SEW Motors New DRS Motors

Hi Wasaadeh:

You might want to follow this link and take a look at the various motor specs. from SEW Eurodrives.

I wish I could help you better, but I haven't worked with these motors.

You may have already done this but check ALL the parameters programmed into the VFD and ensure that they match your new motors nameplate values make sure you set/check all the parameters your-self don't use a set-up wizard or anything, certain things may have changed with the new motor, ie. nominal frequency, power factor etc.

Other than that I would contact my SEW Euro-drive Rep.

Hope you get it figured out.

I already sent a mail to SEW, with no response yet, just wanted to find out if anybody else is experiencing the same issue.

I just went through all the parameters manually on the inverter without the software, all seems to be configured correctly, still i'm getting high currents i,e:

at 60HZ i get 0.9 A for (motor power 0.75KW, 400V, 1.9A, 60Hz)

at 20HZ i get 1.8 A

at 15 HZ i get 2.1 A

and the motor is running without any load.

Thank you for your replies,
