SIMODRIVE 611 universal Description of Functions (FBU) – 04.05 Edition
784 No-load voltage, motor \%d invalid
Cause Error in no-load voltage P1135:
– P1135 <= 0 or
– P1135 > P1132 or
– P1135 * P1142 / P1400 + Vser.react. > 450V.
With Vser.react. = 0.181 * P1136 * P1142 * P1119
Remedy Determine the no-load voltage of the installed motor and enter this in
P1135.
Third-party motor:
The following parameters may have incorrect values:
P1119 (inductance of the series reactor)
P1132 (rated motor voltage)
P1135 (no-load motor voltage)
P1400 (rated motor speed)
P1142 (threshold speed for field weakening)
P1136 (no-load motor current)
Check parameters and if required correct using a motor data sheet.
Siemens motor:
The no-load voltage is determined from the motor code (P1102).
Acknowledgement RESET FAULT MEMORY
Stop response STOP II (SRM, SLM) STOP I (ARM)
785 No-load current, motor \%d invalid
Cause The no-load current (P1136) of the motor (ARM) is incorrect (less than/
equal to zero).
Remedy Determine the no-load current of the motor used (ARM) and enter into
P1136.
Third-party motor:
The no-load current should be determined from a motor data sheet.
Siemens motor:
The no-load current is determined from the motor code (P1102).
Acknowledgement RESET FAULT MEMORY
Stop response STOP II (SRM, SLM) STOP I (ARM)
786 Field-weakening speed, motor \%d invalid
Cause The threshold speed for field weakening for induction motors (P1142) is
incorrect (less than/equal to zero).
Remedy Determine the threshold speed for field weakening for the motor used
and enter in P1142.
Third-party motor:
The field weakening speed should be determined from a motor data
sheet.
Siemens motor:
The field weakening speed is determined from the motor code (P1102).
