Overview of Alarms
• Positive quadrant: (MD 5481 + MD 5482) > (MD 5465 - 5466)
• Negative quadrant: (MD 5484 + MD 5482) > (MD 5468 - 5466)
Enter a valid combination in the above drive MD.
Program Con- Clear alarm with the RESET key in all channels. Restart part program.
tinuation:
310775
Axis %1 drive %2 knee area and saturation area of valve characteristic overlap
Parameters: %1 = NC axis number
%2 = Drive number
Definitions: The knee area and the saturation area of the valve characteristic overlap.
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 knee area and the saturation area overlap if:
• Positive quadrant: (MD 5465 + MD 5466) > MD 5486
• Negative quadrant: (MD 5468 + MD 5466) > MD 5488
Enter a valid combination in the above drive MD.
Program Con- Clear alarm with the RESET key in all channels. Restart part program.
tinuation:
311710
Axis %1 drive %2 resolution SSI motor measuring system invalid
Parameters: %1 = NC axis number
%2 = Drive number
Definitions: The configuration of the motor measuring system for an SSI encoder is incorrect:
MD_5022 $MD_ENC_ABS_RESOL_MOTOR must not be 0.
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: Set MD_5022 $MD_ENC_ABS_RESOL_MOTOR to correct value:
• Rotary encoder: Singleturn resolution (increments per revolution).
• Linear encoder: Resolution of an increment (in nanometers).
Program Con- Switch control OFF - ON.
tinuation:
311711
Axis %1 drive %2 transmission length SSI motor measuring system invalid
Parameters: %1 = NC axis number
%2 = Drive number
Definitions: The configuration of the motor measuring system for an SSI encoder is incorrect:
MD_5028 $MD_NO_TRANSMISSION_BITS (SSI frame length) is smaller than the num-
ber of all parameterized bits in MD_5021 $MD_ENC_ABS_TURNS_MOTOR (multiturn),
MD_5022 $MD_ENC_ABS_RESOL_MOTOR (singleturn) and MD_5027
$MD_ENC_CONFIG bit 14 (alarm bit) and MD_5027 $MD_ENC_CONFIG bit 12 (parity
bit).
