i950 Profibus module: In compatibility mode, the cyclically transmitted actual values (PLC input data) are incorrect (fixed as of V01.14.01)

     

Fixed as of: 

Servo inverter i950 FW: from V01.14.01

 

Behavior of the new version: 

The actual values of the inverter, which are sent cyclically via PROFIBUS as input data to the PLC, are now always up to date and correspond to the actual values calculated by the application.

 

Description of behavior: 

The actual values sentcyclically via PROFIBUS of the drive are not transmitted correctly. Instead of the current actual values, the value "0" is permanently is permanently sent to the PROFIBUS PLC.

Conditions under which the behavior occurs: 

  • i950 with PROFIBUS module and
  • parameter 0x2341:11 "Compatibility mode" is set to a value > 0 (migration mode)

Affected products: 

Servo inverter i950 FW:  Only V01.14.00 affected

Short-term measures, recommendations, assessment: 

Update the device firmware to the new version with the correction of the described functional restriction.
