300727 Axis %1 drive %2 reactance less than or equal to zero
Parameters: %1 = NC axis number
%2 = Drive number
Definitions: The value in MD 1139: $MD_STATOR_LEAKAGE_REACTANCE (stator leakage reactance) or MD
1140: $MD_ROTOR_LEAKAGE_REACTANCE (rotor leakage reactance) or MD 1141:
$MD_MAGNETIZING_REACTANCE (magnetizing reactance) is less than or equal to zero.
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.
Remedy: Please inform the authorized personnel/service department.
For standard motors: Reset the drive (delete the bootfile) and repeat the startup.

Program Switch control OFF - ON.
Continuation:
300728 Axis %1 drive %2 adaption factor torque/current too high
Parameters: %1 = NC axis number
%2 = Drive number
Definitions: The matching factor from setpoint torque to cross current in the speed controller is too large.
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.
Remedy: Please inform the authorized personnel/service department.
For standard motors: Reset the drive (delete the bootfile) and repeat the startup.
