Chapter 4 – Commissioning the Supply Section with ISU

ACA 635 IBGT Supply Sections
Controlling the ISU
with an Overriding
System
This procedure instructs how to control or monitor the IGBT supply unit
from an overriding system by using data sets 1 and 2 or 10 to 33 with
DDCS and DriveBus communication protocols.
Action
Parameter
Set this parameter to MCW if the ISU will be controlled with
an overriding system. Set to I/O if the ISU is only monitored.
98.01 COMMAND SEL
Set this parameter to FBA DSET1 or FBDSET 10 depending
on what datasets the overriding system uses.
98.02 COMM MODULE
Connect the fibre optic cables to channel CH0 on the NAMC
board.
Set the node address and communication mode for channel
CH0 as follows:
70.01 CH0 NODE ADDR
71.01 CH0 DRIVEBUS MODE
Note:
Setting of Par. 71.01 is valid after
the next power-up.
Check that the communication is working.
Set the delay time for a coommunication fault indication.
70.04 CH0 TIMEOUT
Select the action upon a communication fault on channel
CH0.
70.05 CH0 COMM LOSS CTRL
Select RING, if channels CH0 on the NAMC boards are
connected in a ring. The dafault setting STAR is typically
used with DDCS branching units NDBU-85/95.
