Block %2 Coupling Is Active; Block %2 Traverse Instruction Dc/Cdc For Axis %3 Not Allowed; Block %2 Traverse Instruction Acp For Axis %3 Not Allowed - Siemens Sinamics S120 Diagnostic Manual

NCK alarms
Program Clear alarm with NC START or RESET key and continue the program.
Continuation:
16797 [Channel %1: ] Block %2 coupling is active
Parameters: %1 = Channel number
%2 = Block number, label
Definitions: An operation is to be performed in which no coupling may be active, e.g. COUPDEL or TANGDEL must not be used
on active couplings.
Reaction: Correction block is reorganized.
Interface signals are set.
Alarm display.
Remedy: Correct NC part program, deselect the link with COUPOF or TANGOF.
Program Clear alarm with NC START or RESET key and continue the program.
Continuation:
16800 [Channel %1: ] Block %2 traverse instruction DC/CDC for axis %3 not allowed
Parameters: %1 = Channel number
%2 = Block number, label
%3 = Axis name, spindle number
Definitions: The keyword DC (Direct Coordinate) can only be used for rotary axes. This causes approach of the programmed abso-
lute position along the shortest path.
Example:
N100 C=DC(315)
Reaction: Correction block is reorganized.
Interface signals are set.
Alarm display.
Remedy: Please inform the authorized personnel/service department.
Replace the keyword DC in the displayed NC block by specifying AC (Absolute Coordinate).
If the alarm display is the result of an error in the axis definition, the axis can be declared as a rotary axis by means of
the axis-specific MD30300 $MA_IS_ROT_AX.
Corresponding machine data:
Modify MD30310: $MA_ROT_IS_MODULO
Modify MD30320: $MA_DISPLAY_IS_MODULO
Program Clear alarm with NC START or RESET key and continue the program.
Continuation:
16810 [Channel %1: ] Block %2 traverse instruction ACP for axis %3 not allowed
Parameters: %1 = Channel number
%2 = Block number, label
%3 = Axis name, spindle number
Definitions: The keyword ACP (Absolute Coordinate Positive) is only allowed for "modulo axes". It causes approach of the pro-
grammed absolute position in the specified direction.
Reaction: Correction block is reorganized.
Interface signals are set.
Alarm display.
Remedy: Please inform the authorized personnel/service department.
In the displayed NC block, replace the keyword ACP by specifying AC (Absolute Coordinate).
If the alarm display is based on an incorrect axis definition, the axis with the axis-specific MD30300 $MA_IS_ROT_AX
and MD30310 $MA_ROT_IS_MODULO can be declared a rotary axis with modulo change.
Corresponding machine data:
Modify MD30320 $MA_DISPLAY_IS_MODULO
