Hello. I have a drive (vfd) type keb f4, which unfortunately has a technical problem. The drive accepts all the commands and when the command is given, the frequency of the drive starts to increase, but no voltage appears at the output of the drive. please guide me.
hi Please . How can I increase the motor speed by parameters? Having trouble increasing the motor speed by more than 40 the motor speed varies and moves randomly? What do you think is the solution?
I would like to inform you that we have been suffering from the problem of 88888 alarm Displayed and keypad not work for a long time. We have almost all the KEB F5 inverter. What can we do to solve this problem? Please help
