转换器操作的特性 - 电机1PS0，1PS1，
1PS5 and 1MD5
Limits for example control ranges are listed in the power tables
on the following pages. For individual drive checks, the following
configuration characteristics apply to frame sizes 71 to 200 and
225到355。
For driven machine power or torque less than or equal to rated
