If the YASKAWA Controller experiences overvoltage trips during acceleration, deceleration, or sudden speed/load changes, gradually increase the setting by 50 ms. However, if the response is slow, gradually reduce this setting by 10 ms.
What to do if YASKAWA FSDrive-MV1000 has poor torque at low speeds?
For poor motor torque at low speeds with your YASKAWA Controller, increase the setting if the torque is insufficient at speeds below 10 Hz. If the motor exhibits excessive instability at start-up, reduce the setting.
How to improve YASKAWA FSDrive-MV1000 torque below 10 Hz?
If you are experiencing poor motor torque at speeds below 10 Hz with your YASKAWA Controller, increase the setting if the torque is insufficient. If motor hunting and oscillation occur with a relatively light load, decrease the setting.
How to improve speed precision on YASKAWA FSDrive-MV1000 Controller?
To improve poor speed precision on your YASKAWA Controller, after setting the motor-rated current (E2-01), motor-rated slip (E2-02), and motor no-load current (E2-03), adjust the slip compensation gain (C3-01).
