1-2..Safety precautions
Safety precautions in this manual are divided into the following two categories:
Danger: the dangers caused by failure to perform required operation, may result in
serious injury or even death;
Caution:the dangers caused by failure to perform required operation, may result in
moderate injury or minor injury, and equipment damage;
Process
Type
Dangerous
● Only well-trained personnel are allowed to use this unit.
● Fix the screw when connecting, or the loose connection will lead fire or creepage.
● Grounding terminal should be reliable grounding braking unit, or get an electric
shock risk.
●Do not touch the brake unit, the internal spares and printing board after the brake unit
is connected, otherwise it will lead to electric shock. There is high voltage direct
current inside.
●Don't let the cable damage from weight hanging and over load, or get an electric
shock risk.
●The unit and brake resistor should be installed on the medium with flame retardancy
(such as metal), away from combustible material, otherwise may cause fire
●Please check the wiring is correct before operation. Please confirm whether the input
DC voltage and brake unit voltage same level; Whether Input terminal (+, -) and
resistance terminal (RB1, RB2) connection position is correct; And check the
peripheral circuit of the connected to the drive for short circuit phenomenon, whether
the line is fastening, otherwise cause damage of drive.
●Please check whether master-slave choice and voltage grade Settings are correct.
●During the running, do not touch any spares inside.
●The repairs and maintenance task can be performed only when the inverter bus
voltage is lower than DC 36V, Power off more than ten minutes.Otherwise, the
residual charge from capacitor would cause personal injury!
Attention
● Do not use any brake unit and brake resistor lack of or with damaged spares.
●Do not touch the internal spares for there are CMOS spares on the control card of the
brake unit. Otherwise it will damage the spares.
●When many pieces brake units installed in parallel when used in the same case, please
install the fan or other cooling device.
●Ensure the right setting of brake unit and brake resistor.
●Do not make voltage resistance test on the brake unit, or it will lead semiconductor

Description: In the operation of three-level menu, you can press PRG or ENTER to return to
the second-level menu. The difference between the two is: Press ENTER key to save the set
parameters and return to the secondary menu, and automatically transfer to the next function code;
Pressing the PRG key directly returns to the secondary menu, without storing parameters, and
returns to the current function code.

In the third menu state, if the parameter has no flicker bits, it means that the function code can
not be modified. The possible reasons are as follows:
1) The function code is an unmodifiable parameter. For example, the actual detection
parameters, operation record parameters and so on.
2) The function code can not be modified in the running state, and can not be modified until
the downtime.

☆
This parameter is used to set the starting braking voltage of the braking unit.
220V voltage level, default braking voltage is 350V;

F0.01
Braking hysteresis voltage

☆
This parameter is used to set the hysteresis voltage during braking.
Generally when setting braking start voltage and braking stop voltage, there must be a
hysteresis loop. Such as settings F0.00=670V,F0.01=20V,when the bus voltage d0.00 is higher
than F0.00, start braking. When the bus voltage d0.00 is lower than (F0.00-F0.01), stop braking.
When the original state is in braking state, and the value of d0.00 is within F0.00 ~ (F0.00-
F0.01), the braking state is maintained.
F0.02
Default brake voltage selection

★
This parameter is used to set the default braking voltage for different voltage levels.
When setting to 0, corresponding to 220V voltage level, the default braking voltage is 350V;
When setting to 1, corresponding to 380V voltage level, the default braking voltage is 670V;
When setting to 2, corresponding to 480V voltage level, the default braking voltage is 760V;
F0.03

☆
This parameter is used to select the braking rate.
When braking rate is set to 100%, it shows that the braking is fully open, at this time the
braking effect is the best, with the fastest voltage drop, but the brake resistor temperature rises
quickly.
When the braking rate is set to 0%, it shows that the braking is turned off, at this time even
if it reaches the braking condition, the braking does not work.

Chapter 5 Brake unit and brake resistor
5-1 Brake unit
5-1-1.Brake voltage selection is based on below two conditions:
(1) According to the input voltage level of inverter , choose the brake unit with relative
voltage level
(2) According to the required braking power when inverter is braking , choose the brake
unit with relative power .
The principle of brake unit power selection is that the power of brake unit is greater than the
braking power . in the case where the braking power is not specified , please estimate according to
below ways :
Pb=P*Td*K
In this formula:Pb-----braking power;
P----- motor power
K----- mechanical energy conversion efficiency,the general value is 0.7
Td---- ratio of brake torque to motor rated torque
Td values vary in different systems , as shown in the following table.
Common
applications

crane
Uncoiler and

5-1-2.Brake resistor resistance selection
When it is braking, the regenerative energy of the motor is almost consumed on the brake
resistor ,according to the formula:
U*U/R=Pb
In the formula:U----- braking voltage in stable braking system
(vary in different systems , for 220VAC system usually choose 380v; for 380VAC system
usually choose 700V, for 480VAC system usually choose 800V)
Note: when the value of R is less than the minimum resistance of each voltage level, multiple
brake units are required.
5-1-3.Brake unit power selection
In theory , the power of brake resistance is same as the braking power , but considering
derating is 70%. according to formula:
0.7*Pr=Pb*ED
In the formula:Pr-----brake unit power
ED----- braking frequency , the proportion of braking process in the whole working process
