Overview of Alarms
Remedy: Re causes 1, 4:
Accept the new serial number with p0440 = 1.
Re causes 2, 3:
Carry-out an automatic adjustment using the pole position identification routine. First,
accept the serial number with p0440 = 1. Acknowledge the fault. Initiate the pole position
identification routine with p1990 = 1. Then check that the pole position identification routine
is correctly executed.
or
Set the adjustment using parameter p0431. In this case, the new serial number is
automatically accepted.
or
Mechanically adjust the encoder. Accept the new serial number with p0440 = 1.
231820 <location>Encoder 1 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, ...).

231835 <location>Encoder 1 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.
