Note: Contact your Yaskawa representative or the nearest Yaskawa sales office when using the CDBR
Braking Unit (CDBR-D) with earlier models (CDBR- or CDBR-B)
<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.
The motor may not stop within the deceleration time if this setting is not changed.
<3> Connect directly to the drive terminal or install a terminal block.
<4> When using more than one CDBR Braking Unit connected in parallel, set one of the CDBR Braking Units as the
master, and set the others as slaves.
