Axis %1 drive %2 generator mode: Motion at rotor position identification


%1 = NC axis number

%2 = Drive number


During the measurement, the motor has turned by more than the permissible value entered in MD1020: $MD_MAX_TURN_ROTORPOS_IDENT (maximum rotation of the rotor position identification). The rotation can be caused by switching on a rotating motor or by the identification itself.

The alarm can be reprogrammed in the MD ALARM_REACTION_CHAN_NOREADY (channel not ready).


-    Mode group 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.

Please inform the authorized personnel/service department.

If the rotation was caused by the identification itself, and if the error occurs repeatedly, then reduce MD1019: $MD_CURRENT_ROTORPOS_IDENT (rotor position identification current) or increase MD1020: $MD_MAX_TURN_ROTORPOS_IDENT (maximum rotation of the rotor position identification).

Rotor position identification with inductance: stall the motor during the identification

Rotor position identification with movement: check the factor load mass/load moment of inertia MD1076: $MD_FACTOR_MASS / $MD_FACTOR_INERTIA and increase if necessary.

Program Continuation:

Clear alarm with the RESET key in all channels of this mode group. Restart part program.
