The function codes F01.19 to F01.23 are the parameters of the synchronous motor. They
are usually unavailable to users. Please get them through motor parameter
self-identification (F01.34).
Before the motor parameter self-identification, be sure to set F01.00 to F01.08
correctly according to the actual situation. In particular, select the motor type (F01.00=2)
correctly.
