The default settings of low frequency optimization options of the synchronous motor
are suitable for most applications. If a larger torque is required at the low frequency, you
can enable the IF mode.

Bit setting = 0: when the inverter detects a fault corresponding to this bit, it will stop
the output and enter the fault status.
Bit setting = 1: when the inverter detects a fault corresponding to this bit, it will keep
the original status without protection.
This code is subject to bit operation. You only need to set the corresponding bit to 0 or
1. As shown in the table below:
