Hi I am using thanos's board 2.2kw vfd 3 phase 50hz 2 pole 400v ac motor 1.5hp
when the arm wants to go back to start position, the board lowers the voltage (10-0) until it gets close to its position.
when its very close, the voltage speed is 0.6v to the vfd. so it sends 3 hz to the motor and the motor doesnt spin anymore. the problem is that the arm doesnt return correctly to the start position but is slightly tilted. for now only the gear reduction and arm are connected. no load
can i live with it ? do i need to change to 4 pole motor ?

gear ratio is 100 to 1 i think i should change to something like 33 to 1 for more speed
