Channel %1 block %3 spindle %2 gear step change position not reached
%1 = Channel number
%2 = Spindle number
%3 = Block number, label
Through the configuration of MA_GEAR_STEP_CHANGE_ENABLE[AXn] = 2, the spin-
dle is traversed to the position stored in MA_GEAR_STEP_CHANGE_POSITION[AXn]
before the actual gear step change. The required gear step change position has not been
reached.
- Channel not ready.
- NC Start disable in this channel.
- Interface signals are set.
- Alarm display.
- NC Stop on alarm.
Correct sequence in the PLC.
Clear alarm with the RESET key. Restart part program
Channel %1 block %2 spindle %3 incorrect gear stage during axis operation
%1 = Channel number
%2 = Block number, label
%3 = Spindle
In machine date 35014 $MA_GEAR_STEP_USED_IN_AXISMODE, a gear stage has
been configured in which the spindle is to be positioned during axis operation. The NC will
check for this gear stage whenever the spindle is switched over into axis operation. The
gear stage configured in MD 35014 is compared with the gear stage output by the PLC
(VDI interface "Actual gear stage A through C", DB31, ... DBX 16.0..16.2). If the gear
stages are not the same, this alarm will be output. On changeover into axis operation with
programming of M70, the NC automatically sets or requests the gear stage configured in
MD 35014. If the gear stage configured in MD 35014 is already active, a gear stage
change will not be requested. M40 will remain active in both cases.
- Interface signals are set.
- Alarm display.
Program M70 prior to axis operation. Consider MD 20094.
Clear alarm with the Delete key or NC START.
Channel %1 block %2 following spindle %3 Impermissible programming
%1 = Channel number
%2 = Block number, label
%3 = Spindle
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 miss-
ing. If dimensional accuracy or reproducibility are not important, the alarm can be sup-
pressed with machine data 11410 SUPPRESS_ALARM_MASK Bit27 = 1.
- NC Start disable in this channel.
- Interface signals are set.
- Alarm display.
- NC Stop on alarm.
Use synchronous spindle-DV-coupling or program direction of rotation and speed.
Clear alarm with the RESET key. Restart part program
