Channel %1 master spindle not present in JOG mode
Parameters: %1 = Channel number
Definitions: The displayed axis is to be traversed as machine axis in JOG mode with revolutional feed,
but no master spindle has been defined from which the actual speed could have been
derived.
Reactions: - Local alarm reaction.
- Interface signals are set.
- Alarm display.
Remedy: Please inform the authorized personnel/service department. If the revolutional feed is also
to be active in JOG mode, then a master spindle must be declared via the channel-spe-
cific machine data 20090 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 feed, the control takes the value assigned in the
axis-specific MD 32050 JOG_REV_VELO or in the case of rapid traverse overlay 32040
JOG_REV_VELO_RAPID).
The revolutional feed in JOG mode is deactivated by changing the G function from G95 to
G94.
Program Con- Clear alarm with the Delete key or NC START.

Channel %1 axis %2 no revolutional feedrate possible. Axis/spindle %3 stationary
Parameters: %1 = Channel number
%2 = Axis name, spindle number
%3 = Axis name, spindle number
Definitions: An axis is to travel in JOG with revolutional feed, but the spindle/axis the feed is to be
derived from is 0.
Reactions: - Alarm display.
Remedy: Traverse the spindle/axis from which the feed is to be derived.
Program Con- Alarm display showing cause of alarm disappears. No further operator action necessary.
tinuation:
20057
Channel %1 block %2 revolutional feedrate for axis/spindle %3 is <= zero
Parameters: %1 = Channel number
%2 = Block number, label
%3 = Axis name, spindle number
Definitions: Revolutional feed has been programmed for an axis/spindle, but the velocity was not pro-
grammed or the programmed value is smaller than or equal to zero.
Reactions: - Correction block is reorganized.
- Local alarm reaction.
- Channel not ready.
- NC Start disable in this channel.
- Interface signals are set.
- Alarm display.
- NC Stop on alarm.
Remedy: Please inform the authorized personnel/service department.
• Correct the part program or
• Specify the correct feed for PLC axes at the VDI interface,
• Specify feed for oscillating axes in the setting data $SA_OSCILL_VELO.
Program Con- Clear alarm with the RESET key. Restart part program
