You may be getting unstable speed because it is unloaded. Try in vector control P100=3 to give you better speed control. |

How are you measuring the speed?Howmuch variation are you seeing? |

Hi Amit3545, As IBN-Service stated, you absolutely cannot make sense of drive output multimeter readings at most speeds, but even worse for low speeds. You definately need an ascilloscope here - then you can see the exact voltage output. If the motor is unstable, please confirm the motor is good by performing an insulation resistance measurement on the motor. If this is ok, I would recommend creating a backup of your drive parameters and then factory default the drive and start the basic commissioning with the simplest setup (This ensures no unexpected parameterisations are present) as follows: Enter your motor data correctly (Check for wiring configuration) P554=5 P573=8 P574=9 P443=58 Regards, Graeme
