Valid for built-in models of the brake unit.
When FC.00=0, the energy consumption braking is prohibited.
When FC.00=1, the energy consumption braking is allowed.
When FC.00=2, the energy consumption braking is allowed, and overvoltage stall
control is not performed during deceleration and stop.
FC.01 is used to adjust the duty cycle of the braking unit. If the braking utilization rate
is high, the braking unit action duty cycle is high and the braking effect is strong, but the
drive bus voltage fluctuates greatly during the braking process.
If the energy consumption braking gain FC.01 is 0, disable the energy consumption
braking function. The energy consumption braking voltage and voltage point are F7.21.
Note: The setting of this function shall consider the resistance and power of the
braking resistor.

AVR function

0: Do not act.
1: When the input voltage is higher than the rated value, it keeps acting.
2: When the input voltage is higher than the rated value, it only decelerates rather than
acts.
3: When the voltage is above 80% of the rated voltage, the AVR function is valid.
AVR is automatic voltage regulation.
When the input voltage deviates from the rated value, this function can keep the output
voltage constant, so generally the AVR shall operate, especially when the input voltage is
higher than the rated value.
When decelerating and stopping, the AVR does not act, the deceleration time is short,
but the running current is slightly larger; when the AVR acts all the time, the motor
