22011 Channel %1 block %3 spindle %2 change to programmed gear stage not
possible
Parameters: %1 = channel number
%2 = spindle number
%3 = block number, label
Definitions: With the 'DryRun' and 'ProgramTest' functions deselected, it is not possible in the Repos module to
carry out a gear stage change to a previously programmed gear stage. This is the case if the spindle
in the deselection block is not operating in speed control mode or not active as a following axis or in
a transformation. Retro-execution of a gear stage change when the above mentioned functions are
deselected can be avoided by resetting bit 2 of machine data 35035 SPIND_FUNCTION_MASK.
Reaction: Alarm display.
Remedy: Change deselection block or block search target block to speed control mode (M3, M4, M5, SBCOF).
Program Con-
tinuation:
Clear alarm with the Delete key or NC START.
22020 Channel %1 block %3 spindle %2 gear step change position not reached
Parameters: %1 = channel number
%2 = spindle number
%3 = block number, label
Definitions: Through the configuration of MA_GEAR_STEP_CHANGE_ENABLE[AXn] = 2, the spindle is tra-
versed to the position stored in MA_GEAR_STEP_CHANGE_POSITION[AXn] before the actual gear
stage change. The required gear stage change position has not been reached.
Reaction: Channel not ready.
NC Start disable in this channel.
Interface signals are set.
Alarm display.
NC Stop on alarm.
Remedy: Correct sequence in the PLC.
Program Con-
tinuation:
Clear alarm with the RESET key. Restart part program
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
Definitions: A gear stage for spindle operation in axis mode is configured in machine data 35014
GEAR_STEP_USED_IN_AXISMODE. The NC checks that this gear stage is engaged when the spin-
dle is switched to this gear stage. It does this by comparing the gear stage configured in MD 35014
with the actual gear stage returned by the PLC (VDI interface "Actual gear stage A to C", V38002000.0
… 2). If the gear stages are not identical, this alarm is generated. When the spindle switches to axis
mode in response to a programmed M70 command, the NC automatically engages or requests the
gear stage configured in MD 35014. If the gear stage in this MD is already active, no gear stage
change is requested. M40 remains active in both cases.
Reaction: Interface signals are set.
Alarm display.
Remedy: Program M70 before axis mode. Note MD 20094.
Program Con-
tinuation:
Clear alarm with the Delete key or NC START.
22040 Channel %1 block %3 spindle %2 is not referenced with zero marker
Parameters: %1 = channel number
%2 = axis name, spindle number
%3 = block number, label
Definitions: The current position is not referenced with the measuring system position although reference is made
to it.
Reaction: Alarm display.
Remedy: Correct NC part program. Establish zero mark synchronization by positioning, by rotation (at least 1
revolution) in speed control mode or G74 before switching the alarm generating function on.
