SINUMERIK 802D sl, Diagnostics Manual, 06/2007Edition

26051 Channel %1 in block %2 unanticipated stop crossed in continuous path

mode

Parameters: %1 = Channel number

%2 = Block number, label

Definitions: The path interpolation did not stop, as required, at the end of the block, but will only decelerate to a

standstill in the next block. This error situation occurs if the stop at block change was not planned by

the path interpolation or was not detected early enough. A possible cause is that the PLC changed the

spindle speed when $MA_SPIND_ON_SPEED_AT_IPO_START > 0, and the machine has to wait

until the spindle has returned to the setpoint range. Another possible cause is that a synchronized

action needs to be finished before the path interpolation continues. The alarm is only output if

$MN_TRACE_SELECT = 'H400'. The alarm output is normally suppressed. - $MN_TRACE_SELECT

has SIEMENS password protection.

Reaction: Alarm display.

Remedy: $MA_SPIND_ON_SPEED_AT_IPO_START = 1. Program G09 before the alarm output in the block

to allow the path interpolation to stop as planned.

Program Con-

tinuation:

Clear alarm with the Delete key or NC START.

26052 Channel %1 in block %2: path velocity too high for auxiliary function

output

Parameters: %1 = channel number

%2 = block number, label

Definitions: This alarm usually occurs in a block with auxiliary function output during a movement. In this case, the

wait for acknowledgement of the auxiliary function was longer than planned.

The alarm occurs if internal control inconsistencies cause continuous path mode (G64, G641, ...) to

be blocked unexpectedly.

The path interpolation stops abruptly at the end of the block indicated in the message (regenerative

stop). On the next block change, the path continues unless the abrupt stop has caused an error in the

position controller (e.g. because the MD 36400 CONTOUR_TOL setting was over-sensitive).

Reaction: Alarm display.

Remedy: Program G09 in the block indicated in the message to allow the path interpolation to stop as planned.

Program Con-

tinuation:

Clear alarm with the Delete key or NC START.

26070 Channel %1 axis %2 cannot be controlled by the PLC, max. number

exceeded

Parameters: %1 = channel number

%2 = axis name, spindle number

Definitions: An attempt has been made to control more axes than allowed from the PLC.

Reaction: Interface signals are set.

Alarm display.

Remedy: Check the machine data MD_NUM_MAX_PLC_CNTRL_AXES and correct if necessary or reduce the

number of PLC-controlled axes.

Program Con-

tinuation:

Clear alarm with the Delete key or NC START.

26072 Channel %1 axis %2 cannot be controlled by the PLC

Parameters: %1 = channel number

%2 = axis name, spindle number

Definitions: The axis cannot be made a PLC-controlled axis. For the time being, the axis cannot be controlled at

any state from the PLC.

Reaction: Interface signals are set.

Alarm display.

Remedy: Use Release or Waitp to make the axis a neutral one.

Program Con-

tinuation:

Clear alarm with the Delete key or NC START.
