Connecting the Braking Resistor Unit and Braking Unit
•
Connect the Braking Resistor Unit and Braking Unit to the Inverter as shown in the following diagrams.
•
For the 3G3FV, set L8-01 to “0” (i.e., no overheating protection of the braking resistor) and L3-04 to “0”
(i.e., no decelerating stall prevention) or “2” (braking function with stall prevention) before using the
Inverter with the Braking Resistor Unit connected.
•
For the 3G3HV, set n079 to “1” and n070 to “0.”
Note 1. Set L8-01 to “1” (n079 to “1”) when operating the Inverter with the braking resistor without
thermal relay trip contacts.
Note 2. The Braking Resistor Unit cannot be used and the deceleration time cannot be shortened by
the Inverter if L3-04 (n070) is set to “1” (i.e., decelerating stall prevention).
•
To prevent the Unit from overheating, make a power supply sequence as shown below or connect the
thermal relay trip output of the Unit to the external fault input terminal of the Inverter to interrupt the
running of the Inverter.
