Remedy: The fault should be resolved as follows:
- select encoder commissioning (p0010 = 4).
- reset position tracking, position (p2720.2 = 1).
- deselect 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
Component: None
Reaction: Vector: OFF1 (NONE, OFF2, OFF3)
Infeed: NONE
Acknowledge: IMMEDIATELY
Cause: When switched off, 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).
- deselect encoder commissioning (p0010 = 0).
The fault should then be acknowledged and, if necessary, the absolute encoder adjusted (p2507).

Acknowl. upon A: NONE
F07450 (A) LR: Standstill monitoring has responded
Message value: -
Message class: Application/technological function faulted (17)
Drive object: VECTOR_G
Component: None
Reaction: OFF1 (OFF2, OFF3)
Acknowledge: IMMEDIATELY
Cause: After the standstill monitoring time (p2543) expired, the drive left the standstill window (p2542).
- position actual value inversion incorrectly set (p0410).
- standstill window set too small (p2542).
- standstill monitoring time set too low (p2543).
- position loop gain too low (p2538).
- position loop gain too high (instability/oscillation, p2538).
- mechanical overload.
- Connecting cable, motor/drive converter incorrect (phase missing, interchanged).
- when selecting motor identification, select tracking mode (BI: p2655[0] = 1 signal).
- when selecting function generator, select tracking mode (BI: p2655[0] = 1 signal) and deactivate position control
(BI:p2550 = 0 signal).
Remedy: Check the causes and resolve.
