For standard motors: Reset the drive (delete the bootfile) and repeat the startup.
For third-party motors: One of the following machine data may contain an invalid value:
• Modify MD 1001: $MD_SPEEDCTRL_CYCLE_TIME (speed controller cycle),
• Modify MD 1134: $MD_MOTOR_NOMINAL_FREQUENCY (rated motor frequency),
• Modify MD 1138: $MD_ROTOR_COLD_RESISTANCE (cold rotor resistance),
• Modify MD 1139: $MD_STATOR_LEAKAGE_REACTANCE (Staenderstreureaktanz),
• Modify MD 1140: $MD_ROTOR_LEAKAGE_REACTANCE (rotor leakage reactance),
• Modify MD 1141: $MD_MAGNETIZING_REACTANCE (magnetizing reactance)
Fulfill the condition according to the folowing formula:
16 * P1001 * 0.00003125 * P1138 * 2PI * P1134 / (P1140 + P1141) < 1
