Hi:

6se70problem confront me. I set P100=4 ,start the inverter , kk148 no speed value measured and F015 displayed ; set P100=3 ,start the inverter, run properly , KK148 have the feedback speed . I changed the CUVC card ,changed the encoder , it’s same .

Hi

In Masterdrive compendium wrote (page 132) : 3: Vector control without tachometer (f-control)
4: Vector control with tachometer (n-speed) with pulse encoder (P130 = 11);

And if you see down in manual page 157 and page 159 how is receive this signal on KK148. In case of P100=4 needs motor encoder. And of course receive this fault F15 (Motor stall).
F15. One of the reason is: With speed control (P100 = 4) and masterdrive (see P587), the fault can also point to an interruption in the encoder cable. This case has the same significance as if the drive is locked.
