Siemens SINAMICS S210 - Drive: Command Data Set CDS Not Present; Drive: Data Set Changeover Not Possible; A07550 (F, N) Drive: Not Possible to Reset Encoder Parameters; Drive Encoder: no Commutation Angle Information

A07531 Drive: Command Data Set CDS not present
Message value: -
Drive object: All objects
Reaction: NONE
Acknowledge: NONE
Cause: The selected command data set is not available (p0836 > p0170). The command data set was not changed over.
Remedy: - select the existing command data set.
- set up additional command data sets.
A07541 Drive: Data set changeover not possible
Message value: -
Drive object: All objects
Reaction: NONE
Acknowledge: NONE
Cause: The selected drive data set changeover and the assigned motor changeover are not possible and are not carried out.
For synchronous motors, the motor contactor may only be switched for actual speeds less than the speed at the start of
field weakening (r0063 < p0348).
See also: r0063
Remedy: Reduce the speed to below the speed at the start of field weakening (r0063 < p0348).
A07550 (F, N) Drive: Not possible to reset encoder parameters
Message value: %1
Drive object: All objects
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.
Reaction upon F: Servo: NONE (IASC/DCBRK, OFF1, OFF2, OFF3, STOP2)
Acknowl. upon F: IMMEDIATELY (POWER ON)
Reaction upon N: NONE
Acknowl. upon N: NONE
F07551 Drive encoder: No commutation angle information
Message value: Fault cause: %1, drive data set: %2
Drive object: All objects
Reaction: Servo: 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.
