through the braking resistor to make the
bus voltage drop.
2. The energy consumption braking duty
cycle 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.
Note: The setting of this function shall
consider the resistance and power of
the braking resistor. Be sure to set the
function parameters correctly
according to the actual use.
FC.02
AVR
function
0: No action
1: Act always
2: Do not act only during deceleration
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.
Note: 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 decelerates
smoothly and the running current is
small, but the deceleration time
becomes longer.

operation
0: No action
1: Action
During the no-load or light-load
operation, the motor detects the load
current and adjusts the output voltage
appropriately to achieve the purpose of
energy saving.
