SINUMERIK 802D sl, Diagnostics Manual, 06/2009

16777 [Channel %1: ] Block %2 coupling: following axis %3 for lead axis %4 not

available

Parameters: %1 = Channel number

%2 = Block number, label

%3 = Axis name, spindle number

%4 = Axis name, spindle number

Definitions: A coupling has been switched on in which the slave spindle/axis is currently not available. Possible

causes:

- The spindle/axis is active in the other channel.

- The spindle/axis has been accessed by the PLC and has not yet been released.

Reaction: NC Start disable in this channel.

Interface signals are set.

Alarm display.

NC Stop on alarm.

Remedy: Please inform the authorized personnel/service department. Put the master spindle/axis with spin-

dle/axis exchange into the necessary channel or release from the PLC.

Program Con-

tinuation:

Clear alarm with the RESET key. Restart part program

16778 [Channel %1: ] Block %2 coupling: Ring coupling at following axis %3

and leading axis %4 impermissible

Parameters: %1 = Channel number

%2 = Block number, label

%3 = Axis name, spindle number

%4 = Axis name, spindle number

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: NC Start disable in this channel.

Interface signals are set.

Alarm display.

NC Stop on alarm.

Remedy: Please inform the authorized personnel/service department. Configure link in accordance with the MD

or correct NC part program (MD21300 $MC_COUPLE_AXIS_1).

Program Con-

tinuation:

Clear alarm with the RESET key. Restart part program

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 mas-

ter 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 Con-

tinuation:

Clear alarm with NC START or RESET key and continue the program.

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 absolute position along the shortest path.

Example:

1 2 ... 126 127 128 129 130 131 132 133 134 135 136 ... 339 340
