: 想请问各位下面这个例子
: A servomotor with an AB phase per second (PPS) is used in a X-Y table.
: Usually, the resolution of encoder is 2000 counts per phase.
: The maximum rotation speed of motor is designed to be 3600 RPM.
: The maximum pulse command output frequency can be acquired below:
: MaxVel = 3600/60 * 2000 * 4 = 480,000 PPS
: 请问位舍答案是480,000 PPS
: 不懂为什麽要乘以4 @@"...
: 请各位解解迷津
: 感谢....
: 麻烦各位了
