232805 <location>Encoder 2: Incorrect EPROM checksum
Reaction: A_INFEED: OFF2 (NONE)
SERVO: ENCODER (DCBRAKE, NONE)
Acknowledge: IMMEDIATELY
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.
232806 <location>Encoder 2: Initialization unsuccessful
Reaction: A_INFEED: OFF2 (NONE)
SERVO: 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.
232820 <location>Encoder 2 DRIVE-CLiQ: Telegram error
Reaction: A_INFEED: OFF2
SERVO: 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, ...).

232835 <location>Encoder 2 DRIVE-CLiQ: Cyclic data transfer error
Reaction: A_INFEED: OFF2
SERVO: 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.
Remedy: - carry-out a POWER ON.
- replace the component involved.
