The fault signals will be shown on the seven segment display of the 
control board SDCS-CON-x as codes F . . as well as on the LCD of 
the control panel CDP 31x as clear text. 

All fault signals - with the exception of 

, 

 and 

 - can be 

reset (after elimination of the faults); 

would be

self resetting, if 

the communication had been re-established before. 

For resetting (RESET) of fault signals the following steps are re-
quired: 

• 

Switching off the commands ON/OFF and RUN 

• 

Elimination of the faults 

• 

Fault acknowledgement, i.e. resetting (RESET) 
  

a)  as described for CDP 31x 

 

 

b) by short-time setting of the command RESET  

  

  to high (logical one) via a binary input  

  

  (default setting = DI6). 

• 

Depending on the application conditions generate the commands 
ON/OFF and RUN once more. 

The fault signals will result in switching off the signal

 resp. in 

stopping the drive (installation-dependent). 

(1) Fault will switch off the signals

 

(2) Fault will switch off the signals

 

(3) Fault will switch off at least the signal

 

 

 

Auxil. undervoltage 

Try to reset. Check internal auxiliary volt-
ages;

if fault persists, change SDCS-CON-x 

and/ or SDCS-POW 1 board (if required).

Overcurrent 

 

Check:  - Motor, load and armature cabling 
 

 

  for faults or blocking condition; 

 

 

- Parameter setting of current con- 

 

 

  trol circuit/torque limitation; 

   - 

Parameter

  

    

(overcurrent 

detection).
