Possibly on a CNC turret punch you need to hold the work when the punch comes down, but otherwise, locking the axis every time it stops moving causes a discontinuity in the servo drive. In some cases it could cause the drive to go into current limit and fault while locked, depending on drift and stiffness of the servo amp. When the brake is released, the drive would suddenly jump.
