Position restrain in ABF

Hi all,

I was using ABF for PMF calculation. But during simulation run my protein
and membrane is moving a bit in z direction. Will it effect PMF estimate?
For future reference should I restrain some atoms to avoid this behaviour?
 Looking forward for your suggestions.
Thanks in advance.
