Overview of Alarms
Remedy: Enter a smaller value for the D component of the force controller MD 5246:
FORCECTRL_DIFF_TIME.
Program Con- Clear alarm with the RESET key in all channels. Restart part program.
tinuation:
310764
Axis %1 drive %2 controlled system gain for force controller is less than or equal to
zero
Parameters: %1 = NC axis number
%2 = Drive number
Definitions: The controlled system gain for the force controller in drive MD 5240
FORCECONTROLLED_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: Set a valid controlled system gain in drive MD 5240
FORCECONTROLLED_SYSTEM_GAIN (see model data calculations).
Program Con- Clear alarm with the RESET key in all channels. Restart part program.
tinuation:
310771
Axis %1 drive %2 gain in fine area of valve characteristic is less than or equal to
zero
Parameters: %1 = NC axis number
%2 = Drive number
Definitions: The gradient in the fine area of the valve characteristic 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: The gradient in the fine area is calculated as follows:
• Positive quadrant: (MD 5464 - MD 5480) / (MD 5465 -5481)
• Negative quadrant: (MD 5467 - MD 5483) / (MD 5468 - 5484)
Enter a valid combination in the above drive MD.
Program Con- Clear alarm with the RESET key in all channels. Restart part program.
tinuation:
310772
Axis %1 drive %2 gain in rough area of valve characteristic is less than or equal to
zero
Parameters: %1 = NC axis number
%2 = Drive number
Definitions: The gradient in the coarse area of the valve characteristic is less than or equal to zero.
Reactions: - NC not ready.
- The NC switches to follow-up mode.
