6 - 6 DCS 600 Manual for 12 – Pulse Operation
Slave
• 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.
12 – pulse pa
r-
allel mode
• 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
Note: The continuous current flow limits are different for
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).
Note: The maximum unbalanced current [parameter (47.04)]
of the T-reactor delivered by ABB Lampertheim will be
10 % of rated current!
