The alarm can be reprogrammed in the MD ALARM_REACTION_CHAN_NOREADY
(channel not ready).
Reactions: - 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.
Remedy: Please inform the authorized personnel/service department. The user must check the
cause and initiate the corresponding measures.
Program Con- Switch control OFF - ON.
tinuation:
300906
Axis %1 drive %2 safe braking ramp exceeded
Parameters: %1 = NC axis number
%2 = Drive number
Definitions: The drive is disabled via STOP A.
Request: In monitoring cycle.
The actual velocity of the axis has not been reduced during deceleration with "nset = 0"
(STOP B or STOP C) but has increased over the follow-on velocity limit during decelera-
tion and the tolerance entered in MD 1348: $MD_SAFE_VELO_TOL (actual velocity toler-
ance for SBR).
The alarm can be reprogrammed in the MD ALARM_REACTION_CHAN_NOREADY
(channel not ready).
Reactions: - 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.
Remedy: Please inform the authorized personnel/service department. Check the deceleration
behavior and, if necessary, modify the velocity tolerance in MD 1348:
$MD_SAFE_VELO_TOL. Restart is only possible with POWER ON.
Program Con- Switch control OFF - ON.
tinuation:
300907
Axis %1 drive %2 tolerance for safe operational stop exceeded
Parameters: %1 = Axis number
%2 = Drive number
Definitions: The drive is disabled via STOP A or STOP B. This blocks the pulses over the relay
"Antrieb_IMP".
Request: In monitoring cycle.
The actual position has moved too far away from the setpoint/zero position (outside the
zero speed window). The zero speed window is parameterized through MD 1330:
$MD_SAFE_STANDSTILL_TOL (safe operational stop standstill tolerance).
Reactions: - Mode group not ready.
- Channel not ready.
- NC Start disable in this channel.
- Interface signals are set.
