10.1.10 Monitor the Load Ratio of the Braking Resistor
 How to check the usage rate of the optional braking resistor?
BRD load ratio monitor [d103]
 Displays the usage rate of the braking resistor operation circuit (BRD).
 To use the braking resistor operation circuit (BRD), the "Dynamic brake use ratio [b090]" setting
is required. For details, refer to "9.9.5 Suppressing Overvoltage with Braking Resistor".
 If this monitor value exceeds the value set in "Dynamic brake use ratio [b090]", "Braking resistor
overload error [E06]" will occur.
 For troubleshooting when "Braking resistor overload error [E06]" occurs, refer to "15.2
Troubleshooting for Protection Functions Related Error" for details.
