If an external brake resistor is used, the settings of the parameters must be the same as the power
and resistance of the external brake resistor.
Note:
Brake overload detection should be used with P4.34. If P4.34 is set to 2, the brake overload
detection logic uses the external brake resistor parameters to execute fault detection. If this group
of parameter does not match the power and resistance of the external brake resistor, the brake
overload fault (Er07-0) may be reported by mistake or even the brake resistor may be burnt down.
The regenerative brake overload protection time of the external brake resistor is in direct
proportion to the two parameters and is in inverse proportion to the brake rate during actual
running. The two parameters are invalid when P4.34 is not 2.
