brake of high-inertia load or the situations that require quick stop. In such a case, it is necessary to
select appropriate dynamic brake resistor and break unit. The AC drives equal and below 30kW is
provided with a standard built-in brake unit. Built-in brake unit is optional for AC drive 37kW
～
75kW.

F02.18
Dynamic brake threshold
voltage
Range:90.0
～
150.0%
Default:128.0%
This parameter takes effect only to the drives with built-in brake unit.
When bus voltage of AC drive attains the value of F02.18, dynamic brake shall perform. The
energy shall be rapidly consumed through brake resistor. This value is used to regulate the brake
effect of brake unit.
F02.19
Brake use ratio
Range:5.0
～
100.0%
Default:100.0%
It is valid only for the AC drive with internal braking unit and used to adjust the duty ratio of the
braking unit. The larger the value of this parameter is, the better the braking result will be. However,
too larger value causes great fluctuation of the AC drive bus voltage during the braking process.

Accel time means required time for drive to Accelerate to maximum frequency F01.08 from zero
frequency, while Decel time refers to the time required for drive to Decelerate to zero frequency from
maximum frequency F01.08.
These four types of Accel/Decel time can be selected through the ON/OFF combination of
DI terminals" Accel/Decel time determinant 1" and "Accel/Decel time determinant 2". See the following
table.
