Drive Encoder: No Commutation Angle Information; Drive Encoder: Encoder Configuration Not Supported - Siemens Sinamics S120 Diagnostic Manual

207551 <location>Drive encoder: No commutation angle information
Message value: Fault cause: %1, drive data set: %2
Drive object: SERVO_COMBI, SERVO_SINUMERIK828
Reaction: OFF2 (IASC/DCBRAKE)
Acknowledge: IMMEDIATELY (POWER ON)
Cause: The commutation angle information is missing. This means that synchronous motors cannot be controlled (closed-loop
control)
Fault value (r0949, interpret decimal):
yyyyxxxx dec: yyyy = fault cause, xxxx = drive data set
yyyy = 1 dec:
The motor encoder used does not supply an absolute commutation angle.
yyyy = 2 dec:
The selected ratio of the measuring gear does not match the motor pole pair number.
Remedy: Re fault cause = 1:
- check the encoder parameterization (p0404).
- use an encoder with track C/D, EnDat interface of Hall sensors.
- use an encoder with sinusoidal A/B track for which the motor pole pair number (r0313) is an integer multiple of the
encoder pulse number (p0408).
- activate the pole position identification routine (p1982 = 1).
Re fault cause = 2:
- the quotient of the pole pair number divided by the ratio of the measuring gear must be an integer number: (p0314 *
p0433) / p0432.
Note:
For operation with track C/D, this quotient must be less than 8.

207552 <location>Drive encoder: Encoder configuration not supported
Message value: Fault cause: %1, component number: %2, encoder data set: %3
Drive object: SERVO_COMBI, SERVO_SINUMERIK828
Reaction: OFF2 (IASC/DCBRAKE, NONE, OFF1, OFF3, STOP1, STOP2)
Acknowledge: IMMEDIATELY (POWER ON)
Cause: The requested encoder configuration is not supported. Only bits may be requested in p0404 that are signaled as being
supported by the encoder evaluation in r0456.
Fault value (r0949, interpret decimal):
Low word low byte: Encoder data set number
Low word high byte: Component number
High word:
The encoder evaluation does not support a function selected in p0404.
1: sin/cos encoder with absolute track (this is supported by SME25).
3: Squarewave encoder (this is supported by SMC30).
4: sin/cos encoder (this is supported by SMC20, SMI20, SME20, SME25).
12: sin/cos encoder with reference mark (this is supported by SME20).
15: Commutation with zero mark for separately-excited synchronous motors with VECTORMV.
23: Resolver (this is supported by SMC10, SMI10).
65535: Other function (compare r0456 and p0404).
See also: p0404 (Encoder configuration effective), r0456 (Encoder configuration supported)
Remedy: - check the encoder parameterization (p0400, p0404).
- use the matching encoder evaluation (r0456).
