Fault reset
Reset fault / trip condition on transition from 0 to 1
Reference rotational speed. Unit: [RPM]/[0.1 Hz]/[0.01 Hz].
If Motor poles setting for RPM (inverter parameter P049 is set to
zero, the Unit depends on the inverter mode (d060):
d060 = 2 (High Frequency mode): Unit is [0.1 Hz]
d060 != 2 (High Frequency mode): Unit is [0.01 Hz]
