液压特性FB520说明书中这么说的：

"Not until the cam disk of the compensation characteristic is reloaded, it is

permanently available in the load memory of the technology CPU so that it can

be used at the next start of the CPU again."

"The compensation characteristic of the hydraulic axis can be newly determined and

activated at any point in time. For this purpose, the characteristic does not have to

be stored in the STEP 7 project; instead, it can always be determined locally at the

machine."

意思是写进去之后就一直在那，关键是我写的是错误的，一使能液压轴就报错，有什么办法把写进去的清除掉呢？新的又写不了了，一直报错。
