Cause:
Internal parameter data is corrupted.
Fault value (r0949, hexadecimal):
01: EEPROM access error.
02: Too many blocks in the EEPROM.
Remedy:
Replace the module.
F31806
Encoder 1: Initialization unsuccessful
Reaction:
ENCODER (DCBRAKE, NONE)
Acknowledge:
READY
Cause:
The encoder was not successfully initialized.
Fault value (r0949, hexadecimal):
1, 2, 3: Encode initialization with the motor rotating.
Remedy:
Acknowledge the fault.
Acknowledgment:
This fault can only be acknowledged by canceling the pulses.
F31811
Encoder 1: Encoder serial number changed
Reaction:
ENCODER (NONE, OFF2)
Acknowledge:
IMMEDIATELY
Cause:
The serial number of the motor encoder of a synchronous motor has changed. This means that it may be necessary
to re-calibrate/re-adjust the commutation angle.
- an encoder was replaced.
- re-commission a build-in motor or third-party motor.
- the firmware was updated to a version that checks the encoder serial number.
Remedy:
Calibrating/adjusting the commutation data in p0431. The calibration/re-adjustment can be automatically initiated
using a rotor position identification routine with p1990 = 1.
If calibration/adjustment is not required, then the serial number can be directly transferred using p0440 = 1.
F31820
Encoder 1 DRIVE-CLiQ: Telegram error
Reaction:
ENCODER (DCBRAKE, NONE)
Acknowledge:
IMMEDIATELY
Cause:
DRIVE-CLiQ communications error between the control unit and the encoder involved.
Fault value (r0949, hexadecimal):
01: CRC error.
02: Telegram is shorter than specified in the length byte or in the receive list.
03: Telegram is longer than specified in the length byte or in the receive list.
04: The length of the receive telegram does not match the receive list.
05: The type of the receive telegram does not match the receive list.
06: The address of the encoder in the telegram and in the receive list do not match.
07: The encoder expects a SYNC telegram, but the receive telegram is not a SYNC telegram.
08: The encoder does not expect a SYNC telegram, but the receive telegram is a SYNC telegram.
09: The error bit in the receive telegram is set.
10: The receive telegram is too early.
Remedy:
- carry-out a POWER ON.
- check the electrical cabinet design and cable routing for EMC compliance
- check the DRIVE-CLiQ wiring (interrupted cable, contacts, ...).

F31835
Encoder 1 DRIVE-CLiQ: Cyclic data transfer error
Reaction:
ENCODER (DCBRAKE, NONE)
Acknowledge:
IMMEDIATELY
Cause:
DRIVE-CLiQ communications error between the control unit and the encoder involved. The nodes do not send and
receive in synchronism.
Fault value (r0949, hexadecimal):
21: The cyclic telegram has not been received.
22: Timeout in the telegram receive list.
40: Timeout in the telegram send list.
