DLSHBL for monitoring rate of change of frequency

I want to use load relay model DLSHBL only for plotting bus frequency derivative stored in VAR(L+4). I don't want to define any CONS since I am only interested in the bus frequency derivative. Is this possible? I have tried it, but the plot shows zero bus derivative frequency after any disturbance.
