F5 KEB inverter nop problem

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.

I have a KEB combivert F5. The parameter ru 00 shows nop even if i give switching to terminal 16 for control release.Please help.


This may be due to the inverter waiting for an ST signal via buss communications.

What is the part # of the unit in question?

The inverter is recognizing that terminal 16 is going active but still waiting for another command to enable the inverter.
