Electronic Thermal Overload Protection for Braking Resistor

(Discharging capability and Allowable average loss)
A braking resistor can be mounted on inverters of 0.4 kW or above.
These function codes specify the electronic thermal overload protection feature for the
braking resistor.
Set F50 and F51 data to the discharging capability and allowable average loss, respectively.
Since those values differ depending on the specifications of the braking resistor, refer to the
tables given below.
Depending on the thermal marginal characteristics of the braking resistor, the
electronic thermal overload protection feature may act so that the inverter issues
the overheat protection alarm dbH even if the actual temperature rise is not
enough. If it happens, review the relationship between the performance index of the
braking resistor and settings of related function codes.
The tables below list the discharging capability and allowable average loss of the braking
resistor. These values depend upon the inverter and braking resistor models.
