Remedy: - check the encoder parameterization (p0430, p0437).
- check the pole position identification routine (p1982).
- use the matching encoder evaluation (r0458, r0459).

207555 <location>Drive encoder: Configuration position tracking
Message Component number: %1, encoder data set: %2, drive data set: %3, fault cause: %4
value:
Drive object: SERVO, VECTOR
Reaction: OFF2 (IASC/DCBRAKE, NONE, OFF1, OFF3, STOP1, STOP2)
Acknowledge: IMMEDIATELY (POWER ON)
Cause: The configuration of the position tracking 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 mea-
suring gear.
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 dez
An absolute encoder is not being used.
dd = 01 hex = 1 dez
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 dez
For a linear axis, the position tracking was activated for the load and measuring gear.
dd = 03 hex = 3 dez
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 dez
A linear encoder is being used.
See also: p0404 (Encoder configuration effective), p0411 (Measuring gear, configuration)
Remedy: - use an absolute encoder.
- if necessary, de-select the position tracking (p0411 for the measuring gear, p2720 for the load gear).
- use a Control Unit with sufficient NVRAM.
- 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.
207556 <location>Measuring gear: Position tracking, maximum actual value
exceeded
Message Component number: %1, encoder data set: %2
value:
Drive object: SERVO, VECTOR
Reaction: NONE
Acknowledge: IMMEDIATELY
Cause: When the position tracking of the measuring gear is configured, the drive/encoder identifies a maxi-
mum possible absolute position actual value (r0483) that cannot be represented within 32 bits.
Maximum value: p0408 * p0412 * 2^p0419
Fault value (r0949, interpret decimal):
Low word low byte: Encoder data set number
Low word high byte: Component number
See also: p0408, p0412, p0419
Remedy: - reduce the fine resolution (p0419).
- reduce the multiturn resolution (p0412).

tion absolute value Gx_XIST2 (in bits))
