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 the protection corresponding to this bit, it will
stop the output and enter the protection status.
Bit setting = 1: when the inverter detects the protection 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.
