Note: Contact your Yaskawa representative or the nearest Yaskawa sales office when using a CDBR-XD
model Braking Unit with CDBR-X or CDBR-XB models.
<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.
<3> Connect directly to the drive terminal or install a terminal block.
<4> Set one of the CDBR Braking Units as the master and set all others as slaves when using more than one CDBR
Braking Unit connected in parallel.
