Question about Inverter KEB COMBIVERT F5
I have a KEB F5 combivert 1.5KW VFd. The problem is that even after connecting the ST terminal the display is showing "nop" when it must be showing "LS", due to which the vfd is not running. I have checked the parameters but still could not find the problem. Please help
If using bus communications (Can, ProFi, Mod, ext), there may be a communications command (Software signal) that is not being provided. Hardware and software enable signal required to obtain LS.
Possible that the terminal on the control card is bad due to miss connection or signals outside of the rated value.
