• SGDH-3GDE, 4EDE, 5EDE SERVOPACKs
The dynamic brake contactor and Surge Absorption Unit are built into the Dynamic
Brake Unit. Connect the DU, DV, and DW terminals and the Frame Ground ( ) on the
Dynamic Brake Unit, and also connect the terminals DBON and DB24 for dynamic
brake contactor control, as shown in the following diagram.
Using Dynamic Brake Resistors Prepared by the Customer
• SGDH-2BDE, 3ZDE SERVOPACKs
The dynamic brake contactor and Surge Absorption Unit are built into the SERVO-
PACK. Connect the dynamic brake resistors only, as shown in the following diagram.
Note: Connect dynamic brake resistors with the following resistance speci-
fications.
