Diagram of the connection of paralleled running brake unit and inverter (Only PB6034 with this
function). If 2 or more over brake units are paralleled, please refer to the above diagram and connect
the inverters, multiple brake units and brake resistors.
6.1.
Host and slage select of function setting
(1) The factory setting of the brake unit is set to be the host (M), do not modify the factory setting
if only one brake unit is used.
(2) When 2 or more over brake units are paralleled, the control terminal (S) is used. Please refer
to the “Host and slave control
connection”.
6.2.
Host and slave control connection
(1) The brake unit has host/slave switch. Set the brake unit 1 to be
“M”, the brake unit 2
and 3
to be
“S”
(2) Connect separately M1, M2 of the brake unit 1 with S1, S2 of the brake unit 2; Connect
separately M1, M2 of the brake unit 2 with S1, S2 of the brake unit 3. Etc.
Note
:
Double wind the M1, M2 and S1, S2
,
and please make it as short as you can; the maximum
paralleled brake units is only 10.

7.1.
Why brake voltage 670V ?
Brake unit voltage is from 630V to 700V, how to select the right voltage? In China, it should select
according to Chinese electric net. Brake voltage should be on the following 2 standards:
•
Brake voltage should be large enough and not lead the brake unit misact because of
the raised voltage of the electric net.
The electric net fluctuates in China. Some places the voltage will be over AC 450V, the inverter DC
voltage is 640V, the safe voltage should be larger than that. If the brake voltage is set low, the brake
resistors may be burned. The actual fluctuation is ±20%.
•
Brake unit voltage should be low enough, make the inverter run at about the rated
voltage, ensure the safe running of the equipments.
