Channel %1 axis %2 reference point approach requires second referenced measur-
ing system
%1 = Channel number
%2 = Axis name, spindle number
When setting 34200 ENC_REFP_MODE = 6 the 2nd encoder must first be referenced.
- NC Stop on alarm.
- NC Start disable in this channel.
- Alarm display.
- Interface signals are set.
Modify referencing mode ENC_REFP_MODE or reference 2nd encoder.
Clear alarm with the RESET key. Restart part program
Channel %1 axis %2 handwheel mode active
%1 = Channel number
%2 = Axis name, spindle number
The axes cannot be traversed in JOG mode using the traversing keys because traversing
is still taking place via the handwheel.
- Alarm display.
Decide whether the axis is to be traversed by means of the jog keys or via the handwheel.
End handwheel travel and delete the axial distance-to-go if necessary (interface signal
DB 31 - 48, DBX 2.2).
Alarm display showing cause of alarm disappears. No further operator action
Channel %1 axis %2 handwheel mode not possible
%1 = Channel number
%2 = Axis name, spindle number
The axis is already traveling via the traversing keys, so handwheel mode is no longer pos-
sible.
- Alarm display.
Decide whether the axis is to be traversed by means of the jog keys or via the handwheel.
Alarm display showing cause of alarm disappears. No further operator action
Channel %1 axis %2 already active
%1 = Channel number
%2 = Axis name, spindle number
The axis is to traverse as machine axis in JOG mode via the jog keys on the machine con-
trol panel. However, this is not possible because:
1. It is already traversing as geometry axis (through the channel-specific interface DB 21 -
28, DBX 12.6, DBX 12.7, DBX 16.6, DBX 16.7 or DBX 20.6 and DBX 20.7) or
2. it is already traversing as machine axis (through the axis-specific interface DB 31 - 48,
DBX 4.6 and DBX 4.7) or
3. a frame is valid for a rotated coordinate system and another geometry axis involved in
this is already traversing in JOG mode by means of the direction keys.
- Alarm display.
Stop traversing through the channel or axis interface or stop the other geometry axis.
Clear alarm with the Delete key or NC START.
