1) Register Details
This is the configuration register for detection threshold when outputting PF signal.
The PF detection threshold value is specified by signed 16-bit integer as "%" with PV reference value or CC reference
value as 100%.
The PF signal detection target is selected by the "PF mode setting register".
Configuration data is retained even when input is cut off.

*An exception response (Exception code: 0x03) is returned when writing values outside the range.
The PF detection threshold is compared with the detection target, and when the target falls below the threshold value, the
PF signal is output.
The detection target is selected by [# 14 PF mode] register setting and the target is output voltage or output current.
PF signal update cycle is every 1 ms.
The output display LED of the power supply unit turn off in synchronization with the PF signal output.
In order to prevent signal fluttering, it is possible to set the confirmation time limit by setting the [# 15 PF count] register.
Also, when a voltage is applied to the output terminal of the power supply from the outside, if the PF threshold is exceeded,
the PF signal will be canceled, but not in sleep mode.
For details, Refer to the instruction manual.
