F50, F51
Electronic Thermal (Discharging capability and Allowable average loss)
These function codes configure the electronic thermal overload relay to protect the
braking resistor from overheating.
Set the discharging capability and allowable average loss to F50 and F51, respec-
tively. Those values differ depending upon the specifications of the braking resistor.
Refer to the tables on the next page.
Depending on the discharging capability margin of a braking resistor, the
electronic thermal function may operate and issue the overheat alarm

," even if the actual temperature of the resistor is lower than that
specified. Check braking resistor performance again and review the data
setting of function codes F50 and F51.
