Axis %1 drive %2 zero load voltage invalid

%1 = NC axis number

%2 = Drive number

Error in the no-load voltage (MD 1135):

MD 1135 <= 0 or

MD 1135 > MD 1132 or

MD 1135 x MD 1142/MD 1400 + Uvor > 450V.

Where

Uvor = 0.181 x MD 1136 x MD 1142 x MD 1119

Modify MD 1135: $MD_MOTOR_NOLOAD_VOLTAGE (motor no-load voltage)

Modify MD 1132: $MD_MOTOR_NOMINAL_VOLTAGE (rated motor voltage)

Modify MD 1400: $MD_MOTOR_RATED_SPEED (rated motor speed)

Modify MD 1142: $MD_FIELD_WEAKENING_SPEED (threshold speed for field weakening)

Modify MD 1136: $MD_MOTOR_NOLOAD_CURRENT (motor no-load current)

Modify MD 1119: $MD_SERIES_INDUCTANCE (series reactor inductance)

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

-    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.

-    Channel not ready.

Please inform authorized personnel / the service department.

For standard motors: Execute a general drive reset (delete the boot file) and repeat the startup.

For non-Siemens motors: Check and, if necessary, correct the following machine data with reference to the data sheet:

Modify MD 1132: $MD_MOTOR_NOMINAL_VOLTAGE (nominal motor voltage)

Modify MD 1135: $MD_MOTOR_NOLOAD_VOLTAGE (motor no-load voltage)

Modify MD 1400: $MD_MOTOR_RATED_SPEED (rated motor speed)

Modify MD 1142: $MD_FIELD_WEAKENING_SPEED (threshold speed for field weakening)

Modify MD 1136: $MD_MOTOR_NOLOAD_CURRENT (motor no-load current).

Call SIEMENS AG, SIMODRIVE Hotline.

Clear alarm with the RESET key in all channels. Restart part program.
