No, they cannot be monitored when Pr.363 is other than "5". They are enabled only when Pr.363 = 5.

Until now the DC has been applied to perform the frequency search. When Pr.162 = 3 or 13, the impact is reduced by detec

When the value is written to Pr.646 (Stored winding diameter), the stored value is used. When the value is not written,

A separate power supply is required according to the encoder power supply specification.

The 800 series supports the multiple rating. Thus, the rated current of the corresponding motor is 40% or higher of the

The inrush current limit circuit is not built in the FR-A842 (inverter unit). It is built in the FR-CC2 (converter unit)

When the online auto tuning (magnetic field observer) is enabled, the monitoring accuracy is ± 10%.

Since the lower limit has been internally set, the setting value of 3 % or less is recognized as 3%.

The error indicates that the parameter setting of the PLC function is not set. It is considered that the PC parameter is
