• SGDM-3GADB SERVOPACK
SGDH-3GAEB, SERVOPACK
SGDH-3GDEB, -4EDEB , -5EDEB , -9ZDEB SERVOPACKs
The dynamic brake contactor and surge absorption unit are not built into the SERVOPACK.
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.
