20062 [Channel %1: ] Axis %2 already active
Parameters: %1 = Channel number
%2 = Axis name, spindle number
Definitions: The displayed axis is already traversing as a machine axis. Therefore, it cannot be operated as a geometry axis.
Traversing an axis can take place in JOG mode through 2 different interfaces.
1. As a geometry axis: via the channel-specific interface DB3200 DBX1000.7 / 0.6 (Traversing keys -/+)
2. As a machine axis: via the axis-specific interface DB380x DBX4.7 / 4.6 (Traversing keys plus/minus)
With the standard machine control panel, it is not possible to operate an axis as a machine axis and as a geometry
axis at the same time.
Reaction: Alarm display.
Remedy: Do not start the geometry axis until the traversing motion as machine axis has been concluded.
Program Clear alarm with the Delete key or NC START.
Continuation:
20064 [Channel %1: ] Axis %2 selection of several axes with an active taper angle is not
permitted.
Parameters: %1 = Channel number
%2 = Axis name, spindle number
Definitions: With an active taper angle, only one geometry axis at the time can be traversed in JOG mode by pressing traversing
keys. Simultaneous traversing of a geometry axis as a machine axis is not permitted either.
Reaction: NC not ready.
Interface signals are set.
Alarm display.
NC Stop on alarm.
Remedy: Starting the geometry axis only if traversing of the other geometry axis or machine axis completed.
Program Clear alarm with the RESET key. Restart part program
Continuation:
20065 [Channel %1: ] Master spindle not defined for geometry axes in JOG mode
Parameters: %1 = Channel number
Definitions: The displayed axis is to be traversed as geometry axis in JOG mode with rotary feed, but no master spindle has been
defined from which the actual speed could be derived.
Reaction: Local alarm reaction.
Interface signals are set.
Alarm display.
Remedy: If the revolutional feedrate is to be active in JOG mode too, then a master spindle must be declared in the channel-
specific machine data MD20090 $MC_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 feedrate, the control takes the
value assigned in the axis-specific machine data MD32050 $MA_JOG_REV_VELO or in the case of rapid traverse
override MD32040 $MA_JOG_REV_VELO_RAPID).
The revolutional feedrate 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:
20070 [Channel %1: ] Axis %2 software limit switch %3 programmed end position %4
Parameters: %1 = Channel number
%2 = Axis number
%3 = "1+" or "1-" for software limit switches 1, "2+" or "2-" for software limit switch 2,
%4 = Programmed end position
Definitions: The axis is to be traversed by the PLC as a concurrent positioning axis to the limit position. This would violate the
corresponding software limit switch for the axis. No traversing takes place.
With an additional message to alarm 20140, the axis is to be traversed as a command axis.
Reaction: Alarm display.
