① Diagnostic LEDs for the drive controller:
• RDY/ERR = Drive status
• SAFE = Safety function status
② Diagnostic LEDs for the PROFINET communication:
• SF = PROFINET group error
• BF = PROFINET bus error
• MT = PROFINET maintenance request
• SYNC = PROFINET isochronous mode (IRT)
• ON = PROFINET communication started
③ Diagnostic LEDs for the sensor unit:
• 2DQx/2DIx = Status of digital inputs/outputs
• 5VSE = Output of supply voltage of motor encoder
• 2L+ = Infeed of supply voltage for the sensor unit
④ Diagnostic LEDs for power unit and logic unit:
• 4L+ = Infeed of supply voltage of power unit
• 1L+ = Infeed of supply voltage of logic unit
⑤ Diagnostic LEDs PROFINET ports and service (behind the lower front cover):
