High-function General-purpose Inverter 3G3RX-V1 User’s Manual (I578-E1)
7-1 Monitor Mode (Group d)
7
Use this function to display the inverter DC voltage called “P-N voltage” (the DC voltage between the
P/+2 and N/– terminals of the inverter.)
During operation, the monitor value changes according to the actual DC voltage of the inverter.
Use this function to display the regenerative braking load rate. If this monitor value exceeds the value
set in the Usage Rate of Regenerative Braking (b090), the inverter will cause a trip with the alarm code
E06 (Braking resistor overload protection).
Use this function to display the electronic thermal load rate. If this monitor value exceeds 100%, the
inverter will cause a trip with the alarm code E05 (Overload protection).
