ACT XXX LIM CRZ - What does it mean?

[737Andi 6]

Hi,

I noticed this message during my flight today and I was wondering what it meant?
It prevented me from climbing, cruising and descending faster than 230 kn although the TGT speed was set higher for CLB, CRZ and DES.

I suppose its an easy answer but I could not find anything on the internet.

Thank you very much!

Best regards Andi

Ok..I did some further tests and found out that the gear is causing the problem. I do however not know if its a software bug, misconfiguration of the hardware or a normal behaviour of the 737.

Gear Up = always 230kn limitation
Gear Down = 265 kn limitation
Gear in Locked "middle" Position = Desired speed

Is it normal that the plane is limited when the gear is in the full up position?

Thanks!
