Installing a Braking Unit Connection: CDBR Type

To install a CDBR type braking unit, connect the terminal +3 of the drive to the terminal + on the braking unit.

Next, wire together the terminal - on the drive and braking unit. The terminal +2 is not used.

Set L8-55 = 0 [InternalBrakingTransistorProtect = Disable].

To install a CDBR type braking unit to the drive with a built-in braking transistor (models 2004 to 2138, 4002 to 4168), connect the

drive terminal B1 to the terminal + on the braking unit. Next, wire the terminal - on the drive and braking unit together. Terminal B2 is
