Siemens SINUMERIK 808D ADVANCED Diagnostic Manual page 321

Explanation: The machine kinematics does not allow the specified motion. Transformation-dependent error causes can be in:
TRANSMIT: A (circular) area exists around the pole, where positioning is not possible. The area is caused by the fact that
the tool reference point cannot be traversed as far as into the pole. The area is defined by:
- the machine data (MD249.. $MC_TRANSMIT_BASE_TOOL_...)
- the active tool length compensation (see $TC_DP..).
Whether the tool length compensation is included in the calculation depends on the working plane selected (see G17,..).
The machine stops at the edge of the area where positioning is not possible.
Reaction: Local alarm reaction.
NC Start disable in this channel.
Interface signals are set.
Alarm display.
NC Stop on alarm.
Remedy: Modify part program. Change the incorrectly specified tool length compensation.
Note: RESET alone is not enough if transformation also remains active during RESET.
Programm Clear alarm with the RESET key. Restart part program

21620 [Channel %1: ] Axis %2 Emergency braking ramp activated
Parameters: %1 = Channel number
%2 = Axis name, spindle number
Explanation: An axial emergency braking ramp was activated for the specified axis/spindle
The following causes are possible for the activation of the emergency braking ramp:
Alarm 26052: Path velocity for auxiliary function output too high
Alarm 1012 : System error with ID 550006 550006
Alarm 1016 : System error with ID 550003, 550005 and 550010
With master/slave coupling, MD30132 $MA_IS_VIRTUAL_AX (axis is virtual axis) has been set.
Braking request with priority 13 may have been requested by the OEM application.
Reaction: NC Start disable in this channel.
Local alarm reaction.
The NC switches to follow-up mode.
Interface signals are set.
Alarm display.
Remedy: Please inform the authorized personnel/service department. Remove or reset the cause of the alarm.
Programm Clear alarm with the RESET key. Restart part program
continuation:
21650 [Channel %1: ] Axis %2 overlaid motion not allowed
Parameters: %1 = Channel number
%2 = Axis name, spindle number
Explanation: An overlaid motion was requested for the axis, however, this is not allowed due to the MD32074
$MA_FRAME_OR_CORRPOS_NOTALLOWED.
Reaction: Local alarm 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. Deselect the overlaid motion or change MD32074
$MA_FRAME_OR_CORRPOS_NOTALLOWED.
Programm Clear alarm with the RESET key. Restart part program
