Encoder 1: Requested Cycle Or Rx-/Tx Timing Not Supported; Encoder 1: Hardware Logic Unit Failed - Siemens SINAMICS DCM List Manual

4 Faults and alarms
4.2 List of faults and alarms
Note:
With closed-loop position control, the serial number is accepted when starting the adjustment (p2507 = 2).
When the encoder is adjusted (p2507 = 3), the serial number is checked for changes and if required, the adjustment
is reset (p2507 = 1).
Proceed as follows to hide serial number monitoring:
- set the following serial numbers for the corresponding Encoder Data Set: p0441= FF, p0442 = 0, p0443 = 0, p0444
= 0, p0445 = 0.
- parameterize F07414 as message type N (p2118, p2119).

Remedy: Re causes 1, 2:
Carry out an automatic adjustment using the pole position identification routine. Acknowledge fault. Initiate the pole
position identification routine with p1990 = 1. Then check that the pole position identification routine is correctly
executed.
SERVO:
If a pole position identification technique is selected in p1980, and if p0301 does not contain a motor type with an
encoder adjusted in the factory, then p1990 is automatically activated.
or
Set the adjustment via p0431. In this case, the new serial number is automatically accepted.
or
Mechanically adjust the encoder. Accept the new serial number with p0440 = 1.
Re causes 3, 4:
Accept the new serial number with p0440 = 1.
Reaction upon F: NONE (ENCODER, OFF2)

F31812 (N, A)

Encoder 1: Requested cycle or RX-/TX timing not supported

Message value: %1
Message class: Error in the parameterization / configuration / commissioning procedure (18)
Drive object: DC_CTRL, DC_CTRL_R, DC_CTRL_R_S, DC_CTRL_S
Reaction: OFF2
Acknowledge: IMMEDIATELY
Cause: A cycle requested from the Control Unit or RX/TX timing is not supported.
Fault value (r0949, interpret decimal):
0: Application cycle is not supported.
1: DRIVE-CLiQ cycle is not supported.
2: Distance between RX and TX instants in time too low.
3: TX instant in time too early.
Remedy: Carry out a POWER ON (power off/on) for all components.
Reaction upon N: NONE
Acknowl. upon N: NONE
Reaction upon A: NONE
Acknowl. upon A: NONE
F31813

Encoder 1: Hardware logic unit failed

Message value: Fault cause: %1 bin
Message class: Hardware / software error (1)
Drive object: DC_CTRL, DC_CTRL_R, DC_CTRL_R_S, DC_CTRL_S
Reaction: ENCODER (IASC/DCBRK, NONE)
Acknowledge: PULSE INHIBIT
Cause: The DRIVE-CLiQ encoder fault word supplies fault bits that have been set.
Fault value (r0949, interpret binary):
Bit 0: ALU watchdog has responded.
Bit 1: ALU has detected a sign-of-life error.
Remedy: Replace encoder.
