- NC Start disable in this channel.
- Alarm display.
- Interface signals are set.
- NC Stop on alarm.
- The NC switches to follow-up mode.
- If the axis is a single axis when this alarm is triggered, the alarm is only effective for this
axis (not effective for e.g. the channel or mode group)
Please inform the authorized personnel/service department. Check the interface signal
"Servo enable" (DB31 - 48, DBX 2.1, e.g. with the PLC status display in the DIAGNOS-
TICS operating area). Trace back the signal to the sections in the PLC user program at
which it is linked and set/reset.
With SAFETY: With active actual-value linkage, the output of the error message on the
slave axis can be prevented by increasing MD 36060 $MA_STANDSTILL_VELO_TOL to
100 and 200 (default value is 5 mm).
Clear alarm with the Delete key or NC START.
Axis %1 measuring system changing
%1 = Axis name, spindle number
The measuring system for this axis is changing.
- Alarm display.
-
Alarm display showing cause of alarm disappears. No further operator action
Channel %1 axis %2 hardware limit switch %3
%1 = Channel number
%2 = Axis name, spindle number
%3 = String (+, - or +/-)
The VDI signal "Hardware limit switch" (DB 31 - 48, DBX 12.0 or DBX 12.1) has been set
at the NC/PLC interface.
- Alarm display.
- NC Start disable in this channel.
Please inform the authorized personnel/service department.
1. With axes that have already been referenced, the software limit switch 1 or 2 should
respond before the hardware limit switch is reached. Check MD 36110
POS_LIMIT_PLUS, 36100 POS_LIMIT_MINUS, 36130 POS_LIMIT_PLUS2 and 36120
POS_LIMIT_MINUS2 and the interface signal for selection of 1st/2nd software limit switch
(DB 31 - 48, DBX 12.2 and 12.3) and correct if necessary (PLC user program).
2. If the axis has not yet been moved to the reference point, it is possible to depart from
the hardware limit switch in the opposite direction in JOG mode.
3. Check PLC user program and the connection from the switch to the PLC input module,
provided the axis has not yet reached the hardware limit switch at all.
Clear alarm with the RESET key. Restart part program
Channel %1 axis %2 taken from traverse mode to follow-up mode
%1 = Channel number
%2 = Axis name, spindle number
This axis has been taken from traverse mode and put into "Follow-up" mode, for instance
because the pulse enable for the drive has been reset.
