 = Channel number
%2 = Block number, label
%3 = Following spindle number
Definitions: A coupling has been switched on in which the following spindle/axis has already been active as lead-
ing spindle/axis in another coupling. Chained couplings cannot be processed.
Reaction: Correction block is reorganized.
Interface signals are set.
Alarm display.
Remedy: Check in the parts program whether the following spindle/axis is already active as leading spindle/axis
in another coupling.
Program Con- Clear alarm with NC START or RESET key and continue the program.
tinuation:
16758 [Channel %1: ] Block %2 for leading spindle %3 coupling as following
spindle/axis already existing
Parameters: %1 = Channel number
%2 = Block number, label
%3 = Leading spindle number
Definitions: A coupling has been switched on in which the leading spindle/axis has already been active as follow-
ing spindle/axis in another coupling. Chained couplings cannot be processed.
Reaction: Correction block is reorganized.
Interface signals are set.
Alarm display.
Remedy: Check in the parts program whether the leading spindle/axis is already active as following spindle/axis
in another coupling.
Program Con- Clear alarm with NC START or RESET key and continue the program.
tinuation:
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.
