The table below lists the discharging capability and allowable average loss of the braking resistor.
These values depend upon the inverter and braking resistor models.
 External Braking Resistors㩷
Standard models
The thermal sensor relay mounted on the braking resistor acts as a thermal protector of the motor for
overheat, so assign an "Enable external alarm trip" terminal command THR to any of digital input
terminals [X1] to [X5], [FWD] and [REV] and connect that terminal and its common terminal to
braking resistor's terminals 2 and 1.
To protect the motor from overheat without using the thermal sensor relay mounted on the braking
resistor, configure the electronic thermal overload protection facility by setting F50 and F51 data to
the discharging capability and allowable average loss values listed below, respectively.
