Diagram 1-2 Connection between inverter and braking unit
NOTE:
(1)
Braking resistor power derating coefficient had better not more than 30%, otherwise there
is the risk of fire.
(2)
The device of 22kw and below 22kw are matched with built-in breaking unit , the device
of 30KW and above need to be connected with braking unit outside.
(3)
Wiring of braking resistor should be less than 5m;The braking resistor would have
temperature rise due to feedback energy consumption during dynamic braking, please ensure
the safety protection and good ventilation.
Braking resistance value and power are selected according to the actual situation, the
greater of the system inertia, the shorter of the deceleration time, the more frequent braking,
