Emergency

Was bedeutet F13.12 ?

Encoder 1 has transmitted an emergency error message, indicating a critical internal or communication issue requiring immediate attention. This is often triggered by severe interference or incorrect communication parameters, leading to loss of position control.

• Severe internal fault within the encoder unit, often indicated by an internal diagnostic LED on the encoder.
• Catastrophic communication bus failure (e.g., CANopen 'bus off' state) preventing normal data exchange.
• Excessive electromagnetic interference (EMI) causing unrecoverable data errors on the communication link.
• Incorrect network termination or excessive bus length causing signal reflection and communication instability.
• Encoder's internal software or firmware corruption leading to an unhandled exception.

1. 1

   Check the diagnostic LED(s) on the encoder unit itself for specific error codes or states (refer to encoder manual).

2. 2

   Verify the communication cable integrity, especially for shorts to ground or supply voltage on data lines.

3. 3

   Measure the bus termination resistors at both ends of the communication network to ensure correct values (e.g., 120 Ohms for CANopen).

4. 4

   Power cycle the encoder and the drive, then attempt to re-initialize the communication network (Parameter P7-00 set to 1).

5. 5

   Isolate the encoder from the network and re-connect it directly to the drive (if possible) to see if the emergency message persists.
