• Writing of value 1 to parameter 74-ERES via control unit or bus

• By way of the error reset bit in the control word
• Transition from SYSTEM START to SYSTEM STOP
After an error reset the state machine of the device (EasyDrive or
DRIVECOM) assumes the same state as after power-on. That is to say,
the control must be restarted.
For initial system diagnosis, the module has two
LEDs (H4 and H5).
LED H5 indicates a correct voltage supply.
