hi all i used seweurodrive motors +inverter when start motors + inverter all it is ok .when activate thanos board nouse from engine (sound) .i am try setup hz in inverter nothing changed. WHEN PLAY GAME IT IS ENGINE QUIET youtu.be/xqGeTcTxcBAthanks michal

What is your wiring from the vfd to the motor? Delta or Star?
It also sounds like you need to calibrate the motor settings inside the vfd, to set correct motor parameters.
Thanks Thanos

hi Thanos conection it is delta. witch one parameters need setup in vfd ? (http://download.sew-eurodrive.com/download/pdf/16810813.pdf) VFD setup like this youtu.be/0zRaP2Q5FtE secon video youtu.be/Oru9g_0KMfY thanks Michal

Hi,
Try connecting the motors in STAR. I remember I had the same noise issues with some motors because we're not designed for delta connection.
Also try using braking resistors as they will absorb any extra current and help with the EMI noise.
Thanks Thanos

hi Thanos Thanos connection star or delta same problem when set up in board PID setup set kp<P> 10 engine are silent. setup over 10.. engine noise Edit: PID -<P> 10 or 25 Nothing changes

are you sure this isnt a PID tuning issue?
Once P is over 10 then the setpoint is being missed? the noise is because the motor is trying to reach setpoint?
Edit: ok from the video probably not.

Hi Michal, We discussed I remember for this point .Did you try to change the pwm frequency ( don't remember which parameter number it is , will have a look) , the normal setup is 4kHz , you can try to increase it to 8 ,12 or 16 kHz. So high is this pwm frequency so quiet are the motors. And when you use the movitools software to start to setup the motors and inverter , there is a simply way to configure the motors.As the motor is also a sew motor you can choose the right motor parameters when you choose it in the list of motors. Just have a look to this'video below : look around 1min 30 s , this is the place where you can choose the motor specification according the motor plate . youtu.be/0zRaP2Q5FtECould you take a picture from the plate on motor I will have a look to the motors specification.This plate is on the motor. Cheers

Hi vicpopo 1. pwm frequency setup 16khz (Nothing has changed) 2. setup in movitools all correct ,engine(setup mine engine), ramp.... like in video. Nothing has changed edit: reset VFD Nothing has changed

hi all stil try ... when setup on board (minimu sped motor----- 1 ) and (oversample ADC---- 1 motor) silent only play couple minutes engine very hot and vfd to same it is ok ? thanks Michal
