Overview of Alarms
NCK alarms
21619 [Channel %1: ] Block %2 transformation active: motion not possible
Parameters: %1 = Channel number
%2 = Block number, label
Definitions: 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.
Program Con- Clear alarm with the RESET key. Restart part program
tinuation:
21620 [Channel %1: ] Axis %2 Emergency braking ramp activated
Parameters: %1 = Channel number
%2 = Axis name, spindle number
Definitions: The axial emergency braking ramp has been activated for the specified axis/spindle
The following causes are possible for activation of the emergency braking ramp:
Alarm 26052: Path velocity for auxiliary function output too high
Alarm 1012 : System error with ID 550006
Alarm 1016 : System error with ID 550003, 550005 and 550010
Context-sensitive braking request with priority 13 is active
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.
Program Con- Clear alarm with the RESET key. Restart part program
tinuation:
21650 [Channel %1: ] Axis %2 overlaid motion not allowed
Parameters: %1 = Channel number
%2 = Axis name, spindle number
Definitions: 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.
Program Con- Clear alarm with the RESET key. Restart part program
tinuation:
21660 [Channel %1: ] Block %2 axis %3 conflict between SYNACT: $AA_OFF
and CORROF
Parameters: %1 = Channel number
%2 = Block number, label
%3 = Axis name
