Chapter 7 Detailed Explanations of Functional Parameters
Start frequency is the initial frequency when inverter starts. For
device with heavy load or requires large starting torque, increasing
start frequency can make start easier. However, if the start
frequency is too high, it may cause over current protection.

Stop frequency setting Initial value : 0.5Hz
Setting range
0.10-10.00Hz
Unit
0.01Hz
When inverter receives stop command, it reduce the output
frequency until the stop frequency, then it will start coasting stop or
DC injection brake stop according to the setting.

Dc braking in start is application for fan in stop mode and moving
load. Because before inverter starts, motor is in free running mode
