16788 Channel %1 block %2 cyclic coupling
Parameters: %1 = Channel number
%2 = Block number, label
Definitions: A coupling has been switched on which results in a cyclic coupling, allowance being made for further
couplings. This cyclic coupling cannot be uniquely computed.
Reaction: Correction block is reorganized.
Interface signals are set.
Alarm display.
Remedy: Please inform the authorized personnel/service department.
- Configure link accordingly in MD (channel MD: 21300 COUPLE_AXIS_n)
- or modify part program.
Program Clear alarm with NC START or RESET key and continue the program.
Continuation:
16789 Channel %1 block %2 multiple link
Parameters: %1 = Channel number
%2 = Block number, label
Definitions: A coupling has been switched on in which the axes/spindles have already been assigned by another
coupling. Parallel couplings cannot be processed.
Reaction: Correction block is reorganized.
Interface signals are set.
Alarm display.
Remedy: Check in the part program whether another link already exists for the axes.
Program Clear alarm with NC START or RESET key and continue the program.
Continuation:
16790 Channel %1 block %2 Parameter is zero or missing
Parameters: %1 = Channel number
%2 = Block number, label
Definitions: A coupling has been switched on in which a relevant parameter has been specified with zero or has
not been written (e.g. denominator in the transmission ratio, no slave axis).
Reaction: Correction block is reorganized.
Interface signals are set.
Alarm display.
Remedy: Please inform the authorized personnel/service department.
- Configure link accordingly in MD (channel MD: 42300 COUPLE_RATIO_n)
- or modify part program.
Program Clear alarm with NC START or RESET key and continue the program.
Continuation:
16791 Channel %1 block %2 parameter is not relevant
Parameters: %1 = Channel number
%2 = Block number, label
Definitions: A coupling has been switched on in which a non-relevant parameter has been written (e.g. parameter
for ELG).
Reaction: Correction block is reorganized.
Interface signals are set.
Alarm display.
Remedy: Modify part program.
Program Clear alarm with NC START or RESET key and continue the program.
