Furthermore, they say, it is the best way for researchers to gather the range of observations that are necessary to speed up discoveries or to identify large-scale trends.
Direct control of torque over the motor speedrange is provided by the drive, which helps the motor and drive generate torque levels high enough to cycle the press back to ready position.
直接控制扭矩而不是电机转速范围，可以使得电机和变频器产生足够高的扭矩使得压机可以回复到原来的位置。

This speedrange was chosen because it is when most collisions take place, especially rear-end shunts in slow-moving traffic.
