Block %2 Coupling To Master Spindle %3 Already Exists; Block %2 Coupling Parameter Not Changeable; Block %2 Cyclic Coupling; Block %2 Multiple Link - Siemens Sinamics S120 Diagnostic Manual

16786 [Channel %1: ] Block %2 coupling to master spindle %3 already exists
Parameters: %1 = Channel number
%2 = Block number, label
%3 = Leading spindle number
Definitions: A coupling is to be switched on, in which the slave axis is already actively coupled with the other master axis. Only
one master spindle is allowed for the synchronous spindle function. The already active master spindle is displayed as
last alarm parameter.
Reaction: 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 Clear alarm with NC START or RESET key and continue the program.
Continuation:
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.
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 Clear alarm with the RESET key. Restart part program
Continuation:
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_1
- 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.
