20211 Channel %1 block %3 spindle %2 support point beyond range limits

Parameters: %1 = Channel number

%2 = Spindle number

%3 = Block number, label

Definitions: The support point calculated for centerless grinding is beyond the range limits.

Machine data:

Modify MD 21518: TRACLG_CONTACT_UPPER_LIMIT

Modify MD 21520: TRACLG_CONTACT_LOWER_LIMIT

Reaction: Alarm display.

Remedy: - Check centerless axis positions and machine data.

- Modify program.

- Select new traversing positions for centerless axes

- or suppress computation by G00.

Program Con-

tinuation:

Alarm display showing cause of alarm disappears. No further operator action necessary.

20300 Channel %1 axis %2 orientation not possible

Parameters: %1 = Channel number

%2 = Axis name, spindle number

Definitions: On traversing the displayed (virtual) orientation axis, a tool orientation is to be set

for which the kinematics of this machine are not possible.

Reaction: Alarm display.

Remedy: Abort the JOG movement and specify another (possible)

change of orientation.

Program Con-

tinuation:

Clear alarm with the Delete key or NC START.

21550 Channel %1 axis %2 Travel from hardware limit switch not possible.

Reason: %3

Parameters: %1 = channel number

%2 = axis name

%3 = cause

Definitions: An attempt has been made to retract a coupled following axis or an output axis in a transformation via

the leading axis or input axis in a transformation. This is not allowed in the current situation.

Possible causes:

1 Retraction direction not legal

2 Coupling not synchronized

3 Retraction not legal for the active coupling

4 Reserved

5 Retraction not legal for the active transformation

Reaction: NC Start disable in this channel.

Alarm display.

Remedy: Remedy of error cause:

1 Specify a different travel direction

2 Deactivate the coupling and move axis(axes) separately

3 Deactivate the coupling and move axis(axes) separately

4 Reserved

5 Deactivate the transformation and move axis(axes) separately

Program Con-

tinuation:

Clear alarm with the RESET key. Restart part program

21600 Monitoring for ESR active

Definitions: -

Reaction: NC not ready.

Alarm display.

All alarm reactions are delayed by one IPO cycle with this alarm.

Remedy: The display can be suppressed with the machine data MD 11410: SUPPRESS_ALARM_MASK Bit 16

= 1

Program Con-

tinuation:

Alarm display showing cause of alarm disappears. No further operator action necessary.
