4 Faults and alarms
4.2 List of faults and alarms
F07448 (A) Load gear: Position tracking, linear axis has exceeded the maximum range
Message value: -
Message class: Application / technological function faulted (17)
Drive object: B_INF, ENC, VECTOR_G
Reaction: Vector: OFF1 (NONE, OFF2, OFF3)
Infeed: NONE
Acknowledge: IMMEDIATELY
Cause: For a configured linear axis/no modulo axis, the currently effective motor encoder (encoder 1) has exceeded the
maximum possible traversing range.
For the configured linear axis, the maximum traversing range is defined to be 64x (+/- 32x) of p0421. It should be
read in p2721 and interpreted as the number of load revolutions.
Note:
Only the motor encoder in the currently effective drive data set is monitored here. The actual effective drive data set
is displayed in x = r0051 and the corresponding motor encoder is specified in in p0187[x].
Remedy: The fault should be resolved as follows:
- select encoder commissioning (p0010 = 4).
- reset position tracking, position (p2720.2 = 1).
- de-select encoder commissioning (p0010 = 0).
The fault should then be acknowledged and the absolute encoder adjusted.
Reaction upon A: NONE
Acknowl. upon A: NONE
F07449 (A) Load gear: Position tracking actual position outside tolerance window
Message value: %1
Message class: Application / technological function faulted (17)
Drive object: B_INF, ENC, VECTOR_G
Reaction: Vector: OFF1 (NONE, OFF2, OFF3)
Infeed: NONE
Acknowledge: IMMEDIATELY
Cause: When powered down, the currently effective motor encoder was moved through a distance greater than was
parameterized in the tolerance window. It is possible that there is no longer any reference between the mechanical
system and encoder.
Note:
Only the motor encoder in the currently effective drive data set is monitored here. The actual effective drive data set
is displayed in x = r0051 and the corresponding motor encoder is specified in in p0187[x].
Fault value (r0949, interpret decimal):
Deviation (difference) to the last encoder position in increments of the absolute value after the measuring gear - if
one is being used. The sign designates the traversing direction.
Note:
The deviation (difference) found is also displayed in r2724.
See also: p2722 (Load gear position tracking tolerance window), r2724 (Load gear position difference)
Remedy: Reset the position tracking as follows:
- select encoder commissioning (p0010 = 4).
- reset position tracking, position (p2720.2 = 1).
- de-select encoder commissioning (p0010 = 0).
The fault should then be acknowledged and, if necessary, the absolute encoder adjusted (p2507).

Reaction upon A: NONE
