Accuracy of inverter terminal FM
I think that pulses output from the inverter terminal FM are detected by the output circuit switching command. Are the output pulses completely synchronized with the inverter output frequency?
For example, when a synchronous motor is driven by the inverter, can I use the output pulses from the terminal FM to detect the angle of rotation of the motor without a cumulative error?

Answer
The pulses output from the inverter terminal FM are not completely synchronized with the inverter output frequency.
The pulse circuit from the terminal FM and the inverter PWM modulation output circuit create signals separately. They are not completely linked with each other.
Therefore, when a synchronous motor is driven, the output pulses from the terminal FM cannot be used to detect the angle of rotation of the motor without a cumulative error.
