2.17 Braking Resistor Installation

YASKAWA SIEPC71061723A YASKAWA AC Drive CR700 Technical Manual 117

Note:

A junction terminal is required when connecting a braking resistor unit (LKEB type) to 2145, 2180, 4112, and 4150.

Install and wire a junction terminal that can be connected to power lines that allow for connection with the drive peripheral device and

options according to specifications.

The following table lists recommended junction terminals. Contact Yaskawa or your nearest sales representative for details on selection

and installation of the junction terminal.

Figure 2.126 Installing a Braking Resistor Unit: LKEB type (Example: 2003 to 2115, 4002 to 4150)

◆ 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 [Internal DB TransistorProtection = Disable].

Note:

• To install a CDBR type braking unit to the drive with a built-in braking transistor (models 2003 to 2115, 4002 to 4150), 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

not used.

• A junction terminal is required when connecting a braking unit (CDBR series) to the drive models 2145, 2180, 4112, and 4150.
