DCS 500 manual Status Signals, 11201

Chapter 4 - Signals and Troubleshooting

4.6 Status Signals

The status of drive functions (autotuning of controllers; saving val- ues) is shown by status signals named 11201 and 11202. The status of the first and / or the second field exciter, the torque control sequencing and the current controller is shown by the signals 11203 to 11205.

In case of a drive function, which is started by setting a parameter to a defined value the status is indicated automatically on the LCD display of the panel CDP 31x in plain text. The indication will show the result directly or will cross-reference to the final location.

The status of the field exciter(s), torque control and current control- ler is updated regularly by the converter software and can be checked if one of the three signals is selected.

Depending on the tool in use (CDP 31x or CMT tool) the plain text or a number appears on the display / screen. This number repre- sents a code which is equivalent to the plain text for signal 11201; for all others it´s a binary coded decimal number (the 16 bit word with the binary value for each signals is transferred to decimal).
