•
Commissioning the slave converter:
Isolate the master or suppress the firing pulses.
-
Commission the slave converter under current control as a
-
6 – pulse standard converter.
For how to proceed, please consult the relevant standard
documentation Operating Instructions DCS 600.
•
Commissioning the 12 – pulse operation:
- Set the parameters for 12 – pulse mode (15.16, 15.22,
47.09, ...)
(see "Chapter 3 – Twelve–Pulse Parallel
Configurations with DCS 600").
- Connect power sections of 12 – pulse master and slave to
the mains supply.
The result of the armature autotuning (6 – pulse mode) can
-
be used also for the 12 – pulse configuration:
ARM_L (41.11) 12 – pulse parallel = 2 x (41.11) 6 – pulse
ARM_R (41.12) 12 – pulse parallel = 2 x (41.12) 6 – pulse
The continuous current flow limits are different for
Note:
6 – pulse and 12 – pulse motor current!
- Check the settings of the two limits for continuous current
flow, and re-optimize the current controller parameters (the
current controller self-setting function cannot be used here).
•
Remaining procedures for full operation:
Optimize the speed controller parameters in the master.
-
Set/check the parameters for the monitoring features.
-
- Check the fault signals and the safety shutdown functions.
- Block Local Operation CDP 312 Panel for slave (16.04).
The maximum unbalanced current [parameter
Note:
of the T-reactor delivered by ABB Lampertheim will be
10 % of rated current!
