Chapter 5 - Preparing the Converter
5.1 Selection Switches and Protective Settings
Settings of control board selection switches, protective circuit breakers
of fans and pumps, earth fault relays and timers etc. must be checked
according to the project related circuit diagrams. See
ACS 6000 User’s Manual, Appendix D – Electrical Drawings.
1 Check that the node addresses of the I/O cluster modules in COU,
WCU and possible customer specific control cabinets are as
specified in the circuit diagrams.
2 In case of a synchronous drive:
1 Check the node address switches or jumpers of
excitation control boards (CCB, PAI, MTR and
MUB boards) in EXU cabinet according to the
wiring diagrams.
2 Check the node address switch of the rotor shaft
position measurement unit (GRB unit) in the
COU cabinet.
When finished, check off the above mentioned items in the
commissioning report.
The supportline must be informed if any changes have been made!
5.2 Connecting the Auxiliary Supply
Normally, the ACS 6000 is connected to a 3-phase 380….690 VAC
auxiliary supply. Typically, there may also be a single-phase secured
auxiliary supply for the control electronics.
The terminals and the main switch of the auxiliary supply are located in
the WCU cabinet. Before closing the main switch, proceed as follows:
1 Make sure that all auxiliary switches, optional circuit breakers and
protection switches have been switched off and power supplies
have been removed from the boards.
Note: Do not switch on the motor protection switches of the cooling
pumps before the cooling system has been filled. If a pump runs dry
the pump seals will be damaged immediately.
Since the software has already been downloaded to the AMC board
in the factory, the pumps will start after the Emergency OFF signal
has been reset, depending on the setting of parameter 33.20.
