1 Percent speed is percent of maximum test speed.
2 Advance from one mode to the next within a 20-second transition phase. During the transition phase, command a linear progression from the torque setting of the current mode to the torque setting of the next mode.
3 Percent torque is percent of maximum torque at the commanded test speed.
