B.1 Braking Resistor
When the inverter with high inertia loads or need to slow down rapid deceleration
,
Motor will in the
state of power generation, the energy is transferred to the inverter DC link via the inverter bridge,
causing the bus voltage of the inverter rises, when more than a certain value, the inverter will report
overvoltage fault, and even lead to inverter power module damage of overvoltage, to prevent this
happening, you must configure the brake components.
FR200 versatile compact inverter series are all built-in brake unit, customers simply external
braking resistor can be used.
The following is recommended braking resistor power rating and
resistance. Depending on the load, the user can change the values appropriately, but must be within
the recommended range.

Remark
:
Multiple braking resistors are connected in parallel mode.
For example FR200-4T-022G/030PB
inverter braking resistor selection: Recommend selecting two 2KW, 30Ω resistor in parallel connection,
Equivalent braking resistor is 4KW, 15Ω.
If the power rating over 90kw, please refer to
《
FRBU User's Manual Of Braking Unit
》
to select the
braking resistor.
Cables listed in above table refer to the lead cable of single resistor. The DC bus should
be
updated if the resistors are in parallel connection.
Cable should withstand voltage above AC450V,and
temperature resistance of cable: 105
℃
