F33501 (N, A)
Encoder 3: Position tracking encoder position outside tolerance window
Drive object:
SERVO, VECTOR
Reaction:
OFF1 (NONE, OFF2, OFF3)
Acknowledge:
IMMEDIATELY
Cause:
When powered-down, the drive/encoder was moved through a distance greater than what was parameterized in the
tolerance window. It is possible that there is no longer any reference between the mechanical system and encoder.
Fault value (r0949, decimal):
Deviation (difference) to the last encoder position in increments of the absolute value.
The sign designates the traversing direction.
Note:
The deviation (difference) found is also displayed in r0477.
See also: p0413 (Measuring gearbox, position tracking tolerance window), r0477 (Measuring gearbox, position dif-
ference)
Remedy:
Reset the position tracking as follows:
- select encoder commissioning (p0010 = 4).
- reset the position tracking as follows (p0411.2 = 1).
- de-select encoder commissioning (p0010 = 0).
The fault should then be acknowledged and, if necessary, the absolute encoder adjusted (p2507).
See also: p0010 (Infeed commissioning parameter filter), p2507 (LR absolute encoder adjustment status)
Reaction upon N:
NONE
Acknowl. upon N:

F33502 (N, A)
Encoder 3: Encoder with measuring gearbox, without valid signals
Drive object:
SERVO, VECTOR
Reaction:
OFF1 (OFF2, OFF3)
Acknowledge:
IMMEDIATELY
Cause:
The encoder with measuring gearbox no longer provides any valid signals.
Remedy:
It must be ensured that all of the encoders, with mounted measuring gearbox, provide valid actual values in opera-
tion.
Reaction upon N:
NONE
Acknowl. upon N:
NONE
Reaction upon A:
NONE
Acknowl. upon A:
NONE
F33503 (N, A)
Encoder 3: Position tracking cannot be reset
Drive object:
SERVO, VECTOR
Reaction:
OFF1 (NONE, OFF2, OFF3)
Acknowledge:
IMMEDIATELY
Cause:
The position tracking for the measuring gearbox cannot be reset.
Remedy:
The fault should be resolved as follows:
- select encoder commissioning (p0010 = 4).
- reset the position tracking as follows (p0411.2 = 1).
- de-select encoder commissioning (p0010 = 0).
The fault should then be acknowledged and the absolute encoder adjusted.
Reaction upon N:
NONE
Acknowl. upon N:
NONE
Reaction upon A:
NONE
Acknowl. upon A:
NONE
