        @change: From 315.2.0 onward, following arguments are dropped and can be set by
                 self.seq_svc.setWrenches instead of this method.
                 See an example at https://github.com/fkanehiro/hrpsys-base/pull/434/files#diff-6204f002204dd9ae80f203901f155fa9R44:

                 - ref_force[fx, fy, fz] (unit: N) and ref_moment[tx, ty, tz] (unit: Nm) can be set via self.seq_svc.setWrenches. For example:

                   self.seq_svc.setWrenches([0, 0, 0, 0, 0, 0,
                                             fx, fy, fz, tx, ty, tz,

                                             0, 0, 0, 0, 0, 0,])

                   setWrenches takes 6 values per sensor, so the robot in the example above has 4 sensors where each line represents a sensor.
