Reactions: - Correction block is reorganized.
- Interface signals are set.
- Alarm display.
Remedy: Prior to switching on the new coupling, separate the existing coupling. If several master
spindels/axes are required, the ELG function will have to be used.
Program Con- Clear alarm with NC START or RESET key and continue the program.
tinuation:
16787
Channel %1 block %2 coupling parameter not changeable
Parameters: %1 = Channel number
%2 = Block number, label
Definitions: The specified coupling is write-protected. Therefore, the coupling parameters cannot be
modified.
Reactions: - 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. Channel MD: COUPLE_AXIS_IS_WRITE_PROT
• 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.
Reactions: - 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 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.
Reactions: - 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
