Axis %1 acceptance test mode is active
%1 = Axis number
Via the operator panel, an SI acceptance test has been started for example with the
acceptance test wizard. The acceptance test mode is activated via the NCK and drive for
the time of this acceptance test. In the acceptance test mode, SI PowerOn alarms can be
acknowledged with the Reset key.
- Alarm display.
Deselect the acceptance test, for example with the acceptance test wizard or wait until
completed (acceptance test time can be parameterized via MD
$MA_SAFE_ACCEPTANCE_TEST_TIMEOUT).
Alarm display showing cause of alarm disappears. No further operator action necessary.
Axis %1 SW limit switch deactivated
%1 = Axis number
Via the HMI, the SI acceptance test Safe limit position has been started, for example with
the acceptance test wizard. For these acceptance tests, the single-channel software limit
switches are deactivated for the axis/spindle, in order to assure that the safe limit posi-
tions can be approached.
- Alarm display.
Deactivation of the single-channel software limit switch for the displayed axis/spindle.
Deselect the acceptance test, for example with the acceptance test wizard, or wait until
completed.
Alarm display showing cause of alarm disappears. No further operator action necessary.
Axis %1 tolerance for safe standstill exceeded
%1 = Axis number
The axis has moved too far away from the setpoint position. It is further away than
allowed in MD SAFE_STANDSTILL_TOL.
The alarm can be reprogrammed in the MD
$MN_ALARM_REACTION_CHAN_NOREADY (channel not ready).
- Mode group not ready.
- Channel not ready.
- NC Start disable in this channel.
- Interface signals are set.
- Alarm display.
- NC Stop on alarm.
- Channel not ready.
Stop of the axis with the setpoint speed value=0 (STOP B). As soon as the actual speed
value is smaller than defined in MD $MA_SAFE_STANDSTILL_VELO_TOL, but the latest
after time-out in MD $MA_SAFE_PULSE_DISABLE_DELAY, the pulses will be sup-
pressed (STOP A).
Check the tolerance of zero speed monitoring: does the value match the precision and
control dynamics of the axis? If not, increase tolerance. If yes, check the machine for any
damage and rectify it.
Switch control OFF - ON.
Axis %1 safe velocity exceeded
%1 = Axis number
The axis has moved too quickly and faster than allowed in MD $MA_SAFE_VELO_LIMIT.
With active SBH/SG and a 1-encoder system, the velocity which corresponds to an
encoder limit frequency of 200 kHz has been exceeded.
