For standard motors: Reset the drive (delete the bootfile) and repeat the startup.
For third-party motors: Enter a valid value in drive MD 1113:
$MD_TORQUE_CURRENT_RATIO (torque constant), or check and, if necessary, correct
the ratio of MD1113: $MD_TORQUE_CURRENT_RATIO (torque constant) / MD1112:
$MD_NUM_POLE_PAIRS (motor pole pairs).
Switch control OFF - ON.
Axis %1 drive %2 motor moment of inertia less than or equal to zero
%1 = NC axis number
%2 = Drive number
