Axis %1 drive %2 zero load current > rated current of power section
%1 = NC axis number
%2 = Drive number
On the basis of its no-load current (MD 1136: $MD_MOTOR_NOLOAD_CURRENT
(motor no-load current), the connected motor is too large for the power section in use
(continuous thermal current MD 1108: $MD_INVERTER_MAX_THERMAL_CORR (cur-
rent limit for power section).
The alarm can be reprogrammed in the MD ALARM_REACTION_CHAN_NOREADY

2. Check the configuration and install a suitable power section for the motor. Repeat the
startup.
Clear alarm with the RESET key in all channels. Restart part program.
Axis %1 drive %2 reactance less than or equal to zero
%1 = NC axis number

The value in MD 1139: $MD_STATOR_LEAKAGE_REACTANCE (stator leakage reac-
tance) 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.
The alarm can be reprogrammed in the MD ALARM_REACTION_CHAN_NOREADY
