 External braking resistor
Standard Models
The braking resistor is protected from overheating by a thermal relay incorporated in the braking
resistor. Assign "Enable external alarm trip" THR to one of the inverter’s digital input terminals [X1],
[X2], [X3], [FWD], and [REV], and connect it to the terminals 2 and 1 of the braking resistor.
If you choose not to use the thermal relay incorporated in the braking resistor, set up the overheat
protection device using the values given in the table below.
