在sinamic s120中的P1755具体含义
p1755[0...n] Motor model changeover speed sensorless operation / MotMod n_chgSnsorl
Des cription: Sets the speed to change over the motor model to sensorless operation (without encoder).
Notice: The changeover speed represents the steady-state minimum speed up to which the motor model can be used
in steady-state operation without encoder (sensorless operation).
If the stability is not adequate close to the changeover speed, it may make sense to increase the parameter value.The changeover speed applies for the changeover between open-loop and closed-loop control mode.
我想问的是：
在changeover speed 下是U/F控制么？
在changeover speed 的转矩是什么那？
