Overview of Alarms
NCK alarms
20055 Channel %1 master spindle not present in JOG mode
Parameters: %1 = Channel number
Definitions: The displayed axis is to be traversed as machine axis in JOG mode with revolutional feed, but no
master spindle has been defined from which the actual speed could have been derived.
Reaction: Local alarm reaction.
Interface signals are set.
Alarm display.
Remedy: Please inform the authorized personnel/service department. If the revolutional feed is also to be active
in JOG mode, then a master spindle must be declared via the channel-specific machine data 20090
SPIND_DEF_MASTER_SPIND. In this case you have to open a screen in the PARAMETER
operating area with the softkeys "SETTINGDATA" and "JOG DATA" and preselect the G function G95
there. The JOG feedrate can then be entered in [mm/rev]. (If 0 mm/rev is set as JOG feed, the control
takes the value assigned in the axis-specific MD 32050 JOG_REV_VELO or in the case of rapid
traverse overlay 32040 JOG_REV_VELO_RAPID).
The revolutional feed in JOG mode is deactivated by changing the G function from G95 to G94.
Program Clear alarm with the Delete key or NC START.
Continuation:
20056 Channel %1 axis %2 no revolutional feedrate possible. Axis/spindle %3
stationary
Parameters: %1 = Channel number
%2 = Axis name, spindle number
%3 = Axis name, spindle number
Definitions: An axis is to travel in JOG with revolutional feed, but the spindle/axis the feed is to be derived from is 0.
Reaction: Alarm display.
Remedy: Traverse the spindle/axis from which the feed is to be derived.
Program Alarm display showing cause of alarm disappears. No further operator action necessary.
Continuation:
20057 Channel %1 block %2 revolutional feedrate for axis/spindle %3 is <= zero
Parameters: %1 = Channel number
%2 = Block number, label
%3 = Axis name, spindle number
Definitions: Revolutional feed has been programmed for an axis/spindle, but the velocity was not programmed or
the programmed value is smaller than or equal to zero.
Reaction: Correction block is reorganized.
Local alarm reaction.
Channel not ready.
NC Start disable in this channel.
Interface signals are set.
Alarm display.
NC Stop on alarm.
Remedy: Please inform the authorized personnel/service department.
- Correct the part program or
- Specify the correct feed for PLC axes at the VDI interface,
- Specify feed for oscillating axes in the setting data $SA_OSCILL_VELO.
Program Clear alarm with the RESET key. Restart part program
