Alarm messages appear on the seven-segment display of the
SDCS-CON-x computer board as Code A ... and on the LC display
of the CDP 31x display and control unit as plaintext. They are
displayed only if no error message is active. Alarm messages (with
the exceptions of A 101 and A 102) do not cause the signal 10910
to be cancelled or the drive to be switched off.
The error and alarm messages are listed in several languages in
Chapter 10.
The status of the drive functions (autotuning controllers, saving va-
lues) is indicated by the status signals 11201 and 11202. The sta-
tus of the first and/or second field supply unit, the torque control
and the current controller is indicated by the signals 11203 to
11205, and is regularly updated by the power converter software,
enabling users to check it when one of the three signals is selec-
ted.
Depending on the unit being used (CDP 31x or CMT Tool), plain-
text or a number will be shown on the display/screen. This number
constitutes a code, which is equivalent to the plaintext for signal
11201; for all others, it is a binary-coded decimal number (the 16-
bit word with the binary value for each signal is converted into de-
cimal).
Parameter Code/Bit
11201 0...49 COMMIS_STAT: result of a drive function. Provides as feedback the sta-
tus information when the parameter DRIVEMODE (1201) was used to
start a drive function.
50...61 Provides as feedback the status information when the parameter
DRIVEMODE (1201) was used to start the drive functions 3, 5 or 6 (auto-
tuning).
11202 0...6 BACKUPSTOREMODE: status of this operating mode. This operating
mode is used to pass commands to the drive's parameter handling routi-
ne.
7...17 During command execution, the value of BACKUPSTOREMODE shows
what is happening, or the cause of the error if the command fails.
11203 -- FEXC_STATUS: status of field exciters 1 and 2
11204 -- TC_STATUS: status of the torque control
11205 -- BC: current controller status. If the value of BC = 0, everything is in order.
Otherwise, the different bits of BC will indicate the cause of the current
controller disable.
