300783 Rotor resistance invalid Reset key
Power–up and cyclic
MSD only:
– Pulse suppression, motor coasts down
– SIMODRIVE_READY and DRIVE_READY are canceled.
The rotor resistance is less than or equal to zero or a format overflow has occurred.
The following machine data may have an incorrect value:
– Speed controller cycle MD 1001
– Motor rated frequency MD 1134
– Rotor resistance cold MD 1138
– Stator leakage reactance MD 1139
– Rotor leakage reactance MD 1140.
Applies as from SW 6
300784 Motor no-load voltage invalid Reset key
Power–up and cyclic
MSD only:
– Pulse suppression, motor coasts down
– SIMODRIVE_READY and DRIVE_READY are canceled.
Error in no–load voltage (MD 1135):
– MD 1135 x 0 or
– MD 1135 > MD 1132 or
– MD 1135 x MD 1142 / MD 1400 + Vpre>450 V
With
Vpre=0.181 x MD 1136 x MD 1142 x MD 1119
MD 1132: Rated motor voltage
MD 1400: Rated motor speed
MD 1142: Threshold speed field weakening
MD 1136: No–load motor current
MD 1119: Inductance series reactor
Correct error when entering
– Rated motor voltage MD 1132 or:
– No–load motor voltage MD 1135 or
– Rated motor speed MD 1400 or
– Rotor resistance cold MD 1138
– Threshold speed field weakening MD 1142 or
– No–load motor current MD 1136.
Applies as from SW 6
300785 Motor no-load current x 0 Reset key
Power–up and cyclic
MSD only:
– Pulse suppression, motor coasts down
– SIMODRIVE_READY and DRIVE_READY are canceled.
Motor no–load current MD 1136 is smaller than or equal to zero.
Correct the error when entering the motor no–load current MD 1136.
Applies as from SW 6
