F07517 — Drive: Encoder data set changeover incorrectly parameterized

F07517 is raised when the drive detects that the encoder data set changeover is parameterized incorrectly: in at least two drive data sets (DDS), the same motor data set (MDS) is assigned different encoder data sets (EDS) for the motor encoder. An MDS is not permitted to have different motor encoders in various DDSs, so the drive rejects this configuration with a fault. The fault value in r0949 names the two drive data sets involved, and the drive coasts down until the conflict is corrected and the fault is acknowledged.

• In at least two drive data sets (DDS), one and the same motor data set (MDS) is assigned different encoder data sets (EDS) for the motor encoder — the drive does not permit an MDS to have different motor encoders in various DDSs.
• Example of the disallowed assignment: DDS0 uses MDS 0 with encoder data set 0 (p0186[0] = 0, p0187[0] = 0), while DDS1 uses the same MDS 0 with encoder data set 1 (p0186[1] = 0, p0187[1] = 1).

1. Read the fault value in r0949 and interpret it as a decimal number: the lower 16 bits indicate the first DDS, the upper 16 bits indicate the second DDS.
2. In the two drive data sets named by the fault value, compare p0186 (MDS number) and p0187 (encoder 1 EDS number): the conflict is present when both DDSs use the same MDS while p0187 assigns different encoder data sets for the motor encoder.
3. If the motor is to be operated once with one motor encoder and then with the other, set up two different MDSs in which the motor data are the same, so that each DDS has its own MDS. Example: DDS0: p0186[0] = 0, p0187[0] = 0; DDS1: p0186[1] = 1, p0187[1] = 1.
4. Then acknowledge the fault and restart the drive as described under reset.

• The drive stores the fault value in r0949; interpret the value as a decimal number.
• Lower 16 bits: the first DDS.
• Upper 16 bits: the second DDS.

• p0186 — MDS number: shows which motor data set each drive data set uses; in the corrected assignment each DDS is given its own MDS (p0186[1] = 1 for DDS1 in the example).
• p0187 — encoder 1 EDS number: shows which encoder data set each DDS assigns for the motor encoder; check that DDSs sharing one MDS do not assign different EDS here.
• r0949 — fault value: read it as a decimal number to identify the first DDS (lower 16 bits) and the second DDS (upper 16 bits).

The drive coasts down (OFF2) when this fault trips and must be acknowledged before it will start again. Acknowledging alone does not remove the cause: first correct the p0186/p0187 assignment as described above, then acknowledge the fault immediately and restart the drive.
