Overview of Alarms
Remedy: This message disappears automatically when the test is finished.
Program Con- Alarm display showing cause of alarm disappears. No further operator action necessary.
tinuation:
301701
Axis %1 drive %2 limit value for safe velocity too large
Parameters: %1 = Axis number
%2 = Drive number
Definitions: Booting has been interrupted. The pulses remain disabled.
Request: In monitoring cycle.
The limit value of the safe velocity exceeds the velocity corresponding to a limit frequency
of 200 kHz (300 kHz for 840D with SW4.2 and higher and for 840C with SW6.1 and
higher).
The max. permissible speed that can be monitored is determined as follows:
nmax[rev/min] = (200000[Hz] * 60) / encoder marks value
Monitoring condition:
Modify MD 1331: $MD_SAFE_VELO_LIMIT[n] <= (1 / ue) * nmax
Reactions: - Mode group not ready.
- 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. Check the entry in the
machine data MD 1331: $MD_SAFE_VELO_LIMIT[n] (safe velocity limit values) correct, if
necessary, and perform POWER ON.
Program Con- Switch control OFF - ON.
tinuation:
301702
Axis %1 drive %2 track inversion incorrect
Parameters: %1 = NC axis number
%2 = Drive number
Definitions: With rotary spindles without EnDat interface operating with enhanced controller modules,
the track inversion (MD_1011.0=1) must not be switched on. Otherwise this error is trig-
gered.
Modify MD 1011: $MD_ACTUAL_VALUE_CONFIG (actual value sensing configuration
IM)
Reactions: - Mode group not ready.
- 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. With rotary spindles without
EnDat interface operating with enhanced controller modules, the track inversion must be
performed by soldering the A and B tracks differently: A <-> B and A* <-> B*
Program Con- Switch control OFF - ON.
tinuation:
301703
Axis %1 drive %2 encoder/motor type are not compatible
Parameters: %1 = NC axis number
%2 = Drive number
