7.6 Parameters of the motor

  • Physical accident may occur if the motor starts up suddenly during autotune. Please check the safety of surrounding environment of the motor and the load before autotune.

  • The power is still applied even the motor stops running during static autotune. Please do not touch the motor until the autotune is completed, otherwise there would be electric shock.

  • Do not carry out the rotation autotune if the motor is coupled with the load, please do not operate on the rotation autotune. Otherwise, misacts or damage may occur to the VFD or the mechanical devices. When carry out autotune on the motor which is coupled with load, the motor parameter won’t be counted correctly and misacts may occur. It is proper to de-couple the motor from the load during autotune when necessary.

Goodrive310-UL series VFDs can drive both asynchronous motors and synchronous motors. And at the same time, they can support two sets of motor parameters which can shift between two motors through multi-function digital input terminal or communication.

The control performance of the VFD is based on the established accurate motor model. The user has to carry out the motor autotune before first running (take motor 1 as the example).

Note:

1. Set the motor parameters according to the name plate of the motor.

2. During the motor autotune, de-couple the motor from the load if rotation autotune is selected to make the motor is in a static and empty state, otherwise the result of autotune is incorrect. The asynchronous motors can autotune the parameters of P02.06–P02.10, while the synchronous motors can autotune the parameters of P02.20–P02.23.

3. During the motor autotune, do not to de-couple the motor from the load if static autotune is selected. Because only some parameters of the motor are involved, the control performance is not as better as the rotation autotune. The asynchronous motors can autotune the parameters of P02.06–P02.10, while the synchronous motors can autotune the parameters of P02.20–P02.22. P02.23 (synchronous motor 1 counter-electromotive force constant) can be counted to attain.

4. Motor autotune only involves the current motor. Switch the motor through P08.31 to carry out the autotune on the other motor.
