2: For a linear axis, the position tracking was activated for the load and measuring gearbox.
3: Position tracking cannot be activated because there is more than one data set (p0180).
4: A linear encoder is being used.
See also: p0404 (Encoder configuration effective), p0411 (Measuring gearbox, configuration)
Remedy: - use an absolute encoder.
- if necessary, de-select the position tracking (p0411 for the measuring gearbox, p2720 for the load gearbox).
- use a Control Unit with sufficient NVRAM.

F07556 Measuring gearbox: Position tracking, maximum actual value exceeded
Drive object: SERVO, VECTOR
Reaction: NONE
Acknowledge: IMMEDIATELY
Cause: When the position tracking of the measuring gearbox is configured, the drive/encoder identifies a maximum 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 (Rotary encoder pulse No.), p0412 (Measuring gearbox, rotary absolute gearbox, revolutions, vir-
tual), p0419 (Fine resolution absolute value Gx_XIST2 (in bits))
Remedy: - reduce the fine resolution (p0419).
- reduce the multiturn resolution (p0412).

value Gx_XIST2 (in bits))
A07557 (F) Encoder 1: Reference point coordinate not in the permissible range
Drive object: SERVO, VECTOR
Reaction: NONE
Acknowledge: NONE
Cause: The reference point coordinate received when adjusting the encoder via connector input CI:p2599 lies outside the
half of the encoder range and cannot be set as actual axis position.
Fault value (r0949, interpret decimal):
Limit value (absolute value) for the reference point coordinate.
Remedy: Set the reference point coordinate less than the limit value specified in the fault value.
See also: p2598 (EPOS reference point coordinate, signal source)
Reaction upon F: OFF1 (OFF2, OFF3)
Acknowl. upon F: IMMEDIATELY
A07558 (F) Encoder 2: Reference point coordinate not in the permissible range
Drive object: SERVO, VECTOR
Reaction: NONE
Acknowledge: NONE
Cause: The reference point coordinate received when adjusting the encoder via connector input CI:p2599 lies outside the
half of the encoder range and cannot be set as actual axis position.
Fault value (r0949, interpret decimal):
Limit value (absolute value) for the reference point coordinate.
Remedy: Set the reference point coordinate less than the limit value specified in the fault value.

Reaction upon F: OFF1 (OFF2, OFF3)
Acknowl. upon F: IMMEDIATELY
