Overview of Alarms
NCK alarms
22022 Channel %1 block %2 spindle %3 gear stage %4 is expected for axis
mode.
Parameters: %1 = Channel number
%2 = Block number, label
%3 = Spindle
%4 = Gear stage
Definitions: The gear stage required for axis mode has not been installed.
A gear stage has been configured in machine data 35014 GEAR_STEP_USED_IN_AXISMODE, in
which the spindle is to be in axis mode. This gear stage is checked whenever the spindle is switched
into axis mode. The configured gear stage is compared with the gear stage output by the PLC (VDI
interface "Actual gear stage A through C", DB31, ... DBX 16.0..16.2).
This alarm will be output if the gear stages are not the same.
Reaction: Interface signals are set.
Alarm display.
Remedy: Program M70 before the switch to axis mode. The gear stage configured in MD 35014
GEAR_STEP_USED_IN_AXISMODE is then automatically loaded.
No gear stage change is required if the configured gear stage is aleady active. M40 remains active
beyond the gear stage change.
Consider MD 20094 SPIND_RIGID_TAPPING_M_NR.
Program Clear alarm with the Delete key or NC START.
Continuation:
22030 Channel %1 block %2 following spindle %3 Impermissible programming
Parameters: %1 = Channel number
%2 = Block number, label
%3 = Spindle
Definitions: With synchronous spindle-VV-coupling an additional motion for the following spindle can only be
programmed with M3, M4, M5 and S... The paths created by specified positions cannot be maintained
safely for a velocity coupling, especially if a position control is missing. If dimensional accuracy or
reproducibility are not important, the alarm can be suppressed with machine data 11410
SUPPRESS_ALARM_MASK Bit27 = 1.
Reaction: NC Start disable in this channel.
Interface signals are set.
Alarm display.
NC Stop on alarm.
Remedy: Use synchronous spindle-DV-coupling or program direction of rotation and speed.
Program Clear alarm with the RESET key. Restart part program
