A07550 (F, N) Drive: Not possible to reset encoder parameters
Message class: Hardware/software error (1)
Reaction: NONE
Acknowledge: NONE
Cause: When carrying out a factory setting (e.g. using p0970 = 1), it was not possible to reset the encoder parameters. The
encoder parameters are directly read out of the encoder via DRIVE-CLiQ.
Alarm value (r2124, interpret decimal):
Component number of the encoder involved.
Remedy: - repeat the operation.
- check the DRIVE-CLiQ connection.
F07551 Drive encoder: No commutation angle information
Message class: Error in the parameterization / configuration / commissioning procedure (18)
Reaction: OFF2 (IASC/DCBRK)
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: For 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) for motor encoders without absolute position information.
Then, using an encoder adjustment (p1990), the angular commutation offset should be determined.
For 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.

revolutions), p0433 (Gearbox factor motor/load revolutions)
F07552 (A) Drive encoder: Encoder configuration not supported
Message class: Error in the parameterization / configuration / commissioning procedure (18)
Reaction: OFF2 (IASC/DCBRK, NONE, OFF1, OFF3, 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):
ccccbbaa hex: cccc = fault cause, bb = component number, aa = encoder data set
cccc = 1: encoder sin/cos with absolute track (is supported by SME25).
cccc = 3: Squarewave encoder (this is supported by SMC30).
cccc = 4: sin/cos encoder (this is supported by SMC20, SMI20, SME20, SME25).
cccc = 10: DRIVE-CLiQ encoder (is supported by DQI).
cccc = 12: sin/cos encoder with reference mark (this is supported by SME20).
cccc = 15: Commutation with zero mark for separately excited synchronous motors with VECTORMV.
cccc = 23: Resolver (this is supported by SMC10, SMI10).
cccc = 65535: Other function (compare r0456 and p0404).
