- NC not ready.
- Channel not ready.
- NC Stop on alarm.
- NC Start disable in this channel.
- The NC switches to follow-up mode.
- Alarm display.
- Interface signals are set.
Please inform the authorized personnel/service department. Check the configuration of
the direct measuring system. See NC-MD 30220: $MA_ENC_MODULE_NR and NC-MD
30230: $MA_ENC_INPUT_NR.
Switch control OFF - ON.
Axis %1 drive %2 measuring system used several times
%1 = NC axis number
%2 = Drive number
The NC has assigned the direct measuring system to a measuring system output which is
already used by another direct measuring system. This error can only occur with the
810D!
- NC not ready.

Switch control OFF - ON.
Axis %1 drive %2 asynchronous mode: feedforward control gain out of range
%1 = NC axis number
%2 = Drive number
If motor inertia and motor nominal torque have been selected unfavorably, the asynchro-
nous motor feedforward control gain is beyond the range of the internal number format.

Please inform the authorized personnel/service department.
• Operation without encoder: Reduce the number of encoder lines in MD 1005:
$MD_ENC_RESOL_MOTOR (encoder resolution for motor measuring system), since
this has an impact on the internal number format. Optional/additional measure: see
operation with encoder
• Operation with encoder: Reduce speed controller cycle MD 1001:
$MD_SPEEDCTRL_CYCLE_TIME (speed controller cycle).
Switch control OFF - ON.
