3.2.1.7 Dynamic Brake Connections

For NEMA 1 and NEMA 4X Drives rated up to 30HP (22kW) the Dynamic Brake connections are made as illustrated

herein. Refer to the SMV Dynamic Brake Instructions (DBV01) for complete information.

NEMA 1 (IP31) up to 30HP (22kW) NEMA 4X (IP65) up to 30HP (22kW)

The SMV 40...60Hp (30...45kW) models include a dynamic brake transistor as standard and only require the connection

of an external resistor kit for dynamic braking operation. The dynamic brake resistor connections for 40...60 Hp

(30...45kW) drives are standard built-in connections as illustrated in the diagram below. In the 40Hp (30kW) model

drives, the dynamic brake connector is on the right-hand side of the drive and the terminals from top to bottom are B-,

BRAKE and B+. In the 50/60HP (37.5/45 kW) model drives, the dynamic brake connector is on the left-hand side of the

drive and the terminals from top to bottom are B+, BRAKE and B-.

External resistor kits must be connected to terminals B+ and BRAKE (no connection to B-). Refer to the table herein

for external resistor kit selection. Refer to parameter P189 for enabling the dynamic brake function in the 40...60Hp

(30...45kW) models.
