Feed rate not working

Hi All

I have 2 machines with the same Heid 426 controls . When I run the below code on one it works fine the other machine it will not move at
line (2038 L IX+0.15 IY+0.15) for some reason on the second machine its not picking up the last feed rate F40 , If I put a feed on the line it works ok Can any one tell me if there is a parameter I can change so that both controls are acting the same.
