Definitions: The specified coupling is write-protected. Therefore, the coupling parameters cannot be modified.
Reaction: Interpreter stop
NC Start disable in this channel.
Interface signals are set.
Alarm display.
Remedy: Please inform the authorized personnel/service department.
- Remove write protection (see channel MD21340 $MC_COUPLE_IS_WRITE_PROT_1)
- or modify part program.
Program Con- Clear alarm with the RESET key. Restart part program
tinuation:
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 MD21300 $MC_COUPLE_AXIS_1n)
- or modify part program.
Program Con- Clear alarm with NC START or RESET key and continue the program.
tinuation:
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 Con- Clear alarm with NC START or RESET key and continue the program.
tinuation:
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 SD42300 $SC_COUPLE_RATIO_1
- or correct part program.
Program Con- Clear alarm with NC START or RESET key and continue the program.
tinuation:
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.
