Fault value (r0949, interpret hexadecimal):
ddccbbaa hex
aa: encoder data set number
bb: first incorrect bit
cc: incorrect parameter
cc = 0: incorrect parameter is p0430
cc = 1: incorrect parameter is p0437
cc = 2: incorrect parameter is r0459
dd: reserved (always 0)
Remedy: - check the encoder parameterization (p0430, p0437).
- check the pole position identification routine (p1982).
- use the matching encoder evaluation (r0458, r0459).

Reaction upon A: NONE
Acknowl. upon A: NONE
F07555 (A) Drive encoder: Configuration position tracking
Message value: Component number: %1, encoder data set: %2, drive data set: %3, fault cause: %4
Message class: Error in the parameterization / configuration / commissioning procedure (18)
Drive object: B_INF, ENC, VECTOR_G
Reaction: Vector: OFF2 (IASC/DCBRK, NONE, OFF1, OFF3, STOP2)
Infeed: OFF2 (NONE, OFF1)
Acknowledge: IMMEDIATELY (POWER ON)
Cause: For position tracking, the configuration is not supported.
Position tracking can only be activated for absolute encoders.
For linear axes, it is not possible to simultaneously activate the position tracking for load and measuring gears.
Fault value (r0949, interpret hexadecimal):
ddccbbaa hex
aa = encoder data set
bb = component number
cc = drive data set
dd = fault cause
dd = 00 hex = 0 dec
An absolute encoder is not being used.
dd = 01 hex = 1 dec
Position tracking cannot be activated because the memory of the internal NVRAM is not sufficient or a Control Unit
does not have an NVRAM.
dd = 02 hex = 2 dec
For a linear axis, the position tracking was activated for the load and measuring gear.
dd = 03 hex = 3 dec
Position tracking cannot be activated because position tracking with another gear ratio, axis type or tolerance window
has already been detected for this encoder data set.
dd = 04 hex = 4 dec
A linear encoder is being used.

Remedy: For fault value 0:
- use an absolute encoder.
For fault value 1:
- use a Control Unit with sufficient NVRAM.
Re fault value = 2, 4:
- if necessary, de-select the position tracking (p0411 for the measuring gear, p2720 for the load gear).
For fault value 3:
- Only activate position tracking of the load gear in the same encoder data set if the gear ratio (p2504, p2505), axis
type (p2720.1) and tolerance window (p2722) are also the same. These parameters must be the same in all drive
data sets, which use the same motor encoder (p187).
