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.
Reaction: 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 Clear alarm with the RESET key in all channels. Restart part program.
Continuation:
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.
Reaction: 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 Switch control OFF - ON.
