Linear force ramp increments in ABF

Good day,

During an ABF run, I understand that once the minimum number of samples has been achieved for a given bin the biasing forces are added following a linear ramp. During this ramp is the force applied in discrete increments of a fixed value per time-step or does the applied quantity vary? If so, what is this increment or is there a procedure to determine how much force is added per step in the linear ramp?

Many thanks for the support.
