300778 Illegal converter frequency rotor position identification Reset key
Power–up and cyclic
FDD only:
– Controllers are disabled, motor brakes
– SIMODRIVE_READY and DRIVE_READY are canceled.
When selecting the rotor position identification (MD 1018), only converter frequencies (MD 1100) of 4 kHz or 8 kHz
are permissible.
Change converter frequency or deselect rotor position identification.
Applies as from SW 6
300779 Motor moment of inertia x 0 Reset key
Power–up and cyclic
for MSD:
– Pulse suppression, motor coasts down
– SIMODRIVE_READY and DRIVE_READY are canceled
for FDD:
– Controllers are disabled, motor brakes
– SIMODRIVE_READY and DRIVE_READY are canceled.
Motor moment of inertia MD 1117 has a value that is smaller or equal to zero.
Enter a correct value in machine data MD 1117 ”Motor moment of inertia”.
Applies as from SW 6
300780 IO motor > I-rated motor Reset key
Power–up and cyclic
MSD only:
– Pulse suppression, motor coasts down
– SIMODRIVE_READY and DRIVE_READY are canceled.
The no–load current of the motor (MD 1136) is greater than the rated current (MD 1103) of the motor.
– Change motor data
– Save Boot drive
– Power up again
Applies as from SW 6
300781 IO motor > I-rated power section Reset key
Power–up and cyclic
MSD only:
– Pulse suppression, motor coasts down
– SIMODRIVE_READY and DRIVE_READY are canceled.
Because of its no–load current (MD 1136), the motor connected is too large for the power section used (continu-
ous current MD 1108).
Replace power section or motor
Applies as from SW 6
300782 Reactance x 0 Reset key
Power–up and cyclic
FDD only:
– Controllers are disabled, motor brakes
– SIMODRIVE_READY and DRIVE_READY are canceled.
Response configurable via MD 1613.0 as from drive SW 4.
The stator reactance MD 1139 or rotor reactance MD 1140 or main field reactance MD 1141 is smaller than or
equal to zero.
Correct error when entering MD 1139, MD 1140 or MD 1141.
Applies as from SW 6
