Error
Encoder fault
Encoder fault
1) Error message only important for 9300 position controllers
2) Error message only important for 9300 cam profilers
3) Temperature detection via resolver or incremental encoder
Cause
1. Absolute encoder with RS485 interface does not
transmit data.
2. Defective encoder electronics
•
TIP: The encoder must not rotate during mains
connection.
1. The plug of the SinCos encoder or controller
(terminal X8) is not plugged in properly.
2. A fault occurred in the connection cable of the
SinCos-encoder
3. Defective encoder electronics
Fault messages
Remedy
1. Check supply cable. Check encoder.
2. Replace defective encoder
3. Check voltage supply C0421.
4. No Stegmann encoder connected.
•
TIP: If the error message occurs after you have
selected the absolute value encoder, disconnect
and reconnect the mains voltage to remove the
error message. The error message is caused by
an encoder not initialised yet.
1. Check cable for open circuit or short circuit.
2. Replace defective encoder
•
TIP: Set the error reaction TRIP
(code C0580 = 0) especially for monitoring
encoder of a synchronous machine.
