F07510 — Drive: Identical encoder in the drive data set

F07510 tells you that more than one encoder with an identical component number has been assigned to a single drive data set. The drive does not permit identical encoders to be operated together in one drive data set, so the configuration is rejected as a parameterization error. When the fault is active the drive coasts down (OFF2) and must be acknowledged before it will start again. The fault value in r0949 identifies the drive data set and the two encoders that collide.

• More than one encoder with an identical component number is assigned to a single drive data set.
• Within one drive data set it is not permissible that identical encoders are operated together.

1. Read the fault value in r0949, interpreted as a decimal number, and decode it (see below) to identify the drive data set and the two identical encoders.
2. In the affected drive data set, check which encoder is assigned as encoder 1 (p0187), as encoder 2 (p0188) and as encoder 3 (p0189) — for example, p0187[3] applies to drive data set 3.
3. Compare the component numbers of the encoders concerned; p0141 holds the component number of the encoder interface (Sensor Module).
4. Assign the drive data set to different encoders so that no two encoders with the same component number share one drive data set, then acknowledge the fault.

• The drive enters the fault value in r0949; interpret the value as a decimal number.
• The value is built up as: 1000 * first identical encoder + 100 * second identical encoder + drive data set.
• Example from the manual: Fault value = 1203 means: In drive data set 3, the first (p0187[3]) and second encoder (p0188[3]) are identical.

• r0949 — fault value: read it here as a decimal number to identify the drive data set and the two identical encoders.
• p0187 — Encoder 1 encoder data set number: shows which encoder is assigned to the affected drive data set as encoder 1.
• p0188 — Encoder 2 encoder data set number: shows which encoder is assigned to the affected drive data set as encoder 2.
• p0189 — Encoder 3 encoder data set number: shows which encoder is assigned to the affected drive data set as encoder 3.
• p0141 — encoder interface (Sensor Module) component number: read the component number here when comparing the encoders assigned to one drive data set.

The drive coasts down on this fault and must be acknowledged immediately before it will start again. Because the cause is the encoder assignment itself, first assign the drive data set to different encoders as described above; as long as two encoders with the same component number remain assigned to one drive data set, the drive raises F07510 again.
