Double closed loop control is implemented with increment encoder through signal of speed and position.
采用增量式编码器，通过速度及位置信号进行双闭环控制。
The first parameter can be confirm according to the specification, then the second parameter can be calculated according to the concessional increment (downgrade) or decrease (upgrade) of speed.
第一项参数按规定确定，然后根据容许速度降低(上坡)或增加值(下坡)计算第二项参数。
Because of limitation of computer software running speed, CNC system using reference-pulse interpolation algorithm have low least input increment and rapid feed velocity.
由于计算机软件运算速度的限制，使用脉冲增量插补算法所得到的数控机床进给运动的精度和速度都比较低。
