Drive control connections
The control connections are made on the terminal blocks provided in the swing-out
frame of the drive. Refer to the circuit diagrams delivered with the drive, and to the
chapter
Supply unit control connections
The supply unit is controlled using the local control devices mounted on the cabinet
door, or the buttons on the DSSB board. No external control connections by the user
are needed. However, the user can connect certain external devices to the supply
module. It is possible to:
• control the supply unit through the remote control inputs (On, Start, Reset,
External fault)
• halt the supply unit by an external emergency stop button (if the unit is equipped
with a local emergency stop button)
• read supply unit's status information through the relay outputs (Fault, Running,
External 48 VDC supply on, Earth fault, emergency stop)
• feed the supply unit's control boards from an external +48 VDC supply.
Refer to the circuit diagrams delivered with the drive for the connection terminals for
the external control devices. For additional information on the control connections
see the ACA631/633 Cabinet-installed Diode Supply Unit (DSU) User's Manual
(Code: 64735501 [English]), available through ABB representatives.
