DC Brake at Start-up is used for loads that may move before the AC drive starts, such as fans and
pumps. Under such circumstances, DC Brake can be used to hold the load in position before
setting it in motion.
DC Brake at stop is used to shorten the stopping time and also to hold a stopped load in position,
such as crane or cutting machine.

Voltage Incrasing Gain
Factory Setting: 100
Settings 1~200%
When the user is using speed tracking, adjut Pr07-05 to slow down the increasing of voltage if
there are errors such as oL or ocv. Then the speed tracking time will be longer and the Pr07-09
Pivot Point of the Speed Tracking of the Current 20~200%, factory setting 50. If the pivot point of
the user is higher than the Pr06-03 pivot point of the oc stall, then the drive will choose the pivot
point of Pr06-03 as the highest pivot point of the speed tracking.
Restart after Momentary Power Loss
Factory Setting: 0
Settings 0: No function
1: Speed search for last frequency command
2: Speed search for the minimum output frequency
This parameter determines the operation mode when the AC motor drive restarts from a
momentary power loss.
The power connected to the drive may power off momentarily due to many reasons. This function
allows the drive to keep outputting after power is on again after power off and won’t cause drive
stops.
Setting 1: Operation continues after momentary power loss, speed search starts with the Master
Frequency reference value after drive output frequency and motor rotator speed is synchronous.
The motor has the characteristics of big inertia and small obstruction. For example, in the
