300784 Axis %1 drive %2 zero load voltage invalid
Parameters: %1 = NC axis number
%2 = Drive number
Definitions: 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).
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.
Channel not ready.
Remedy: 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.
Program Clear alarm with the RESET key in all channels. Restart part program.
Continuation:
300785 Axis %1 drive %2 zero load current less than or equal to zero
Parameters: %1 = NC axis number
%2 = Drive number
Definitions: The value in MD 1136: $MD_MOTOR_NOLOAD_CURRENT (motor no-load current) is less than or
equal to zero.
The alarm can be reprogrammed in the MD ALARM_REACTION_CHAN_NOREADY (channel not
ready).
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.
Channel not ready.
Remedy: Please inform the authorized personnel/service department.
- For standard motors: Reset the drive (delete the bootfile) and repeat the startup.
- For third-party motors: Check and, if necessary, refer to the motor data sheet to correct MD 1136:
$MD_MOTOR_NOLOAD_CURRENT (motor no-load current).
Program Clear alarm with the RESET key in all channels. Restart part program.
