9 CDBR Braking Unit and LKEB Braking Resistor Selection
◆ CDBR Braking Unit and LKEB Braking Resistor Selection
Select a CDBR Braking Unit and LKEB Braking Resistor Unit based on application-specific
requirements and the selected AC drive.
Refer to the local catalog for selections based on other drive models.
◆ CDBR Braking Unit Fault Circuit Connection Diagrams

<1> 200 V class drives do not require a control circuit transformer.
<2> Set L3-04 to 0 or 3 to disable Stall Prevention during deceleration when using an LKEB Braking Resistor Unit.
Enabling the function under these conditions may prevent the drive from stopping within the specified
deceleration time.
