2.1.5 Basic commissioning
Complete the basic commissioning as follows before the actual use of the VFD:
1. Autotuning. If possible, de-coupled from the motor load to start dynamic
autotuning. Or if not, static autotuning is available.
2. Adjust the ACC/DEC time according to the actual running of the load.
3. Commissioning the device via jogging and check that the rotation direction is as
required. If not, change the rotation direction by changing the wiring of motor.
4. Set all control parameters and then operate.
