Overview of Alarms
- Interface signals are set.
- Alarm display.
- NC Stop on alarm.
- Channel not ready.
Remedy: Reduce the friction compensation gradient component MD 5460:
FRICTION_COMP_GRADIENT.
Program Con- Clear alarm with the RESET key in all channels. Restart part program.
tinuation:
310755
Axis %1 drive %2 area factor too high
Parameters: %1 = NC axis number
%2 = Drive number
Definitions: The positive area factor in drive MD 5462 AREA_FACTOR_POS_OUTPUT is too high or
the negative area factor in drive MD 5463 AREA_FACTOR_NEG_OUTPUT is too high.
Reactions: - NC not ready.
- The NC switches to follow-up mode.
- Channel not ready.
- NC Start disable in this channel.
- Interface signals are set.
- Alarm display.
- NC Stop on alarm.
- Channel not ready.
Remedy: Select a smaller value for the positive area factor in drive MD 5462
AREA_FACTOR_POS_OUTPUT or select a smaller value for the negative area factor in
drive MD 5463 AREA_FACTOR_NEG_OUTPUT.
Program Con- Clear alarm with the RESET key in all channels. Restart part program.
tinuation:
310756
Axis %1 drive %2 controlled system gain is less than or equal to zero
Parameters: %1 = NC axis number
%2 = Drive number
Definitions: The controlled system gain in drive MD 5435: CONTROLLED_SYSTEM_GAIN is less
than or equal to zero.
Reactions: - NC not ready.
- The NC switches to follow-up mode.
- Channel not ready.
- NC Start disable in this channel.
- Interface signals are set.
- Alarm display.
- NC Stop on alarm.
- Channel not ready.
Remedy: Enter a valid controlled system gain in drive MD 5435: CONTROLLED_SYSTEM_GAIN
(see model data calculations).
Program Con- Clear alarm with the RESET key in all channels. Restart part program.
tinuation:
310757
Axis %1 drive %2 blocking frequency > Shannon frequency
Parameters: %1 = NC axis number
%2 = Drive number
Definitions: The blocking frequency of a speed setpoint filter or manipulated variable filter is greater
than the Shannon sampling frequency from the sampling theorem.
